Glass-fibre reinforced polymer composite

Silanes are well recognized and very efficient coupling agents extensively used in composites and adhesive formulations. They have been successfully applied in inorganic filler reinforced polymer composites for years and extensively used for glass fibre reinforced polymer composites.In this chapter, only silane treatment is discussed in short which is as follows ... 

In the short term, replacing heavy steel components with materials such as high-strength steel, aluminium or glass fibre-reinforced polymer composites can decrease component weight by 10-60%.

Sisal was chosen for this work, because the fibres are relatively stiff [7], meaning the buckling and wrinkling in the composite is lower, and their shape is also much cylinder like, therefore getting the possibility to use micromechanical models, i.e. rule of mixtures, for glass fibre reinforced polymers to consider the reinforcement properties of sisal fibres. 

With environmental awareness, natural fibre reinforced polymer composites have been expanding their application in sectors such as the automotive, construction, and packaging industries as a replacement for inorganic fibre reinforced polymer composites. Currently, glass fibre is one of the most widely used fibres to reinforce polymers, which can give superior mechanical properties.

Subclass B2 is formed by the so-called structural composites, in which an outspoken mechanical reinforcement is given to the polymer. Subgroup B21 consists of blends of polymers with compatible anti-plasticizers subgroups B22 are the most important the fibre-reinforced polymer systems. The two components, the polymer matrix and the reinforcing fibbers or filaments (glass, ceramic, steel, textile, etc.) perform different functions the fibrous material carries the load, while the matrix distributes the load the fibbers act as crack stoppers, the matrix as impact-energy absorber and reinforcement connector. Interfacial bonding is the crucial problem. 

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.
