Abstract: Discontinuous Random Fiber Reinforced Composites (DRFRC) exhibit different behaviors depending on their microstructural properties. Small fraction of fiber rupture can have a beneficial effect on the tensile and fracture energy properties of the composite. This paper briefly summarizes the results of an analytical model that predicts the pre-peak and post-peak bridging stress-COD relationship which accounts for fiber pull-out and rupture. The model can be used to optimize the design of DRFRC in terms of composite tensile strength and fracture energy.
