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.

Friction And Wear Tests

The effects of hydrogen on friction and wear properties of Ti–6Al–4V alloy sliding against GCr15 steel were investigated through dry sliding friction and wear tests in atmosphere at room temperature. Wear mechanism was determined by studying the morphology and chemical element of worn surface using SEM and EDS. Results show that friction coefficient decreases slightly and wear rate increases after hydrogenation. Wear mechanism is discussed.

Friction And Wear Properties

The effects of PTFE on the tensile and tribological properties of glass fiber reinforced polyamide 6(PA6) composites were studied. Tribological tests were conducted on an M2000 friction and wear tester using a block-on-ring arrangement. It was observed that the PTFE played a main role in the tensile-resistant and wear-resistant properties of the PA6 composites. The tensile properties were ruled by the fiber–matrix adhesion. And the excellent tribological performance of the PTFE fillers improved the tribological properties of PA6 composites.

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.

Asbestos-free frictional material is developed by using phenol formaldehyde resins modified with nano- SiO2 as matrix while surface-treated sisal fiber and glass fiber are used as reinforcement. The friction and wear properties were investigated on Constant speed (D-SM) tester. The abrasion surfaces of composites were observed by scanning electron microscope (SEM). Test result shows that all the properties, such as, friction coefficient and wear can meet the GB5763-2008 requirement. When the sisal fiber and glass fiber hybrid ratio is 2:1, the composite has the high mechanical property, suitable and stable coefficient of friction and relatively low wearability especially at high temperature.
