Abstract : The role of the fiber/matrix interface on composite structural integrity and strength is discussed. The major part of the information contained herein is drawn from the published literature. Some recent results obtained by the author and his associates are included to project some current thinking. Methods for measuring and predicting interface bond stresses and interface bond strength are described. Geometric and material variables which influence interface stress and interface bond strength are identified. The dependence of composite fracture surface characteristics on bond strength is illustrated. Parameters for selecting constituents to yield specified interface bond strength are recommended.
