Abstract

Carbon fibre is one of the composite materials used in the aerospace industry. The usage of carbon fibre in production of the aeroplane can reduce the weight while maintaining the high durability of the material. The high durability is a crucial characteristic that needs to be consistent in the material in order to withstand the high pressure while the aeroplane is flying high in the sky. The main objective of this project is to find the optimum design of composite that has the maximum strength by using the design of experiment. Before achieving this objective, the carbon fibre specimens are produced by using the resin infusion method. The two variables that are manipulated in this experiment are the number of ply and the orientation of the carbon fibre. Then, the specimens undergo tensile testing by using the universal testing machine in order to obtain the tensile strength of each specimen. Furthermore, analysis was done based on the output data obtained to find the optimized combination of factors by using the design of experiment method obtained from the Design Expert software. The result shows that the optimized model for maximising the tensile strength of the carbon fibre is the design with high number of ply and low degree of orientation.
