The data included here provides a basis for understanding "Interior morphology of high-performance polyethylene fibers revealed by modulus mapping" (K.E. Strawhecker, E.J. Sandoz-Rosado, T.A. Stockdale, E.D. Laird, 2016) [1], in specific: the multi-frequency (AMFM) atomic force microscopy technique and its application to ultra-high-molecular-weight Polyethylene (UHMWPE) fibers. Furthermore, the...

Delamination is a common failure mechanism in ultra-high molecular weight polyethylene (UHMWPE) tibial inserts [Wright and Rimmnac, 1988]. Changes in polyethylene mechanical properties, such as subsurface embrittlement due to oxidation, may promote crack propagation. The assessment of through-thickness properties may, therefore, provide insight into delamination mechanisms. Using the small punc...

A composite hip prosthesis (CHP) made from alumina reinforced ultra high molecular weight polyethylene (UHMWPE) was designed and manufactured. The main objective of the study was to fabricate the composite hip prosthesis which would be an ideal replacement of metallic one as bone is a composite material consisting of collagen fibre matrix and embedded hydroxyapatite mineral. With this idea we d...

El polietileno de ultra alto peso molecular (UHMWPE por sus siglas en inglés) ha sido el estándar oro para los reemplazos rodilla durante más cinco décadas. Este biomaterial, utilizado ampliamente sector ortopédico, constantemente modificado disminuir su tasa desgaste las prótesis rodilla. Hoy día, totales tienen una supervivencia del 95 % después 10 años, 88.7 15, y 82 25 años. Sin embargo, la...

UHMWPE has exhibited excellent performance when used as contact surfaces in tribological contacts. Traditionally, only grades, with narrow particle size and molecular weight distribution, have been deemed suitable for such applications. Now, various grades are available that different from each other based on their distribution. The question of whether the affects its properties presents a rese...

For the production of high-performance polyethylene fibers and tapes by ultra drawing, using solid-state processing disentangled nascent ultra-high molecular weight (UHMWPE), maximum draw ratio is an important design parameter, as it determines degree chain alignment and, therewith, properties final product. It would, therefore, be advantageous to have a fast scanning method estimate drawabilit...

INTRODUCTION The majority of current artificial hip implants use a material combination of ultra-high molecular-weight polyethylene against metal or ceramic. However, it is well documented that the wear debris from these prostheses contributes to osteolysis and ultimate failure of the prosthesis, hence alternative materials have been sought, such as metalon-metal and ceramic-on-ceramic [1]. Mor...
