Prosthetic upgrades are specialized prosthetics that enable patients to participate in more demanding recreational activities, such as running. This study examines the use of prosthetic limbs, specifically athletic foot. The current research focused on manufacturing and production properties an samples Foot made from composite materials based a polymethyl methacrylate resin (PMMA) reinforced wi...

To solve the problem of insufficient protective performance existing body armor, an impact-resistant shear stiffening gel (SSG) with excellent flexibility and formability was innovatively used as buffer plate for then combined ultra-high molecular weight polyethylene (UHMWPE) ballistic panel to form a UHMWPE/SSG composite armor. Based on impact experiment numerical simulation, effect performanc...

Until the advent of novel Enders catalysts, nonlinear rheological characterization polyethylene (PE) blends, containing up to 50 wt. % ultra-high molecular weight PE (UHMWPE, with average Mw > 106 g/mol) was unattainable. In this study, by melt blending a commercially available high-density (polymer matrix) and PE-reactor-blends (RBs), multimodal blends were prepared, their viscoelastic ...

The mechanical properties of fiber-reinforced composites are largely dictated by fiber-matrix interactions, where a well-adhered interface is desired. Ultra-high molecular weight polyethylene (UHMWPE) fibers suffer from poor interfacial due to their smooth and inert surface. Therefore, enhancing the such will lead an increased use in structural applications high modulus, tenacity, low density, ...

Ultra-high molecular weight polyethylene (UHMWPE) is a relevant thermoplastic in industry and well-proven standard biomaterial joint replacements. To enhance its tribological properties while preserving bulk ones, composite coatings on UHMWPE substrate were prepared using non-functionalised graphene nanoplatelet (GNP) at reinforcement concentration of 0.1–5 wt% two mechanical mixing techniques ...

INTRODUCTION: There is a need for a structural fatigue test method applicable to UHMWPE acetabular liners. Yet, for these implants, there are currently no standards that specify a structural fatigue test such as those that exist for other implants. The aim of this work was to develop a simple and practical fatigue test method based on the most relevant techniques previously reported in the lite...
