Effect of Reinforcement on Flexural Properties of Brittle Composites

Abstract:

The flexural properties in terms of ductility of laminated brittle composites have been studied experimentally in the laboratory. Test specimens consisting of variable layers of mesh were prepared and tested under third point loadings. It was observed that the brittle matrix altered it properties and behaved as the ductile matrix even with small amount of ductile materials. The causes of the change in the properties have been clarified by analyzing the experiment data. The experimental results were verified by the theoretical formulation. The formulation showed that the flexural modulus of the entire section of brittle composites obtained by section analysis is equal to the modulus of ductile layers plus a factor of the difference of modulus of ductile and brittle layers. This factor is third order of ductile layer causing flexural properties in brittle composite even with 10% of ductile materials.
