Recycling of Long Fibre Thermoplastic Composites by Low Shear Mixing
Continuous fibre reinforced thermoplastics have become increasingly popular, therefore a need for high quality recycling becomes more crucial. This study thus focusses on recycling post-industrial waste of Long Fibre Thermoplastic (LFT) dimensions into parts, with mechanical properties close to the original continuous fibre composite. A consolidated continuous E-Glass fibre polypropylene laminate is recycled to LFT material and compared to the virgin material and LFT pellets. Material is cut to flakes and processed by a small scale, low-cost and low-shear mixing machine and compression moulded. Mechanical properties match the theoretical model and are close to continuous fibre composites’ properties, when corrected for orientation.
