تأثير التقوية بالألياف الصناعية على الخواص الميكانيكية للراتنجات المتصلبة بالحرارة

Abstract EN

The objective of this research is adding different percentage of glass fibers (20%,40%,60%) to reinforced vinyl ester resin and study the effect of this on mechanical properties for result composite material which includes impact strength, tensile strength, and flexural strength .

Mechanical properties for vinyl ester resin were extracted before reinforced by fibers, then the resin was reinforced by different weight percentage from glass fibers and studied its effect on the above mechanical properties .It has shown an improvement in these mechanical properties after reinforcement by glass fibers where the value of mechanical properties will increase with increasing percentage of reinforcement.

Impact strength increased from(20Kj/m2) to (201Kj/m2), tensile strength from(70Mpa)to (321Mpa),and flexural strength from(0.12Mpa)to (0.217Mpa), for reinforcing percentages 0% and 60% from glass fibers respectively .
