THE EFFECT OF NATURAL MATERIALS ON MECHANICAL PROPERTIES OF COMPOSITE MATERIALS

Abstract

This research studied the mechanical properties of orange and pomegranate shells powdersreinforced unsaturated polyester with different weight fractions %Wf. The compositespecimens were prepared by hand lay-up technique and sectioned according to (ASTM)for tensile, impact, bending and compression tests to obtain modulus of elasticity, ultimatetensile strength, elongation percentage, compression strength, impact energy and fracturetoughness of the composite specimens. The results showed that the composite specimensreinforced with pomegranate shells powder give high mechanical properties compared withcomposites specimens reinforced with orange shells powder.
