Abstract Recent advances in the sphere of materials engineering have seen the advent of a new generation of composite materials that have become a replacement for the traditional materials used in different industries over the years. The proven potential of composite technology to deliver in line with critical global trends in the aerospace, automobile, and marine industries has placed it on top of other materials in the market. As composite materials can be lightweight and durable, they score very highly on efficiency measures with desired engineering properties required. A careful and wise combination of matrices, reinforcements, and additives can be tailored for specific applications of the end product. Traditionally, most of the fillers were considered as additives, limiting their contribution to a composite only on reducing their cost. However, the diversity of applications and a broad spectrum of their usage has led to high demand for incorporating fillers in composite technology. In this perspective, the objective of this chapter is to explore the works of literature for providing information about the fillers concerning processing, functions, mechanical and tribological characteristics, environmental impact. Moreover, the recent advances and challenges in employing different types of fillers in different classes of composites have been briefly discussed. Keywords Fillers · Composites · Wear · Friction

1 Introduction “Filler is a solid material capable of changing the physical and chemical properties of materials by surface interaction or its lack thereof and by its own physical characteristics” (Wypych 2016). Fillers are used for diverse industrial applications all over the world based on the nature and needs of the application. These additive components are incorporated in a mixture to elevate the properties and reduce the cost of the composites. The fillers are commercially available in the form of gases, solids, and liquids. Based on the requirements of the material’s applications, the fillers are selected among the various available categories. These fillers not only reduce the cost of the composite but also improve the processing and mechanical behaviour of the composite. They serve for a variety of purposes in different industrial applications such as adhesives, agriculture, aerospace, appliances, automotiv
