Compressive Strength of Unidirectional Composites

A simple equation which can describe the compressive behavior of uni directional composites has been derived. With this equation, the effects of resin stiffness, fiber anisotropy, fiber misalignment and waviness, fiber/matrix interface, and void content on composite compressive strength can be assessed quantitatively and qualitatively. Fur thermore, the equation can help determine the failure modes of composites under com pression.
