Learn about how different materials like ceramics, polymers and composites have different properties with BBC Bitesize KS3 Science. Fibers may be in the form of "whiskers" of substances such as silicon carbide or aluminum oxide that are grown as single crystals and that therefore have fewer defects than the same substances in a bulk ceramic (Figure 5.6~. BBC - BITESIZE - Brief information on ceramics, polymers and composites. Many of the useful properties of polymers are in fact unique to polymers and are due to their long chain molecular structure. Polymers are strong and tough, and often flexible. Composite materials combine two or more materials. In a hybrid process known as overmoulding, a short-fibre filled thermoplastic compound is … L.
