EFFECT OF REINFORCING BY FIBERS ON THERMAL CONDUCTIVITY AND MECHANICAL PROPERTIES OF THERMOSETTING RESINS

Abstract

The objective of this research is to study the effect of reinforcement by carbon fibers as woven roving (°90-°0) with density (1.75gcm3)on thermal conductivity for unsaturated polyester resin after reinforcing it by different percentage of fibers (20%, 40%,60%) and we used Fourier equation to calculate the thermal conductivity coefficient (k) . Also the mechanical properties of this resin was calculated with the same reinforcing percentage of fibers and these properties included : impact strength , tensile strength , compression strength , flexural strength , and hardness . The results show that improvement in thermal and mechanical properties after reinforced by fibers , and these properties will rise as increased in reinforcement percentage .
