Abstract:

The principal objective of this study was to determine the mechanical properties, tensile yield, ultimate strength, and Youngs modulus of elasticity of a silica fabric reinforced phenolic composite at temperatures above the cure level. The proposed application for this class of material as an ablative liner of a rocket nozzle skirt extension requires such engineering data for temperatures ranging up to 3000F so that design safety margins can be based on a thermostructural analysis.
