Good Agreement

The rule of mixtures was modified based on the concept of effective fibre volume fraction. The degradation parameter of effective fibre volume fraction was proposed in consideration of the microgeometry of composite components. It was shown that the modified rule has good agreement with the experimental strength data and the degradation parameter of effective fibre volume fraction used in this study can be used on general composites.

Natural fibres offer environmental benefits such as biodegradable and can be obtained from renewable resources. However, there is lack of investigations done to characterize and compare different types and orientation done on the natural fibres. This paper determines the tensile strength of sugar palm fibres under various treatment processes. The composites were fabricated using woven sugar-palm fibre treated with alkali and acid and used epoxy resin as the matrices for the composite. The tensile test was done to determine the tensile strength of the composite and the surface morphological analysis was done using SEM. The results demonstrated that the composite with the alkali treated fibres produced higher tensile strength compared to untreated and acid treated fibres. With these properties, it shows that treated woven sugar-palm fibre composite can withstand high stress load during operation compared to untreated fibres reinforced composites.

Strength And Toughness

The composite materials are replacing the traditional materials, because of its superior properties such as high tensile strength, low thermal expansion, high strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. Fiber composites such as Glass-Fiber Reinforced Polymers (GFRP) composites and Carbon-Fiber Reinforced Composites (CFRP) became more attractive due to their better properties for marine applications. In this paper, GFRP, CFRP and Hybrid composites are developed and their mechanical properties such as Hardness, tensile strength, compression strength, impact strength, toughness are evaluated. The study used to compare the effect volumetric fraction of fibers in order to improve strength and toughness, this done by using two types of fibers E-glass and carbon & two types of resins epoxy     ( AralditeLY556 and Aradur HY951 ) and vinyl ester. In this experimental study, we found that high tensile strength, high specific strength, hardness and low density are obtained with carbon fibre reinforced composites, but high impact strength and toughness are obtained with glass fibre reinforced composites. Finally incorporate the result and try to find alternatives composites using for marine applications and obtain the best mechanical properties

Fibre Reinforced Composites

ABSTRACTThe effect of the combined chemical treatment of sisal fibres through the subsequent processes of mercerisation (alkali-treatment), then silane treatment and eventually acid hydrolysis, on sisal fibre were investigated. The effect of the treated fibres on the tensile strength and stiffness, flexural strength and stiffness, compression strength and shear strength of their composites with epoxy resin were also studied. Scanning electron microscopy studies of the surfaces of the treated and untreated fibres showed that the chemical treatment processes enhanced the removal of surface extractives and therefore increased the roughness of the surfaces of the fibres in the range of 20 % - 70 %. This avails an increased reinforcement surface area for interlocking with matrix and is, therefore, expected to enhance adhesion of the two. The treated fibre reinforced composites were observed to have higher values of tensile strength and stiffness, flexural strength and stiffness, compression strength and shear strength than the un-treated fibre reinforced composites. These higher values were attributed to better interfacial bonding due to better mechanical interlocking between the treated fibres and epoxy resin arising from the increased roughness of the treated fibres.
