    Abstract

    The influence of the interface and fiber anisotropy on the performance of high-performance polyethylene (I) fiber-epoxy composites was investigated. The relatively low exptl. values for shear and transverse strength of the composites, incorporating surface-treated fibers, were caused by a change in failure mode from debonding to fiber splitting with increasing levels of adhesion. To obtain more quant. information about the role of fiber anisotropy on the strength of the composites, a finite-element micromechanics anal. was utilized to predict ultimate composite properties. Theor. values for transverse composite strength as obtained via micromechanics, assuming perfect adhesion, well agree with exptl. data for the composites incorporating surface treated fibers, indicating that the highly anisotropic character I fibers plays a predominant role in the structural performance of composites based on these fibers
