“…Chand et al developed and investigated the tribological behavior of ultra‐high‐molecular‐weight polyethylene (UHMWPE) filled epoxy gradient composites and concluded that gradient distribution in UHMWPE/epoxy composite could be achieved by centrifugation. UHMWPE filled centrifuged sample showed about 1/11 times the length loss as compared to neat epoxy under sliding wear . The addition of TiO 2 particles in epoxy graded composites has a dramatic effect on the flexural strength, tensile modulus, and impact strength as compared with homogeneous composites.…”

This article presents the comparison of mechanical and dry sliding wear peculiarity of zinc oxide (ZnO)-filled polyester composites, fabricated by two different techniques. These two techniques are simple mechanical stirring and vertical centrifugal casting. ZnO filled polyester based homogeneous composites are fabricated by simple mechanical stirring technique whereas composites fabricated by vertical centrifugal casting technique are functionally graded materials (FGMs). Dry sliding wear tests are performed over a range of sliding velocity (1.57-3.66 m/s), normal load (10-30 N), filler content (0-20 wt%), and sliding distance (1000-3000 m) using a pin-on-disc apparatus. This study establishes that the FGMs exhibit superior mechanical properties (except tensile strength) and wear resistance as compared with homogeneous composites. Among all the fabricated composites, FGMs filled with 20 wt% ZnO filler has maximum hardness and flexural strength i.e. 70 HRL and 39 MPa, respectively. Compressive and impact strength is maximum for 10 wt% ZnO filled FGMs with 36 MPa and 1.3 J, respectively. The tensile strength of homogeneous composites is 21.7% higher as compared with FGMs for 10 wt% of ZnO filler loading. FGM filled with 20 wt% of ZnO filler has minimum specific wear rate of 0.33 3 10 25 mm 3

“…3 However, some weaknesses, such as a low surface hardness, poor creep resistance, and low heat distortion temperature, constrain the further application of UHMWPE; consequently, much attention has been focused on the modification of UHMWPE. [4][5][6] Because of the strong antioxidant properties, good wear resistance, good thermal stability, low coefficient of thermal expansion, high thermal conductivity, high hardness, and excellent resistance to chemical corrosion of nano silicon carbide (nano-SiC), [7][8][9] nano-SiC is widely used as a filler in polymer-based composites. Nano-SiC possesses a unique small size effect and surface and interface effects; these advantages can effectively improve the mechanical properties and heat resistance of the resin matrix.…”

Ultra‐high‐molecular‐weight polyethylene (UHMWPE)/nano silicon carbide (nano‐SiC) composites were prepared by compression molding. The effects of a coupling agent and the content of the filler on the filler dispersion and the mechanical and thermal properties of the composites were investigated. The results show that the mechanical properties of the composites first increased and then decreased with increasing SiC content. The macromolecular coupling agent exhibited a much better reinforcing effect than the small‐molecule coupling agent. The tensile strength of the composites with 3‐aminopropyltriethoxysilane (KH550), γ‐methacryloxypropyltrimethoxysilane (KH570), and silicone powders reached its maximum value when the silicon carbide (SiC) content was 3%. We found that a web of the UHMWPE/SiC/coupling agent was formed and played a significant role in improving the heat resistance of the composites. In addition, appropriate amounts of SiC could increase the crystallinity of UHMWPE via a process of heterogeneous nucleation. The comprehensive performance of the KH550/silicone/SiC/UHMWPE composites was the best. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…For example, to enhance the wear resistance property of epoxy resin, carbon fiber‐reinforced epoxy gradient composites were developed at different centrifugation speeds having 3 wt % of milled carbon fiber. Sample prepared at 900 rpm after the transition zone shows maximum wear resistance due to the presence of more number of carbon fibers 8. Additionally, using a solution‐cast route, the electroactive polymer membrane and platinum electrodes were fabricated onto the membrane through electroless plating.…”

In this article, a copper‐in‐polymer‐gradient composite film (CPGCF) was synthesized by electrochemical strategy via reducing a solvent‐swollen cathode film (SCF). The latex nanoparticles of a ternary copolymer including styrene, butyl acrylate, and acrylic acid structural units play the key role to form well‐graded copper distribution in this ternary copolymer matrix through the porous morphological structure developed by latex nanoparticle semimelt joining. The morphological structure along cross‐section of CPGCF includes three layers: (1) a dense copper layer in ternary copolymer matrix whose most outside was originally attached to cathode in electrochemical reactor, (2) a shrublike layer that grew from dense copper layer, and (3) a clear layer in which there is no obvious reduced copper phase whose most outside was originally contacted with liquid electrolyte medium in electrochemical reactor. As experimental aspects, the influences of emulsion polymerization conditions of ternary copolymer, predrying time and temperature of SCF, dc voltage in electrochemical reduction on CPGCF structure were investigated. © 2012 Wiley Periodicals, Inc.
