Effect of Percentage of Fibers Reinforcement on Thermal and

Abstract

The objective of this research is to study the effect the change of reinforcementpercentage by fibers on the thermal conductivity for polymeric composite materialconsist of conbextra epoxy (EP-10) resin reinforced by biaxial woven roving S–typeglass fibers )º٤٥-º٠( with density (550 g/cm2) where we used different percentage of fibers reinforcement to the resin (20%,40%,60%,80%) and studied the influence that on thermal conductivity for composite material due to this change, and we used Fourier equation to calculate the thermal conductivity coefficient (k),and we usedreinforcement percentages (20%,40%,60%) to reinforced the mechanical testsspecimens to calculated impact strength, tensile strength, flexural strength as illustratedin diagrams which represent the relation between thermal conductivity coefficient (k)with temperature and between mechanical properties and reinforcement percentages.
