In the application of heat resistant composites to structural members in the high temperature atmosphere, it is very important to evaluate their mechanical behavior in high temperature atmospheres. This papers described a high temperature test system to evaluate high temperature elongation and tensile strength of heat resistant composites in the air. The preliminary strength tests of two composite materials, SiC (Silicon Carbide)/LAS (Lithium AluminoSilicate) and SiC/SiC were conducted from room temperature to 1300 C in the air using a displacement measuring system with two pairs of simple laser sensors.
