Properties Of Composites

Glass fiber (GF)/epoxy (EP) composites added by carbon nanotubes (CNTs) were fabricated to investigate the effects of CNTs on the friction and wear properties of GF/EP composites. The surface of the CNTs was treated with acid mixtures to improve their dispersion in the GF/EP composites. The changes of surface properties of CNTs were investigated by using fourier transform infrared spectroscopy. Ring-on-block type wear tests were performed to evaluate the frictional properties of composites. Results show that CNTs after acid treatments can improve the wear resistance and reduce the friction coefficient of GF/EP composites more remarkably than CNTs. The surface fracture of the composite was observed by scanning electron microscope.

Abstract In the present investigation, the COOH-functionalized multi-walled carbon nanotubes (MWCNTs) having an outer diameter of 20–30 nm and length 1−2 μm were dispersed in four different grades of polyalphaolefins (PAOs; i.e., PAO 4, PAO 6, PAO 40, and PAO 100) at various concentrations (0.025, 0.05, 0.075, 0.10, and 0.15 wt%) to evaluate friction, anti-wear, and extreme pressure properties. The tribological test was conducted as per ASTM standard using four-ball tester. The test results showed that with the addition of MWCNTs, the friction and wear properties of PAOs had been improved significantly as compared to the base oils. It was also observed that MWCNTs exhibited excellent anti-wear properties than friction properties. The possible reasons for the improvement in friction and wear properties are discussed with the aid of various analytical tools.

Friction And Wear Properties

In this study, the effects of nano-[Formula: see text] and carbon nanotubes on the friction and wear properties of carbon-epoxy woven composites have been explored. The unfilled carbon fabric composites and carbon fabric composites filled with carbon nanotubes and nano-[Formula: see text] were fabricated by vacuum infusion process. The worn surfaces were examined and possible wear mechanisms of unfilled and filled carbon fabric composites were discussed. In addition, the friction coefficient curves of unfilled and filled carbon fabric composites were analyzed and compared. The experimental results showed that either of the two nano-particles improved the friction coefficient and wear rate of carbon fabric composites; however, better improvement was observed for nano-SiO2. By adding these nano-particles to unfilled carbon fabric composites, a primary steady-state period with a low friction coefficient appeared in the friction coefficient curve of the composites, which indicates enhancement in bonding strength between carbon fiber and epoxy matrix due to the interfacial reinforcing action of the nano-particles.
