516 Compression Strength of 3-D Heat-Resistant Textile Composites with Woven Optical Fibers

Abstract

It is expected to apply the smart structure to the aircraft by embedding optical fibers in the composite materials. The influence of the existence of optical fiber, which have usually larger diameter than reinforced fibers, on the strength properties has been studied for 3-D heat resistant composites under compression loading. In this study, we investigated the effect of the optical fiber direction and the reinforced fiber direction surrounding the optical fiber on the compression strength including the comparison with 2-D textile composites in which the out-of-plane yarn was eliminated.
