Imperfection Detection: Detect Me If You Can

Reclamation needs portable tools to non-destructively evaluate the condition of existing fiber reinforced polymer (FRP) composite structures
Phase 2 Submission Deadline

Challenge Overview



The Bureau of Reclamation (Reclamation) is the largest provider of water and the second-largest producer of hydroelectric power in the United States.  Reclamation’s infrastructure uses all major civil engineering material classes, including steel, concrete, plastics, and composites, to achieve the performance, and service life needed.  Typical applications for composite materials include fiber-reinforced polymer (FRP) pipelines, tanks, and other specialized infrastructure components, which take advantage of composites’ excellent corrosion resistance, reduced weight, and other helpful materials properties.  Evaluation tools and methods for concrete and steel infrastructure are well established; however, FRP composite structures require new and more advanced evaluation techniques. 

As existing composite materials in our water infrastructure age, reliable and non-destructive methods to assess the condition of those composites structures in the field are needed.  Reclamation, in collaboration with the US Army Corps of Engineers (USACE), is sponsoring this challenge with the goal of developing portable tools that use non-destructive evaluation (NDE) methods to assess the condition of existing FRP composite structures.  Such tools may also be used to confirm the quality of newly-received FRP composite structures, like pipes or gates.

Challenge Guidelines

Deadline extended and intellectual property terms revised on June 15, 2021 (see details here). 

Background and Technical Details

Fiber reinforced polymer (FRP) composites are materials in which a polymer matrix is reinforced with fibers.  Thermoset resins such as epoxy, vinyl ester, and polyesters are commonly used as the polymer matrix, and glass, carbon, and aramid are common materials for the reinforcing fibers.  Fibers can be continuous (as in tows or woven fabric), or discontinuous (as in chopped fibers).  As with all composites, the FRP composite provides better performance than either material by itself.  While the fiber reinforces the matrix and provides resistance to cracks, the polymer matrix both distributes the load to the reinforcing fiber and protects the fiber from the external environment.  

Composites offer many performance advantages.  In addition to having excellent strength, they weigh less than other common construction materials (like concrete or metal), and they have superior resistance to environmental conditions.  Also, composites are very durable and require little maintenance.  Lastly, by taking advantage of the many different combinations of polymer matrices and fibers, composites can be tailored to meet a wide range of specific performance requirements.  Because of these many benefits, composites are used in many applications including automotive, construction, aerospace, marine, and sports and recreation. 

The ongoing use of FRP composite materials for federal civil infrastructure, at both Reclamation and USACE, in applications such as pipelines, tanks, and other specialized structures or components takes advantage of composites’ excellent corrosion resistance, reduced weight, and other helpful properties.  As composites continue to age in their various infrastructure applications, reliable methods of assessing their condition in the field are needed. The goal of this challenge is to develop portable tools that use non-destructive evaluation (NDE) methods to assess the condition of existing FRP composite structures.

For this Imperfection Detection challenge, Reclamation seeks ideas for field-applicable non-destructive methods of detecting and quantifying the presence and location of the following types of defects:

  • Cracks
  • Delamination
  • Fiber breakage

Although commercially available technologies that can detect these defects exist, they don’t adequately meet Reclamation’s needs for in-situ NDE.  State-of-the-art NDE technologies are typically meant to be used in a laboratory setting.  The equipment can be large, heavy, and power-intensive.  

Competitive ideas submitted to this challenge will result in prototypes that can rapidly detect and quantify at least one of the three types of defects listed above, using equipment that is portable, rugged, and easily used in field settings.  Prototypes must be able to operate in variable climate conditions, or through layers of biofouling.  Participants in Phase 2 will be given 300 x 300 x 25 millimeter (mm) (12 x 12 x 1 inch) composite panels, containing various defects, against which they can demonstrate their prototypes’ capabilities.  Prototypes should be designed for Reclamation’s use and evaluation with real-life conditions in mind.  In particular, prototypes should be able to work on and be easily moved across large-scale composite structures that may have complex geometries and variable thicknesses (which may be thicker than 1 inch and contain a non-FRP core layer), as are seen in gates, pipe, and pipe fittings.  It is expected that proposed solutions will have a cost comparable to the base methodology/ies normally used in laboratory settings.

Reclamation would like to be able to detect defects at the scales described and depicted in the table and diagram shown below. Demonstrating detection limits below these thresholds is of interest, but resolution and detection limits must be balanced against scan rate (speed). For example, a prototype that detects defects that are one order of magnitude smaller than the detection limits (see table below) at a scan rate of one square meter per hour would score lower that meets detection limits at a rate of one hundred square meters per hour. 

Benchmark performance specifications for each type of defect:

Type of defectDetection limit Other specifications
Cracks30 mm length parallel to fiber orientation, depth of 1 layer from backside, width of approximately 0.3 mm (see figure below)

Minimum: Detection of defect.  

Preferred: Ability to characterize x,y,z dimensions of defect and orientation with respect to fibers.

Delamination   2.5 mm diameter at 20 mm depth, gap of approximately 0.5 mm

Minimum: Detection of defect.  

Preferred: characterize total area of delamination and determine location (depth from surface)

Fiber breakage30 mm length perpendicular to fiber orientation, depth of 1 layer from backside, width of approximately 0.3 mm (see figure below)

Minimum: Detection of defect.  

Preferred:Ability to characterize x,y,z dimensions of defect and orientation with respect to fibers.


NDE methodologies that are of interest to Reclamation include:

  • Terahertz
  • Radiography
  • Shearography
  • Thermography
  • Ultrasound

This list is neither exhaustive nor limiting.  If you have other innovative approaches or combinations of approaches to propose, we want to hear about them!

Regardless of what you propose, it must be demonstrable within the 10-month Phase 2 development period.  Composite panels with engineered defects will be supplied to each Phase 2 team, so that they can demonstrate how well their technology performs.  These panels will be 300 x 300 x 25 mm (12 x 12 x 1 inch), and the engineered defects will vary in size and depth within the panels.  These panels will have been fully characterized by computed tomography (CT), and it is expected that teams will be able to identify and quantify most, if not all, of the engineered defects.  There is a possibility that teams may further distinguish their prototype’s performance by additionally detecting and characterizing unintentional manufacturing defects that may be present in their panels.

At the end of the development period, Phase 2 participants will submit a complete development report, including all data arising from laboratory demonstrations on the supplied composite panels.  If selected as a Phase 3 participant, you will send in both your prototype and the supplied panel.  Reclamation will use your prototype to confirm your reported results and further evaluate the prototype’s performance on composite pieces more representative of field conditions.  Prototype performance may be assessed using composite pieces that contain curvature, thicknesses that may exceed 25 mm, and non-FRP core materials.  Additionally, Reclamation will review the cost estimate provided and assess the prototype’s field-readiness, portability, and power requirements.  

Reclamation is interested in seeing this capability developed so that it is eventually available for use in the field.  They are not interested in manufacturing the devices themselves.  The final demonstration event at the close of Phase 3 is an opportunity for teams to demonstrate their prototypes to the Reclamation and USACE network of commercial partners.  There is a potential opportunity for post-challenge development work with a commercial partner.


Phase 1

Everyone is invited to participate in Phase 1.  The deadline to submit your responses is July 20, 2021.  Reclamation and USACE are interested in portable technologies that can be used in the field to assess the condition of existing FRP composite structures.  Whatever you propose must be something that can be successfully developed and demonstrated within the 10-month Phase 2 development window.  It is also important to remember that Phase 2 winners will be selected based on how well their prototypes detect and characterize engineered defects in supplied composite panels, but Phase 3 winners will be selected based on how their prototypes perform on test pieces that have curvature, complex geometries, and variable thicknesses.  

In addition to providing a strong scientific rationale and any preliminary data for your proposed approach, Phase 1 submissions must also include a realistic project plan that clearly outlines the timeline and path for Phase 2 that will enable your prototype to be ready for the Phase 3 evaluations and final demonstration event.

Submissions that have passed a pre-screening step - which removes non-responsive and/or incomplete submissions - will be reviewed by the Evaluation Panel.  The panel will select up to 5 of the most compelling submissions as Phase 1 winners.  Winning submissions will be selected based on how they score against the Phase 1 evaluation criteria, see below.  Each winner will receive $60,000 award money to support their prototype development efforts.  If Reclamation determines that none of the Phase 1 submissions are sufficiently compelling, they may elect to recognize the authors of the top three submissions with $15,000 each and end the challenge at this stage.


Phase 2

The Phase 2 prototype development period is approximately 10 months long, with a mid-point check-in that will occur in February 2022.  At the start of the development period, Phase 1 winners will each receive $40,000 of their award money and will schedule a mid-point check-in with Reclamation.  It is anticipated that teams will have regular engagement with Reclamation and HeroX throughout the development period. Teams are expected to alert Reclamation to changes in their project plan, unforeseen roadblocks, and important breakthroughs. Teams can also request time with a subject matter expert (SME) and ask for advice. In addition to development funds won from Phase 1, Phase 2 teams will also have up to 40 hours of access to SMEs.  The experts will be drawn from Reclamation and USACE, depending on the specific expertise required by a team.  During the mid-point check-in, each team will review with Reclamation and USACE their progress relative to the project plan submitted in Phase 1.  After successful completion of the check-in and when the teams demonstrate meaningful progress in accordance with their proposed project plan, teams will each receive the remaining $20,000 of the award money to aid in the continued development of their prototype.

At the end of the Phase 2 period, each team will submit a report that contains a summary of their development efforts, data resulting from their prototype’s evaluation of the provided composite panels, detailed descriptions of any improvements and/or changes made to the prototype since the mid-point check-in, and a video which demonstrates how the prototype is set up and operated.  The Evaluation Panel will score Phase 2 teams’ prototypes based on the reported results of their non-destructive evaluation of the provided FRP composite panels and their performance against their project plan.  See Phase 2 evaluation criteria for full details.  Up to three of the top-performing teams will advance to Phase 3 and will each receive an additional $10,000 to support travel and associated costs with participation in the Phase 3 final demonstration event.


Phase 3

Teams participating in Phase 3 will have roughly 4 weeks to deliver their working prototypes and the supplied composite panels to a specified Federal laboratory.  Reclamation and USACE will confirm the reported prototype performance in detecting defects on the supplied panel and will further evaluate the prototypes in a variety of conditions and against a range of composite samples with variable thicknesses (that may be greater than 25 mm), which may include a non-FRP core layer (such as polymer resin with fine aggregate) - some of these composite samples may be pieces retired from the field, pieces about to be deployed, or samples developed with engineered defects.  After a 14-week evaluation period, a final demonstration event will be held.  This is an opportunity for commercial partners of both Reclamation and USACE to interact with Phase 3 participants and to observe demonstrations of the different prototypes.  Reclamation has a strong interest in the eventual commercialization of promising technologies, and this event offers the potential for additional development and commercialization of one or more prototypes.  A final winner will be announced at the end of the event and will be awarded a prize of $50,000.

Challenge Updates

Imperfection Detection Challenge Update

Sept. 28, 2022, 11:34 a.m. PDT by Kyla Jeffrey

The Imperfection Detection Challenge seeks portable tools to non-destructively evaluate the condition of existing fiber reinforced polymer (FRP) composite structures. This is a difficult task and, as of yet, no Phase 2 team has been able to characterize defects on the supplied FRP panel.

Four of the five Phase 2 teams submitted reports of their development efforts and capabilities to date and no team was able to meet the challenge requirements. The four teams were asked to share how much time they would require to meet the challenge requirements and only two teams were able to provide a timeline estimate at this time.

Reclamation and USACE are inviting these two teams to participate in a Phase 2A. These teams will each receive an additional ~6 months of development time as well as $15,000 to support additional procurement of materials. Near the end of Phase 2A, each team will receive a second instalment of $15,000 upon successful completion of a mutually agreed upon milestone. At which time, Phase 2 evaluations and Phase 3 will continue as initially planned.

We would like to commend all five Phase 2 teams for their efforts to date.

And The Winners Are...
