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 کاملDiscontinuous fiber-reinforced composites above critical length.
Micromechanical physics of critical fiber length, describing a minimum filament distance for resin impregnation and stress transfer, has not yet been applied in dental science. As a test of the hypothesis that 9-micron-diameter, 3-mm-long quartz fibers would increase mechanical strength over particulate-filled composites, photocure-resin-pre-impregnated discontinuous reinforcement was incorpora...
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 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 کاملTensile test on pine needles and crack analysis of pine needles short fiber reinforced composites
Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...
