Ceramics are hard and strong, but brittle. QQT for plenary. Bitesize; Home. Thermoplastic composites are usually produced by commingling polymer fibres with reinforcing fibres and heating in a mould so the polymer melts to form the matrix. are solids made by baking a starting material in a very hot oven or kiln, Ceramic materials are used to make wall tiles, baths, sinks and toilets, They are strong under compression, so a house will not be crushed under its own weight, They are brittle, so the bricks can break if handled carelessly during construction, Bricks are strong and durable, making them ideal for building houses. Start your review of Engineering Materials: Polymers, Ceramics and Composites. diagrams and links. BBC - BITESIZE - Brief information on ceramics, polymers and composites. Ethene molecules join together to make long molecules of poly(ethene), Strong, hard-wearing, chemically unreactive, Can be made into fibres, strong and flexible, Can be made into fibres, very elastic and tough, Some polymers are hard and rigid, like the polymer used to make this electrical socket. Unfortunately, it makes polymers difficult to dispose of. These short films give more information about polymers, composites and ceramics. The ability for composites to withstand fire has been steadily improving over the years. Alloying metals improve their properties. Ceramics are hard and strong, but brittle. 4.8 12 customer reviews. Polymers are made by chemical reactions that join lots of small molecules together to make long molecules. Key stage: KS 3. Different materials have different properties. This is a useful property because it means that plastic bottles will not react with their contents. People have been making and using pottery for thousands of years. A comparison of four groups of materials. Read about our approach to external linking. Long molecules like these give polymers their properties. Difficulty level: Sign up to complete it for free In this chapter, focus will be on general characteristics, applications and an introduction to the mechanical behavior including elementary concepts of their inherent time dependent or viscoelastic nature.

Elastomer, any rubbery material composed of long chainlike molecules, or polymers, that are capable of recovering their original shape after being stretched to great extents—hence the name elastomer, from “elastic polymer.”Under normal conditions the long molecules making up an elastomeric material are irregularly coiled. For example, a molecule of poly(ethene) is made by joining thousands of ethene molecules together. Different materials have different properties. Explain that stuff - Overview with pictures and links. There is two types of systems to be considered: Fire Retardant - Are self extinguishing laminates, usually made with chlorinated resins and additives such as Antimony trioxide. Ceramics, polymers and composites have desirable properties that allows them specific uses. They do not rot away very quickly and they can cause litter problems. 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~.
