Mechanical and tribological properties of short discontinuous UHMWPE fiber reinforced UHMWPE
Polymer Bulletin, 1997The tribological properties of Ultra-High Molecular Weight Polyethylene have generated new concern regarding the long-term clinical performance of total joint replacements. To extend the lifetime of artificial joints, it is necessary to decrease the wear rate of UHMWPE. One possible solution is the incorporation of UHMWPE fibers.

Journal of Thermal Analysis, 1997
The thermal behaviour of ultra-high molecular weight polyethylene (UHMWPE) of different molecular weights was examined by thermal analysis methods. The melting temperatureTm and the heat of melting δH were measured by the DSC method. The thermooxidative degradation process was investigated by using a MOM Q-1500 D derivatograph at various heating rates ...

Removal or transfer of material from contacting surfaces due to their relative movement under load. Wear can be measured by mass change, volume measurement or by the depth of the wear tracks. The two inevitable consequences are shedding of wear products and change of the geometry of the articulation.

Processing of UHMWPE and HA/UHMWPE nanocomposite for biomedical applications
2014Ultrahigh molecular weight polyethylene (UHMWPE) is an implant material for orthopedic implants because of its excellent mechanical properties. However, its applications were limited by the poor processability, particularly its use as matrix materials for bone-analogue.

Stabilisation Of Uhmwpe With Vitamin E
2006Ultra-high molecular weight polyethylene (UHMWPE) has been the material of choice for load-bearing articular components used in total joint arthroplasty in the past 30 years. However, the durability of the whole implant has often been compromised by oxidation of UHMWPE components.

Statistical wear analysis of PA-6/UHMWPE alloy, UHMWPE and PA-6
Wear, 2001This paper, based on an orthogonal experimental design and analysis method, reports the wear of a blend of polyamide-6/ultrahigh molecular weight polyethylene (PA-6/UHMWPE), using a pin-on-disc test, and rubbing against a stainless steel counterface. The wear behavior of PA-6 and UHMWPE was also investigated for the purpose of comparison.

Dispersion of Pristine Cnt in Uhmwpe Solution to Prepare Cnt/Uhmwpe Composite Fiber
Polymers and Polymer Composites, 2014CNT dispersion in polymer matrices uniformly remains a challenge. Uniform dispersion of carbon nanotube (CNT) within ultra-high molecular polyethylene (UHMWPE) solution is the first step to achieve CNT/UHMWPE fibers with excellent properties. Several approaches have been tried.

Nanotribological Properties of UHMWPE/Quartz Composites
Materials Science Forum, 2005Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane as a cross-linking agent for UHMWPE matrix, were tested in nanoindentation and nanowear.

Modeling UHMWPE wear debris generation
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2006AbstractIt is widely recognized that polyethylene wear debris is one of the main causes of long‐term prosthesis loosening. The noxious bioreactivity associated with this debris is determined by its size, shape, and quantity. The aim of this study was to develop a numerical tool that can be used to investigate the primary polyethylene wear mechanisms ...

Wettability of nano-epoxies to UHMWPE fibers
Journal of Colloid and Interface Science, 2006Ultra high molecular weight polyethylene (UHMWPE) fibers have a unique combination of outstanding mechanical, physical, and chemical properties. However, as reinforcements for manufacturing high performance composite materials, UHMWPE fibers have poor wettability with most polymers.
