Technical Report of National Aerospace Laboratory. Evaluation of Interlaminar Shear Strength Test Method for Heat Resistant Composite Materials

摘要

This paper describes the results of the investigation and evaluation of an interlaminar shear of carbon/carbon composite material (C/C materials) and silicon carbide/silicon carbide composite material (SiC/SiC materials). Data were collected by two test methods: a three-point flexural shear test method using a short beam specimen, and a compression shear test method using a double-notched specimen. The compression shear tests for C/C materials were carried out with fixing test jigs under various conditions, and the interlaminar shear strength of SiC/SiC materials was evaluated at the three air temperatures of 23 degrees C, 800 degrees C and 1000 degrees C.
