Analysis of Manufacturing Techniques on Strength Properties of Glass Fibre Reinforced Composites to be used in Automobile

In recent era the demands of Fiber Reinforced Composite materials are increasing because overall properties of the composites are superior to those of individual materials. Composites materials are used in almost all aspects of the industrial and commercial fields. Glass Fiber Reinforced Composites are considered to have potential use as a reinforcing material in polymer based composites. Glass Fiber Reinforced Composites have been prepared by various manufacturing technology and are widely used for various applications. Glass fibers are having excellent properties like high strength, flexibility, stiffness and resistance to chemical harm. Glass Fiber Reinforced Composite structures are manufactured by using E-class glass fibre and polyester resin using two different methods - hand lay-up and spray-up manufacturing techniques in the application area of car bumper for passenger cars. The specimens prepared from composite laminates are tested for mechanical properties such as tensile strength, flexural strength and impact strength as per the ASTM standard D638, D790 and D256 respectively. Results show improved strengths for spray-up method.
