High Strain Composites

Abstract

This review paper provides an introduction to high strain composites, a field of research that encompasses structures that undergo large deformations through composite materials capable of large strains. Unique qualities of the field are defined and its history is presented from beginnings in deformable metallic structures to current high strain composites using carbon fibers. High strain composites are presented as two classes: those with relatively stiff matrix materials and those with soft or softenable matrix materials. For each class, a survey and references are provided for materials, testing, mechanics, and examples of past structures. While there are broader applications, the paper focuses on high strain composites used in deployable space structures.
