Abstract:

The objective of this paper is toSuperior mechanical properties of composite materials such as high stiffness and strength to weight ratios, corrosive resistance and low coefficients of thermal expansion, caused it to be used increasingly in many areas of technology including marine, aerospace, automotive and others. To take advantage of full potential of composite materials, accurate models and design methods are required the most common structural elements are plates and shells. Laminated composites are one of the classifications of the composites which are used in structural elements like leaf springs, automobile drive shafts, and gears, and axles.An accurate understanding of their structural behaviour is required, such as the deflections, the through thickness distributions of stresses and strains, the large deflection behaviour and, of extreme importance for obtaining strong, reliable multi-layered structures. In general, the fibres in the composite materials can be of unidirectional and bidirectional. Here the focus is on unidirectional fibre composite materials. The fibres can be oriented in many ways i.e., 0, 10, 20,30,45,90 degrees etc., but the strength in each type will be different. Using the load-deflection graphs, the maximum load and flexural strength are calculated. The attention is to note the variation of flexural strength of a composite material with the variation of fibre orientation and comparing the results with practical results. Here the modelling of composite material with different fibre orientations is done in Ansys software and simulation is done on them and those results are compared with practical results.
