Invite you to consult. | 11 Textile-reinforced composite materials Stephen L Ogin School of Mechanical and Materials Engineering University of Surrey Guildford GU2 7XH UK Composite materials Textile-reinforced composite materials TRCM are part of the general class of engineering materials called composite materials. It is usual to divide all engineering materials into four classes metals polymers ceramics and composites. A rigorous definition of composite materials is difficult to achieve because the first three classes of homogeneous materials are sometimes heterogeneous at submicron dimensions . precipitates in metals . A useful working definition is to say that composite materials are characterised by being multiphase materials within which the phase distribution and geometry has been deliberately tailored to optimise one or more This is clearly an appropriate definition for textile-reinforced composites for which there is one phase called the matrix reinforced by a fibrous reinforcement in the form of a textile. In principle there are as many combinations of fibre and matrix available for textile-reinforced composites as there are available for the general class of composite materials. In addition to a wide choice of materials there is the added factor of the manufacturing route to consider because a valued feature of composite materials is the ability to manufacture the article at the same time as the material itself is being processed. This feature contrasts with the other classes of engineering materials where it is usual for the material to be produced first . steel sheet followed by the forming of the desired shape. The full range of possibilities for composite materials is very large. In terms of reinforcements we must include S-glass R-glass a wide range of carbon fibres boron fibres ceramic fibres . alumina silicon carbide and aramid fibres and recognise that the reinforcement can come in the form of long or continuous fibres short fibres disks or .
