摘要
In the past, asbestos and copper were preferred as friction materials because they have good ability to dissipate heat, but have proven to be harmful to environment. Recently, more researches are focused on non-asbestos friction composite materials due to its non-toxicity and biodegradability. Despite synthetic fibre composites having eco-friendly nature, because of its cost and pollution most of the researchers show interest on natural fibre composites. Hence, there is a need to explore the analysis on the tribologicaal behaviour of composite materials. The aim of this review is to provide overview of literature survey on the tribological characteristics such as friction, wear and lubrication of both particulate reinforced composites and fibre reinforced composites. In addition, operating and material parameters that influence tribological behaviour are also explored. Results reveal that operating parameters like normal load, sliding velocity, sliding distance, temperature and material parameters like particle size, volume fraction, fibre orientation, fibre length, surface treatment and aspect ratio have a significant effect on tribo characteristics.
