Regeneration Of Thermally Recycled Glass Fibre For Cost-Effective Composite Recycling : Performance of fibre recyclates from thermoset composites and with subsequent ReCoVeR treatments

摘要

This paper reported transformability of regenerating strengths of heat treated glass fibres (HTGFs) into recycled glass fibres (RGFs) from polyester composites at 500 to 600oC. The fibre recyclates were examined using scanning electron microscopic (SEM) and showed that the surface contains different types and amounts of thermal residues depending on treatment temperature. With additional washing step, the RGF surface is dramatically clean. The RGFs, with/without washing step, were further treated using ReCoVeR process, where strength of HTGFs can be recovered. The tensile results demonstrated that ReCoVeRed RGFs shows positive effect on strength enhancement but not as significant as HTGFs. However, higher strength was found on ReCoVeRed RGFs with additional washing step. The observation and discussion were detailed in this study.
