polymers: Thermosetting and thermoplastic polymers, properties of polymers like epoxies, 2 1.1 WHATARE “COMPOSITES? • Composite: Two or more chemically different constituents combined macroscop... ically to yield a useful material. • Examples of naturally occurring composites permeated with holes filled with liquids ➢ Wood: Cellulose fibers bound by lignin matrix ➢ Bone: Stiff mineral “fibers” in a soft organic matrix permeated with holes filled with liquids ➢ Granite: Granular composite of quartz, feldspar,and mica. • A composite material is made by combining two or more materials– often ones that have very different properties. • The two materials work together to give the composite unique properties. • However, within the composite you can easily tell the different materials apart as they do not dissolve or blend into each other. ➢ Composite materials are materials made from two or more constituent materials with significantly different properties, that when combined, produce a material with characteristics different from the individual components. ➢ Composite materials consist of two or more chemically distinct constituent on a macro scale having a dispersed interface separating them and having bulk performance which is considerably different from those of any of its individual constituents. 3 Examples:- Cement, Concrete, Fiber-reinforced polymer, etc. • Some examples of man‐made composites – Concrete: Particulate composite of aggregates (limestone or granite), sand, cement and water – Plywood: Several layers of wood veneer glued together – Fiberglass: Plastic matrix reinforced by glassfibers – Cemets: Ceramic and metal composites – Fibrous composites: Variety of fibers (glass, kevlar, graphite, nylon, etc.) bound together by a polymeric matrix [Show More]
