Friction Optimization of Talc Powder-Reinforced Elastomers for Prosthetic Foot Application

Patients with lower limb amputation usually use prosthetic feet. Elastomeric material is an important part of feet since it can determine their safety and lifetime. The elastomeric should have high friction for safety, at the same time low wear a longer This research aimed to study optimum formulation talc-powder-reinforced silicone elastomer obtain during sliding contact. Taguchi orthogonal array L9 formula used achieve aforementioned goal. experiments multiple parameters, namely, type silicone, surface texture, amount catalyst, talc powder. results show that combination RTV 683, smooth 4% 60% powder most composition highest frictional force. It has higher force in comparison imported products, and, time, comparable products. hardness optimized materials However, tensile tear strengths need be improved.
