Fabrication of glass-polymer composite laminate with different angle ply orientation


K Sudheer Kumar, K Sudhakar Reddy, B Ramakrishna, Kameshwara Rao4

This work involves Fabrication of E-glass general polyester and Epoxy composite laminate with Different Angle Ply Orientation. Laminated Composite materials have characteristics of high modulus/weight and strength/weight ratios, excellent fatigue properties, and non-corroding behaviour. These advantages encourage the extensive application of composite materials, for example, in wind turbine blades, boat hulls, automobiles, water tanks, roofing, pipes and cladding, and aerospace. The understanding of the mechanical behaviour of composite materials is essential for their design and application. Although composite materials are often heterogeneous, they are presumed homogeneous from the viewpoint of macro mechanics and only the averaged apparent mechanical properties are considered. The most common method to determine these constants is static testing. In this work ten types of composite laminate specimens with different stacking sequences, i.e., (±00, ±100, ±300, ±400, ±450, ±550, ±650, ± 750, and ±900) are fabricated and specimens are prepared in the laboratory using compression mould technique E- glass as fibre & with Polyester resin and Epoxy as an adhesive. The specimens are prepared for testing as per ASTM standards to estimate the tensile modulus.
