Abstract
Growing concern for the environment coupled with the increasing cost of petro-based resources and advancements in the fields of biotechnology, nanotechnology and materials science, and engineering has led to the development of green materials for various applications. Fly ash is a particulate waste by-product formed as a result of coal combustion in power plants. Worldwide, more than 65% of fly ash produced from coal power stations is disposed off in landfills and ash ponds. The recycling of fly ash has become an increasing concern in recent years due to increasing landfill costs and the current interest in sustainable development. The use of fly ash as a filler or reinforcement for composites is desirable from an environmental standpoint. Recently, fly ash was successfully used in metal matrix composites to reduce overall weight and these composites are successfully used in automotive and aerospace applications. The polymer matrix composites developed using fly ash can be used as low cost green friction materials. This study is a review on the tribological behavior of fly ash-based green friction composites to understand their usability for various automotive applications.
