Abstract

Nowadays, there are abundant of carbon fiber reinforced polymer (CFRP) wastes, especially in the automotive industries, which lead to environmental pollution. In order to overcome the problem, the CFRP was reused as recycle material. In this research, the effect of chemical modification on tensile properties of thermoplastic reinforced CFRP waste was studied. The objectives of this research are to evaluate the mechanical, physical and thermal properties as well as to analyse surface morphology of polypropylene (PP) reinforced carbon fiber (CF). This research involves preparation of raw materials, surface treatment of recycled CF, fabrication of composite as well as testing and analysis of the final product. For surface treatment recycled CF, the CF was treated by using chemical modification to enhance their fiber-matrix interaction. For the composite fabrication, PP and CF were undergoing a mixing process in the internal mixer and hot pressing machine to produce a Polymer Matrix Composite (PMC) blend. The mechanical and physical testing that involved in this research were tensile and density, respectively. The morphology was observed by using Scanning Electron Microscopy (SEM). Furthermore, thermal analysis was conducted by using Differential Scanning Calorimetry (DSC). While, Fourier Transform Infrared Spectroscopy (FTIR) was used for identifying types of chemical bonds (functional groups). It was observed, composite with chemical surface modification produced better mechanical properties than composite without chemical surface modification regarding to its higher interfacial interaction of fiber-matrix.
