Studying The Mechanical And Electrical Properties Of Polyester Resin Reinforced With Silica Particals

Abstract

A study has been made on mechanical properties of polyester resin matrix reinforced with weight fraction (10,20, 30&40) % of silica particles. The specimens were subjected to tensile test bending test (three point method), and hardness test .The experimental results indicate that the tensile strength of the matrix material were found to be significantly higher than those of the composite material (36%,36.1%,52%,57.5) while the young modulus of matrix material were found to be less than of composite material (14%,33%,42%, 45%). Test result also indicate that the flexural strength of the matrix material were found to be significantly higher than those of the composite material (6%,27%,29%,51) while the young modulus of matrix material were found to be less than of composite material(41%,50%,57.6%, 63%) . hardness of the composite materials are significantly higher than those of the matrix material (20%,28.6%,34%,43%) the enhancement in these properties are found to be directly proportional to the weight fraction of reinforcement materials. Test results also indicate that the electrical conductivity increased with increasing the silica concentrations.
