Fibre reinforced plastic (FRP) composites are gaining a wide reeognition as an alternative to the traditional metallic materials in a variety of applieations. As a result a reasonable step is to understand the mechanics of composites and provide the designers and industry with the knowledge based on reliable data stemmed from extensive researeh. 

Man-made composites fall into three broad classes, depending on whether the main part of the composite, the matrix, is a polymer, a metal or a ceramic. Often, but not always, the composite combines materials from two classes, as in glass-fibre-reinforced plastics. However, the most widely used composite material, concrete, is a ceramic -ceramic composite. The most important classes of artificial composite are described below. The mechanical properties of composites are discussed in Section 10.4. Biological composites are very varied and will not be considered here. 

If concrete removal is not required or supplementary reinforcing bars cannot be used, external reinforcement can be applied. For instance, steel bars may be encased in a shotcrete layer or steel plates may be bonded onto the concrete surface. Recently, the use of steel plates has been substituted by fibre-reinforced plastics (F. R.P.), that are composite materials with glass, aramide or carbon fibres embedded in a polymeric matrix (usually an epoxy system). F. R.P. are available in the form of laminates or sheets that are bonded to the concrete surface using an epoxy adhesive [11]. They are typically used to improve the flexural and shear strength or to provide confinement to concrete subjected to compression. The...

Fibre reinforced materials are indeed very versatile. In addition to their use in primary load carrying structures, they have been used as repair materials for structural components made from composites and metals. This chapter highlights several examples which demonstrate the relative ease with which repair to structural components can be achieved with fibre reinforced plastics. It is also pointed out that, as with other materials, the designer of any repair scheme with reinforced plastics must be aware of the effects of the environment on the performance of the materials used. Although fibre reinforced plastics are used in corrosive environments, studies in the Gulf States have shown that severe temperature fluctuations can affect the performance of fibre reinforced plastics in a repair environment. 

This chapter first gives an overview of cellulose raw materials and their molecular and supermolecular structures. The principles of shaping cellulose into fibres, films, and nonwovens by means of solution techniques are then outlined followed by a section on properties and market applications of these materials. Derivatives of cellulose are presented with special emphasis on thermoplastic cellulose esters, typical plasticizers, and promising reinforcing materials. Finally, recent developments and future prospects of cellulose materials are reviewed as far as the above applications are concerned. This book does not cover the important applications of cellulose and ligno cellulose fibres for reinforcing thermoplastics, like wood plastic composites (WPC) and natural fibre reinforced plastics (NFRP), since in these cases cellulose does not substitute a thermoplastic. 

The performance of all Composite materials is dependent on the adhesion between the different phases. In this article, aspects relevant to carbon-fibre reinforced plastics are discussed. There is a parallel article on Fibre-matrix adhesion - glass fibres. A discussion of the fibre-matrix interface can be found in Fibre composites - introduction. 

The construction industry is using various kinds of composite materials such as fibre reinforced plastics (FRP), polymer concrete, polymer-asphalt, fibre reinforced polymer concrete, and so on.
