Abstract

Composites produced by incorporating high modulus fibers in brittle matrices such as epoxy resins can have outstanding mechanical properties. In particular, polydiacetylene single-crystal fibers, which have properties such as high stiffness, high strength, low creep, good thermal stability, and low density, are presented. The solid-state reactions relevant to the preparation of polymer single-crystal fibers and their structure and mechanical properties are discussed. In particular, structure is investigated by transmission electron microscopy, while mechanical properties such as elastic and plastic deformation and fracture behavior are investigated using conventional mechanical testing methods. The study of these polymer single-crystal fibers not only enables the development of a new type of reinforcing fiber but could also lead to significant advances of our understanding of the structure-property relationships in polymers.
