Abstract

Nowadays, there are a lot of daily usage are manufacture using the carbon fibre. Carbon fibre have a lot of advantages such as light weight but high strength. These are why carbon fibre become more and more popular in the aerospace industry and automotive. However, the waste of the components that are based on carbon fibre increases by year as the carbon fibre demand increases. The current handling method of the waste carbon fibre are through landfill and incineration but it will bring negative impact to the environment. Recycling of the waste carbon fibre through pyrolysis can solve the problem of landfill or incineration and sustain the resources. The pyrolysis temperature has been optimized by previous study. After that, the reclaimed carbon fibre is then compressed with the other thermoplastic such as polypropylene to form a new composite by using the compression moulding. However, the wetting issue between the carbon fibre and the polypropylene influences the strength of the composites. The mechanical behaviour of the composite is then optimized by closely monitoring the compression processing parameter by using Design of Experiment (DOE). The parameter involved are the compression temperature, the holding time for it to solidify and also the percentage of the fibre loading of the composites. Finally, the composite are tested with tensile test to evaluate the tensile strength of the composites.
