Unit 1
Types of reinforcements, their mechanical properties and functions – ceramics, glass, carbon, boron, silicon carbide, metal, aramid. Forms of reinforcements – particulate, fibre, filaments, whiskers, flakes. Pre-fabricated forms – preforms, prepegs, fabrics, honeycomb.
Type of matrix, its mechanical properties and functions – polymers (thermosets and thermoplastics), metals, ceramics, glass and carbon. Basic principles in the design of composites and selection of matrix and reinforcement. Bonding mechanisms.
