1 Composites Carbon Fibre KING SWAN ENGINEERING Date The industrial global now is full of materials or composites that contribute strongly to improve the quality and strength of the devices on all industries , and this can be increase the time period of it to be high efficiency And more comfortable for the manufacturers then the users . So, Priefly this report will discuss some important points about composites . This report discusses the composite materials and specially carbon fibre reinforced polymer and put it into comparing between other traditional metallic composites . There is many issues that the report concentrate on it, like the advantages of carbon fibre and how it so common at so much industries now

2 Composit es Composite is a thing made up of several parts or elements. 0 1 Composites 0 2 Carbon fibre composites compared with traditional 0 3 The Competitive Nature of 1. Composites A composite material is composed primarily of a matrix, i.e. a continuous phase, which is armoured with a reinforcement (reinforcement is a secondary phase), which is usually the discontinuous phase .

Fibre Reinforcement : Fibers are bigger than the same compact (dense/thick) materials. Fibre strength depends mainly on its cross-section. When decreasing cross-section the fibre strength increases (due to applying the strengthening processes that depending on the degree of deformation). Fibers usually have a shape of circular cross-section and a diameter in a variety range. Fig 2 3

Polymeric fibers Fig 3 Fig 4 Polymeric fibers are usually designed for polymeric matrices. The disadvantage of the polymeric fibers is higher temperature sensitivity, else their poor wettability. That due to the low surface energy of the fibers and therefore they require modification of the surface (surface treatment). The basic properties of polymer fibers: low density medium-high strength low stiffness the negative coefficient of thermal expansion 4

2. Carbon fibre composites compared with traditional metallic materials. Carbon Fibre Reinforced Polymer Fig 5 Carbon Fibre Reinforced Polymer (CFRP) is a composite Polymer matrix reinforced with carbon fibres, which are very strong and light. In CFRP the reinforcement material is carbon fibre that provides the strength. The matrix is commonly a polymer resin like epoxy, which binds the reinforcement together.
