Abstract

Aim of this study to Preparing a composite materials reinforced with natural particles and fibers which environmentally friendly materials, low cost, available, and have acceptable mechanical properties for use in the manufacture of prosthetic limbs, especially the socket part. Mechanical tests (tensile, bending, and impact) and physical tests (density and water absorption) were carried out. The results showed that when adding (4) layers of Luffa fibers (Lu) and (6) layers of Perlon fibers (P) to the composite material, it led to a significant increase in the mechanical properties, and that the best composite material obtained was when the layers were arranged in order.
