تحسين بعض الخواص الميكانيكية لمادة بوليميرية ذات الأساس من راتنج الأيبوكسي المدعم بألياف الصلب المنخفض الكربون

الملخص EN

In the present study, specimens of composite material were prepared by Hand lay- up molding method.

The epoxy resin was reinforced by low carbon steel fibrous at different weight ratios (2, 4, 6)% by the random distribution of steel fiber in the resin.

Mechanical properties were studied through (Bending strength, Impact strength and Hardness) tests.

The results showed an increase in bending strength of (63%) in the percentage of reinforcement (4%).

As for the impact strength, the results also showed an increase of (15%) in the percentage of reinforcement (4 %) , while the rate of increase in the value of hardness was (18%) in the percentage of reinforcement(4%).
