Student Involvement

Undergraduate students will perform the testing, a graduate student will help with development.


Project Objective

To develop protocols for non-destructive testing (NDT) of FRP laminates.


Project Abstract


We will develop and use the following NDT methodologies for assessing the performance of FRP laminates:

  1. Surface roughness of concrete substrate, before FRP laminate installation, using a laser profilometer.
  2. Fiber alignment of installed FRP sheets using video image processing.
  3. Delamination of FRP Sheets using impact echo testing.
  4. FRP bond strength using non-destructive pull-off tests.

Anticipated Benefits

Will advance the state of the art in NDT testing of FRP laminates.
