In this work, TLCP and GF reinforced PP have been recycled and TLCP/PP demonstrates superior recyclability over GF/PP due to the generation of fibrils during mold filling steps. The fiber shortening has a major impact on mechanical properties of GF/PP, which is induced by repeated injection molding and grinding. The thermal properties of TLCP/PP and GF/PP have been analyzed by DSC. The results show that injection molding and grinding does not impact the glass transition temperature, melting temperature and crystallinity of recycled composites.In continuation of this work, the influence of mechanical recycling on rheological, thermal stability and thermo-mechanical properties will be analyzed in order to gain full understanding about the impact of recycling on the various properties of TLCP and GF composites.
