Particulate composites, analysis techniques and applications

Abstract

The combination of at least two of the metal, ceramic or polymer groups at a macro level is called a composite material and, in this way, better properties are obtained. Composites can be partitioned into three groupings as layered, fiber and particle reinforced. Particulate composites offer flexibility in composition and component design and are isotropic. This investigation critically examines analysis techniques for particulate composites such as dimensional measurements, property distribution, composition and phase tests, density, and porosity tests (e.g. Archimedes, Pycnometer), hardness measurements (e.g. Brinell, Rockwell), mechanical properties through non-destructive and destructive testing (e.g. tensile, impact). In addition, application areas of particulate composites are highlighted, including Al-SiC composites for aircrafts, cemented carbides for tool metals, dental porcelain, electrical contacts, friction products, and thermal materials.
