Ultrasonic Temperature Compensating Method for Tracking Decomposition Front in Silica-Phenolic Thermal Protection Material

What is it about?

Ablative thermal protection materials play a vital role in providing thermal protection for a wide range of aerospace vehicles and systems. As a result of high temperature environment around the vehicle ablative materials undergo degradation process and eventually lose their mass and thickness. In this study we present an ultrasonic method for tracking decomposition front of silica-phenolic ablative material.
