Friction and Wear of Potassium Titanate Whisker Filled Carbon Fabric/Phenolic Polymer Composites

Abstract

Carbon fabric/phenolic composites modified with potassium titanate whisker (PTW) were prepared by a dip-coating and hot-press molding technique, and the tribological properties of the resulting composites were investigated systematically using a ring-on-block arrangement under different sliding conditions. Experimental results showed that the optimal PTW significantly decreased the wear-rate. The worn surfaces of the composites and the transfer film formed on the counterpart steel ring were examined by scanning electron microscopy (SEM) to reveal the wear mechanisms. The transfer films formed on the counterpart surfaces made contributions to the improvement of the tribological behavior of the carbon fabric composites. The friction and wear of the filled carbon fabric composites was significantly dependent on the sliding conditions. It is observed that the wear-rate increased with increasing applied load and sliding speeds.

Tribological Behaviour of Short Carbon Fiber Reinforced Polyethersulfone Composites with PTW Filler

“…This made the polymer phase at contact asperities to transit from rigid state to rubbery state and sticking of the polymer phase on the sliding surface was observed. Due to the plasticizing of polymer phase on to the sliding surface, frictional force increased and resulted in increase in coefficient of friction and wear, indicating the strong influence of contact temperature on frictional behaviour of polymer composites [14]. Furthermore, Tb response of the filled composites was strongly influenced due to the linear effect of load, velocity and composites sequentially as seen in Table 10.…”

“…% in PTFE/PEEK composites and observed that coefficient of friction of the PTW series was slightly lower than that of the GF series at the same additive ratio, while the wear rate was the opposite, indicating that the wear resistance of GF was better than PTW [10]. PTW enhanced the mechanical strength as well as wear resistance of epoxy composites [11][12][13][14]. Tribological and mechanical performance of PTFE/PEEK composites filled with un-modified and modified PTW with n-octadecyltrichlorosilane were comparatively studied and reported that modified PTW showed higher wear resistance than the unfilled ones [15].…”

“…As they are less examined, there are more open points still to explore in thermoset plastics. There are many thermoset plastic resins available to the research community to investigate [2][3][4][5]. Among all resins, Epoxy is widely studied.…”

Optimization of friction properties of kenaf polymer composite as an alternative friction material

“…The new environmental regulations boosted the demand for natural fibre composites (NFC), thereby leading scientists and technologists to improve many of the NFC inherent drawbacks (Ahmad et al , 2015; Meon et al , 2012; Unal et al , 2014; Wambua et al , 2003; Zhang et al , 2015). However, the hydrophilic, heterogeneous and low-temperature processing compromised the mechanical properties and tribological performance of these composites and affected their use in automotive components (John and Thomas, 2008).…”
