Paper Abstract

This paper describes metal based active or multifunctioal structural material systems suitable for smart structures developed by simple and innovative methods without using sophisticated and expensive actuator/sensor materials. The following topics are mainly examined: (1) the proposed active material based on SiC/Al composites was fabricated and its actuation was examined by fundamental experiments to investigate the effect of fiber distribution on maximization of deformation, reproducibility of deformation during heating cycles, the effect of fiber length on thermal deformation, and some other aspects, (2) a nickel based active composite aiming at high temperature use was fabricated and its workable temperature was investigated, and (3) a multifunctional aluminum-matrix composite was made by embedding Ti oxide/Ti composite fiber in an aluminum matrix active composite for generation of heat for actuation and sensing temperature/deformation.
