The pneumatically operated compression molding machine for initial cost of machine is low and the maintenance cost is polymer composites. The main aim of fabricating this machine minimal. is to prepare the fiber reinforced polymer composite samples Compression molding machine is used to prepare the for testing purpose. Researchers working on composites for FRP composite samples for testing purpose. In this process, research work they require the samples of composites with the molding material, generally preheated by using heater different composition for the purpose of testing. For that this after filling in a heated mold cavity. The mold is closed with machine is useful for the researchers and also for the the help of a top force, by using hydraulic cylinder and manufacturer to produce small sized less complicated plastic pressure is applied to force the material into contact with all components. In this machine temperature of specimen dies can mold areas. Heat and pressure is maintained until the be controlled automatically by using sensors and by using FRL molding material has cured. (filter, regulator and lubricator) unit, the pressure can be controlled. The low density, high strength and high stiffness to Compression molding is a method suitable for molding weight ratio, fiber reinforced composite materials are complex, high-strength fiber reinforcements. It is one of the manufactured by this machine are low cost. lowest cost molding methods compared with transfer molding and injection molding; In this research work, the tensile strength of test specimen of Epoxy without Fiber, Epoxy with carbon fiber, and Epoxy with 2. METHOD coconut fiber are tested and compared. Compression molding is a technique to develop variety of Key Words: Carbon fiber, Epoxy Resin, Fiber reinforced composite products. In this method, as shown in figure 1, Composite, Compression Moulding, and Test Specimen two matched metal dies are used to fabricate composite product by the application of compressive force. In this, 1. INTRODUCTION lower or bottom plate is stationary while upper plate is movable. Reinforce element (Carbon Fiber) and matrix Compression moulding process is done in two steps, (Epoxy) are placed in the lower die. Heat and pressure is preheating and pressurizing. Compression molding is a one applied as per the requirement of composite for a definite of the well known oldest technique used to develop variety period of time. Due to application of pressure and heat, the of composite products. Because of its ability to develop material placed in a dies/moulds flows and acquires the variety of composite products, the process is versatile. It is a shape of the mold cavity. Curing of the composite may closed die moulding with high pressure application. This carried out either at room temperature or at some elevated process is suitable for small to medium size parts. temperature. After curing, mold is ejected and composite In industries, different types of moulding machines are product is extracted by dismantling split die for further used; Semi-automatic and Automatic The hydraulic machine processing. can be used in some applications where there is a
