“…HDPE, with the same chemical structure as UHMWPE, has also been widely used as bearing materials due to its excellent mechanical properties, low cost, and relatively good tribological properties. 26 HDPE-based nanocomposites have good processability due to the low viscosity of HDPE at elevated temperatures. Results obtained from studying HDPE nanocomposites may have potential implications and contributions to the study of UHMWPE nanocomposites.…”

Carbon nanofibers (CNFs) with silane coatings were used as the reinforcement to enhance the mechanical and tribological properties of high-density polyethylene (HDPE) at different loading levels (0.5 wt% and 3 wt%). To improve the interfacial bonding between the CNFs and HDPE matrix, two types of silane coating thicknesses, 2.8 nm and 46 nm, were applied onto oxidized CNFs. Mechanical properties of the HDPE/CNF nanocomposites including Young’s modulus, ultimate stress, strain at fracture, as well as work of fracture, were investigated through tensile testing. The wear tests were performed on a pin-on-disk tribometer under the bovine serum lubricated condition. The coefficient of friction of the materials in contact with steel balls was monitored over the duration of the wear test. The addition of CNFs not only decreased the coefficients of friction of the nanocomposites, but also reduced their wear rates. The thicker silane-treated CNFs were found to be more effective in reducing the coefficients of friction and elongating the strain of fracture compared with the pristine CNFs and thinner silane-treated ones. The biocompatibility of the nanocomposites against a mouse osteoblast precursor cell line was also evaluated. Among the several types of nanocomposites, the one reinforced with the thicker silane-treated CNFs (46 nm) at 0.5 wt% loading level yielded the highest strain at fracture, the best wear resistance with a wear rate reduction of nearly 57.9% compared to the neat HDPE, and good biocompatibility, making it a promising material for biomedical applications.

There is a growing demand for the development of new polymer matrix composite materials that exhibits high strength, high wear resistance, good rigidity and less weight. In this work, an attempt has been made to develop a novel carbon fibre reinforcement polymer (CFRP) composite with stainless steel (SS 316) wire mesh and to investigate its tribological characteristics with the objective of improving the wear resistance. The pin-on-disc experiment was performed on the fabricated CFRP-SS316 fibre metal laminate by using EN31 steel (high carbon alloy) pins. Wear rate and coefficient of friction have been examined by conducting four experiments on CFRP-SS316 laminate. The process parameters used for this investigation includes applied load, sliding velocity, sliding distance and speed. Experimental results showed that the wear rate increases on a CFRP-SS316 disc laminate when the load increases gradually from 10 N to 40 N. The minimum wear rate of 16.34 mm 3 /N was obtained for 10 N applied load.

“…The 3D morphology and its matching depths in the GO/UHMWPE composites are demonstrated in Figure . To calculate the scratch depth, the curvature of the surface was taken into account by approximation of the surface by a polynomial in a smooth solid line and then its integration to obtain the average value depths of the scratches, as shown in Figure (a) . For the pure UHMWPE [Figure (a,f) in DW and NS lubricating conditions, the depths of the scratches were about −5.19 and −5.89 μm in DW and NS, respectively.…”

Ultrahigh-molecular-weight polyethylene (UHMWPE) and UHMWPE composites reinforced with graphene oxide (GO) were successfully fabricated through a new step of liquid-phase ultrasonic dispersion, high-speed ball-mill mixing, and hot-pressing molding technology. When the GO/UHMWPE composites were lubricated with deionized water (DW) and normal saline (NS) solution, their friction and wear properties were investigated through sliding against ZrO 2 . The worn surface and wear volume losses of these composites were studied with scanning electron microscopy, X-ray photoelectron spectroscopy, and a Micro-XAM 3D noncontact surface profiler. The results show that the microhardness of the GO/UHMWPE composites was improved by 13.80% and the wear rates were decreased by 19.86 and 21.13%, whereas the depths of the scratches were decreased by 22.93 and 23.77% in DW and NS lubricating conditions, respectively.
