Yarns of fiber assemblies such as ropes would abrade with each other during repeated stretching or bending. The yarn on abrasion failure is a main reason for the final assembly result relative movement to other. To explore influencing factors and mechanism, this work, taking Ultra High Molecular Weight Polyethylene Fiber (UHMWPE) research object, discussed influences abrading frequency tension ...

Most total knee replacement joints consist of a metal femoral component made from a cobalt-chromium- molybdenum (CoCrMo)-alloy and a tibial component with an ultrahigh molecular weight polyethylene (UHMWPE) bearing surface. Wear of the UHMWPE remains the primary disadvantage of these implants. The allergic potential ascribed to CoCrMo-alloys is a further concern. Other metallic alloys with and ...

In the present work, multiwalled carbon nanotube (MWNT) reinforced UHMWPE composite films were prepared by electrostatic spraying followed by consolidation. X-ray diffraction and differential scanning calorimetry studies showed a decrease in the crystallinity of UHMWPE due to the nature of the fabrication process as well as addition of MWNT. Tensile test showed an 82% increase in the Young’s mo...

Bone plates are essential for bone fracture healing because they modify the biomechanical microenvironment at site to provide necessary mechanical fixation fragments. This paper addresses use of composite in long-bone fractures such as transverse femur. However, stress shielding due metal can be reduced by designing implants with Bio-composites that involve Ultra high molecular polyethylene rei...

Managing fractures of distal humerus in patients with rheumatoid arthritis (RA) is technically challenging. Total elbow arthroplasty (TEA) is one of the treatment options for these fractures. While elbow motion is largely regained by TEA, comminuted condyle fragments are often ignored. Although numerous approaches for repair of condylar fragments around TEA are described, any universal fixation...

Understanding friction between material pairs is very crucial when utilizing the materials in various applications, including mechanical and biological systems. In the present investigation, efforts were made to study the influence of surface texture and roughness on friction and transfer film formation during sliding of Ultra High Molecular Weight Polyethylene (UHMWPE) pins against steel plate...

This paper proposes a new method to estimate the roughness changes from topographic features of microscopic surfaces during an engineering wear process. We demonstrate that the evolution of the significant upcrossings of surface topography is the most efficient way to estimate the roughness changes associated with the small-scale changes during the time of wear process. The motivation of this w...

Abstract The proposed research work is addressed to the study of wear behavior Ultra High Molecular Weight Polyethylene (UHMWPE) under contact with a rounded pin in Ti6Al4V alloy, which largely used for production last generation prosthetic implants by electron beam manufacturing (EBM). tests UHMWPE are carried out dry or presence lubricants fluids that characterized tribological tests, wet‐abi...

The crystallographic texture evolution of ultra high molecular weight polyethylene (UHMWPE) subjected to different strains (up engineering 3.00) under uniaxial tension is presented in this work. A somewhat linear with 60% crystalline region and 40% amorphous has been used study. Wide angle X-ray diffraction utilized study the undeformed deformed UHMWPE samples help pole figures. components have...

Catalytic polymerization in compartmentalized aqueous or non-aqueous media, respectively, with functional-group tolerant Ni(ii) catalysts yields low-entangled UHMWPE.
