摘要

Polymeric fiber-composites offer definite advantages as potential "adaptive" damping material systems that can be tailored to possess a pre-determined "time-memory". In this paper, simultaneous optimization of damping, stiffness and specific weight of a class of such material is carried out in conjunction with the underlying microstructure. The obtained results show that short aligned-fiber reinforced composites have superior design flexibility and damping properties as compared with those of long aligned-fiber composites. Here, in order to increase the damping, it may be necessary to sacrifice the stiffness and vise-versa.
