Improved the Tensile Properties of UHMWPE Reinforced by Short Fiber of PAN for Meniscus Knee Joint Replacement

Abstract

Ultra high molecular weight polyethylene (UHMWPE) was usually used in cartridge of KJR due to possess excellent mechanical properties such as self-lubricant, impact strength and biocompatibility but with the time is failed therefore the present study would improve the tensile properties: tensile strength, elastic modulus and elongation at the break to increased service life of joint by addition different weight fraction (1,3,5,7and 9) w.t % short fibers of PAN. The tensile properties were increased spatial at 5% PAN. The FE-SEM test was be done to confirm the interface bonding between matrix and PAN fibers which allow to transfer loud from matrix to fiberthus enhanced the properties of UHMWPE.
