Mechanical properties of flax short fiber reinforced silicone rubber composites

Abstract

In order to improve the mechanical properties of short flax fiber reinforced silicone rubber composites, flax short fiber/silicone rubber composite was prepared with flax short fiber as reinforcement and silicone rubber as matrix. The effects of the length and content of flax short fiber on the tensile elastic modulus of composites were studied. The results show that the reinforcing effect of flax short fibers with different length and content on silicone-rubber-matrix composites is different. The tensile elastic modulus of the composite is the highest and breaking strain is the lowest when the content of flax short fibers is 1.26% and the length of flax short fiber is 2.5 mm. In the process of industrial production, different effects can be achieved by controlling the length and content of flax short fiber to reinforce the silicone rubber matrix.
