Abstract

A combined analytical/experimental investigation is described of the behavior of a unidirectional brittle-matrix composite under longitudinal tension. A modified shear lag model is used to relate the in-situ matrix tensile strength, residual stress and interface shear strength with measured experimental data. The necessary data are the macroscopic stress-strain curve and the microscopic failure mechanisms, such as matrix crack initiation, multiplication and saturation. Results show that the minimum crack spacing is approximately 8 fiber diameters and the interfacial shear strength is approximately 1.4 times the matrix tensile strength.
