Project Objective

To prove the concept of detecting FRP de-lamination using commercially available ultrasonic devices.

Project Abstract

We propose to test the effectiveness of commercially available ultrasonic devices in detecting de-lamination. We will send samples to the manufacture of the ultrasonic devices, and procure an appropriate device. We will then set up test samples with various sizes and positions of de-lamination, and evaluate the ability of the ultrasonic device to detect them in blind studies.

Anticipated Benefits

Establishment of a non-destructive testing method for de-lamination of FRP sheets

Modal Orientation
