Abstract

The polymeric matrix, although much weaker than the fibers, plays the dominant role in fatigue cycling of composites. Investigations have been made on the fatigue behavior of pure polymers in tensile, compressive and shear loading. The question arises, whether or not the matrix behaves differently as bulk material or as matrix in a fiber composite? In most cases no correlation has been found, but epoxy as a matrix behaves better in a composite than as a bulk material. Some explanations for this behavior will be discussed.
