Fibre reinforced polymer composites properties

Tensile strength is the maximum stress that a material can withstand without tearing apart. It is a measurement of the ability of a material to withstand forces that tend to pull it apart. Tensile strength is measured in unit of force per unit area. Tensile properties of fibre reinforced polymer composites (FRPCs) can be determined according to ASTM D638 or according to... 

In the case of natural fibre reinforced polymer composites,in 1996 this material was used for making aeroplane seats and fuel tanks. The last decade has been used widely because of biodegradability and high specific properties. Currently, nanobiofibre composites are also provided for material revolution in technical application which is taking place in the automobile and packaging industrial.

Therefore, the first and the most important problem is the fibre-matrix adhesion. The role of the matrix in a fibre-reinforced composite is to transfer the load to the stiff fibres through shear stresses at the interface. This process requires a good bond between the polymeric matrix and the fibres. Poor adhesion at the interface means that the full capabilities of the composite cannot be exploited and leaves it vulnerable to environmental attacks that may weaken it, thus reducing its life span. Insufficient adhesion between hydrophobic polymers and hydrophilic fibres result in poor mechanical properties of the natural fibre-reinforced polymer composites. Pre-treatments of the natural fibre can clean the fibre surface. 

Natural fibre-reinforced polymer composites are considered as replacement for metals or carbons in situations where they have better mechanical properties. But the thermal properties of these composites are in general much lower than that of metals. Consequently, it is more difficult to dissipate the heat, and in some situations this can be an important consideration, particularly if electronic components...

The benefits offered by fibre-reinforced composites vary depending on the choice of resin, fibre and manufacturing process. Therefore there is a strong need to optimize the design of the composite since not all of the best properties can be achieved at the same time. By way of summary, the main advantages of fibre-reinforced polymer composites are usually oue or more of the following ...

The theme of the twelve chapters which comprise this book is information which can be used for designing a fibre composite article or structure. The data cover a wide range. There is information on the short- and long-term thermomechanical and electrical properties and behaviour of fibre-reinforced polymer composites, plus their response to fire and environmental effects. Finally the influence of processing on properties and the quality assurance of the final product are also considered. 

The performance of natural fibre reinforced polymer composites depends on several factors, including fibre chemical composition, cell dimensions, microfibrillar angle, defects, structure, physical and mechanical properties, and the interaction of a fibre with the polymeric matrix [28]. The knowledge about the characteristics of the fibre is essential in order to expand the effective use of lignocellulosic materials for polyethylene composites and to improve their performance. 

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.

The EUROCOMP Design Code is mainly concerned with glass fibre reinforced thermosetting polymer composites. Properties of the basic materials are given in Chapter 3 and of typical composites in Chapter 4. This section of the EUROCOMP Handbook will therefore deal primarily with those composites. However, it is desirable that the composite be compared with some of the alternative options that are available.

Bacterial cellulose-modified sisal and hemp fibres have also been used to produce unidirectional natural fibre reinforced CAB and polylactide (PLLA) model composites [9]. The mechanical properties of bacterial cellulose-coated sisal fibre reinforced polymers showed significant improvements over neat polymers (Table 6.8). The tensile strength and modulus for sisal/PLLA composites improved by as much as 68 and 49%, respectively. However, improvements were...
