تأثير نسبة التقوية بالألياف على الخواص الحرارية و الميكانيكية لماد ة مركبة بوليميرية

Abstract EN

The objective of this research is to study the effect the change of reinforcement percentage by fibers on the thermal conductivity for polymeric composite material consist of conbextra epoxy (EP-10) resin reinforced by biaxial woven roving S–type glass fibers (٠º-٤٥º) 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 used reinforcement percentages (20%,40%,60%) to reinforced the mechanical tests specimens to calculated impact strength, tensile strength, flexural strength as illustrated in diagrams which represent the relation between thermal conductivity coefficient (k) with temperature and between mechanical properties and reinforcement percentages.
