Ropes of ultra-high-molecular-weight polyethylene (UHMWPE) are replacing steel wires in many applications and nondestructive testing to monitor their condition is scientific commercial interest. In this work, wide-angle X-ray scattering (WAXS) combined with linear discriminant analysis (LDA) proposed as classification method distinguish between healthy damaged UHMWPE ropes. Healthy (as produced...

Mechanical behavior of Ultra-High Molecular Weight Polyethylene (UHMWPE) under high-velocity impact is critical for the design soft armor vests. Several types UHMWPE are available with different mechanical properties. However, no validated methodology has been published in literature to analyze influence stacking sequence combining materials maximize ballistic limit. In this work, a combined ex...

The mechanical properties of polyethylene (PE) materials are greatly influenced by their molecular structures, environmental temperature, and strain rate. In this study, static dynamic compression tests were performed on two semicrystalline PE materials—ultrahigh weight (UHMWPE) high-density (HDPE). stress–strain curves HDPE UHMWPE under uniaxial at temperatures −40–120 °C rates 0.001–5500 s−1 ...

Abstract Composite armors are widely used in the protection of human body and special vehicles due to their excellent ballistic performance. In this study, impact response SiC ceramics/Ultra-High Molecular Weight Polyethylene (UHMWPE) composite plate subjected fragment simulating projectiles (FSP) is investigated numerically. The influences head shape ceramic column position on failure modes, l...

Chemically expanded graphite (CEG) has recently been identified as promising reinforcement for polymer composites with the ability commercial up-scaling. In this work, silane and polydopamine functionalized CEG were successfully synthesized employed to prepare ultra-high molecular weight polyethylene (UHMWPE) nanocomposites an enhanced interfacial compatibility. Characterisation of indicated a ...

Introduction Radiation cross-linking was developed in order to improve the wear resistance of UHMWPE in total joint replacements [1]. Oxidationinducing free radicals formed during the irradiation process are eliminated through melting [2]. Without free radicals present, irradiated and melted UHMWPE has been considered oxidatively stable. However, with minor oxidation being observed in this mate...

Introduction: Wear particles from orthopaedic implants have been shown to affect both initial osseointegration and subsequent bone remodeling of total joint replacements (TJRs). Continued production and exposure to particles over time adversely affects bone formation and resorption, resulting in periprosthetic osteolysis. Current animal models of particle-induced periprosthetic osteolysis have ...
