Abstract
The main objective of this work is to study the effect of adding vegetables oils into high density polyethylene (HDPE) on the frictional behavior of the composite. Vegetables oils were added in 2, 4, 6, 8 and 10 wt. % content. The proposed composites are planned to be used in hip or knee joint to reduce friction and wear of HDPE free of oil. The hardness of the proposed composites is measured by shore D durometer hardness analyzer. Friction of the proposed composites is measured by pin on disc tester. Based on the experiments, it is observed that the friction coefficient is reduced by increasing oil content and hardness increased with increasing oil content. The experimental results suggest the composites to be used as bearing materials in such hip joints.
