BBC - BITESIZE - Brief information on ceramics, polymers and composites. 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. Composite materials combine two or more materials. You will have seen ceramic materials coated in a tough glaze in bathrooms. QQT for plenary. Ceramics, composites and polymers. Ceramics are hard and strong, but brittle. Explain that stuff - Overview with pictures and links. 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. Plates tend to break if dropped onto the floor. ceramics: plant pots, plates etc composites: bricks, kevlar Polymers: tights, plastic bags Preview. People have been making and using pottery for thousands of years. 10.3.3 Ceramics, Polymers & Composites samabrhms11 2020-02-07T12:56:28+00:00 Ceramics Due to their high melting points and resistance to stains, ceramics are used in kitchen and dinnerware.
