Composites are an important material in an intensely competitive global market. New materials and technologies are being produced frequently for

the design and rapid manufacture of high-quality composite products. Composites are replacing more traditional materials as they can be created with properties specifically designed for the intended application. Carbon fibre has played an important part in weight reduction for vehicles and aircraft.

• Form: fibres/sheet/particles and matrix

• Process: weaving, moulding, pultrusion and lamination

• Composition and structure of composites: concrete, engineered wood, plywood, particleboard, fibreglass, Kevlar®, carbon-reinforced plastic, laminated veneer lumber (LVL)

• Fibres/sheets/particles: textiles, glass, plastics and carbon

• Matrix: thermoplastics, thermosetting plastics, ceramics, metals

• Advantages and disadvantages of composite materials

• Design contexts in which different types of composite materials are used

As designers develop new products, they should always be aware of the materials available. In an effort to increase productivity and lose weight, carbon fibre parts are often glued together. The use of an epoxy adhesive rather than traditional fastening methods allows manufacturers to create complex shapes quickly and easily. These materials and methods are being transferred to consumer products.
