Micromechanical strength theory of hybrid composites

Abstract

Composite materials containing two or more types of fibers in a common matrix are called hybrid composites. Hybrid composites are attractive because tailoring of materials is easier than non-hybrid composites, and they are now widely used including aircraft, sports goods, and so on. This paper first reviews the research works on micromechanical strength of composites including hybrid composites. Next, stress concentration around broken fibers is calculated by means of a shear-lag assumption, which is necessary for a statistical strength theory. In the last part of this paper, a strength prediction is made by the Monte Carlo simulation.
