Effect of Fiber Inclination on Crack Bridging Stress in Brittle Fiber Reinforced Brtttle Matrix Composites
THE MECHANICAL behavior of brittle matrix composites is strongly affected by the bridging of cracks by fibers. In random fiber composites, libers can lie at an angle to the crack plane. Under such conditions, the bridging stress for a certain crack opening is governed by various micromcchanisms including fiber debonding, fiber bending and rupture as well as matrix spailing. While fiber debondin...
متن کاملEffect of Apparent Fiber Strength and Fiber - Matrix Interface Properties on Crack Bridging in Cementitious Composites
This article proposes a new theory for predicting the crack bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of Random Short Fiber Reinforced Cement Composites (RSFRCC) under tension is limited to specific constituent properties: friction dominant fiber-matrix interface and complete fiber pul...
متن کاملEffect of inclination angle on fiber rupture load in fiber reinforced cementitious composites
A model has been formulated for analyzing the influence of fiber inclination angle on its rupture load in fiber reinforced cementitious composite. As a stiff fiber is pulled with an angle to the direction of pulling, the fiber rupture load decreases compared to the case with zero inclination angles. This phenomenon is called fiber apparent strength (defined as rupture load divided by fiber cros...
متن کاملEffect of fiber surface treatments on the fiber-matrix interaction in banana fiber reinforced polyester composites
Cellulosic bers have been used as cost-cutting llers in plastic industry. Among the various factors, the nal performance of the composite materials depends to a large extent on the adhesion between the polymer matrix and the reinforcement and therefore on the quality of the interface. To achieve optimum performance of the end product, suf cient interaction between the matrix resin and th...
متن کاملHomogenization of Fiber Reinforced Brittle Materials: the Intermediate Case
We derive a cohesive fracture model by homogenizing a periodic composite material whose microstructure is characterized by the presence of brittle inclusions in a reticulated unbreakable elastic structure.
