Quasicrystalline Metal Powder: A Potential Filler for UHMWPE Composites

The mechanical and thermal behavior of ultra-high molecular weight polyethylene (UHMWPE)/metallic quasicrystal powder (MQP) composites are evaluated at filler volume fractions (∅f) 0.01, 0.02, 0.06 0.15. MQP is based on an aluminum alloy, synthesized characterized to act as a for UHMWPE. preparation the was conducted by compression molding. Morphological analysis reveals larger smaller MPQ particles, being well distributed, mechanically anchored in matrix. melting temperature maintained after adding filler, while crystallinity values decreased. When MQP, improvement stability observed increases both initial maximum loss rate temperatures (Tmax). However, when about 700°C all present oxidation due presence. Pukansky model shows that have better interfacial adhesion. This confirmed Nicolais-Narkis equation. contributes increase modulus elasticity composite respect others. elongation break reduced 0.15 composite. higher fraction increased stiffness UHMWPE, reflecting its potential use reinforcement.
