A Review of Polymer Based Laminated Composites for Flexural and Shear Properties

Dr. Rathnakar.G, Dr. H K Shivanand

In this paper, a comprehensive literature review on the flexural and shear properties of polymer based laminated composites has been presented. Since their introduction, fiber reinforced polymer composites have become an important class of composite materials owing to their high specific strength and specific stiffness. Fibers reinforced polymer matrix composites are being used extensively in automotive and aerospace structures due to their superior specific properties, which translate into low fuel consumption, higher passenger capacity and decreased maintenance cost, for example. The use of composite materials was limited only to secondary aerospace structures but with the development of knowledge about these materials, their use in primary aerospace structures has increased. Mostly, aerospace structures are based on thermosetting polymer matrices. However, use of thermoplatics is increasing everyday due to the excellent properties they offer such as unlimited shelf life, storage without freezing, improved toughness, possibilities for recycling and above all the short cycle productivity
