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 ...

In this study, bullet-proof building panels are investigated. The aim of work is to verify whether the polyethylene-plywood withstand frontal impact with high-speed projectiles. Ultra-high molecular weight polyethylene (UHMWPE) a promising ballistic material due its favorable properties – significant toughness and high strength-to-weight ratio, meantime it lightweight. By setting different para...

Ultra-high molecular weight polyethylene (UHMWPE) woven fabrics have been shown to possess a high strength-to-weight ratio, low density, high-energy absorption, and abrasion-resistant properties. When subjected dynamic impact, the primary failure mode of UHMWPE fabric is yarn pullout, which results from poor inter-yarn friction between weft warp yarns. This work investigates potential use zinc ...

The modern orthopaedic implants for applications in hips, knees, shoulders, and spines are composed of hard metal alloys or ceramics a tribological sub-component that is made soft materials, with good frictional properties—e.g., UHMWPE (Ultra High Molecule Weight Polyethylene). need to be machined into their final shape after the polymerization consolidation blank profile near net shaped implan...

Ultra-high molecular weight polyethylene (UHMWPE) fibers are used in ballistic composites due to their high tenacity; unfortunately, use structural remains limited poor adhesion with polymer matrix materials.
