Abstract

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.

Abstract

The diverse shapes in which vapour grown carbon fibres can be produced were studied using scanning electron microscopy and laser diffraction. Fibres with a cylindrical shape were characterised by tensile testing. It is shown that the Weibull distribution function is well adapted to interpret the fibres' strength data. On the other hand, the fragmentation method cannot be used to assess the quality of the interface of these fibres in polymeric matrix composites. This is due to the failure mode which is inherent to the inner structure of the vapour grown carbon fibres. © 1997 Elsevier Science Ltd.
