تأثير الطمر في التربة على الخصائص الميكانيكية و الفيزيائية لمتراكبات البولي إستر

Abstract EN

In this study Composite made of natural fibers (Jute ,Reed, Fronds palm) and unsaturated polyester resin and another artificial (Glass fiber) is investigated in this study by means of soil burial for 4 months.

The mechanical properties determine (tensile, Flexture strength ,Impact and Hardness) physical properties (water absorption and Biodegradability) before &after soil burial.

Scanning electron microscope (SEM) analysis was conducted to visualize the effect of the quality of adhesion between the fibers and matrix.

The soil burial investigation results revealed that natural fiber-polyester composites showed highest degradation percentage as compared to polyester resin and fiberglass.

As the amount of degradation in mechanical properties (tensile, Flexture strength , Impact and Hardness) for Unsaturated polyester reinforced with Jute (JC) is equal to (56%) , (34%) , (54%) and (10%), respectively, As for Unsaturated polyester reinforced with Glass fiber (G.C) accounted for (16%), (19%),( 25%), and (4.5%) respectively.
