Mechanical Properties of Compression Moulded Aggregate-Reinforced Thermoplastic Composite Scrap

Recycling of thermoplastic composites has drawn a considerable attention in the recent years. However, the main issue with recycled composites is their inferior mechanical properties compared to the virgin ones. In this present study, an alternative route to the traditional mechanical recycling tech...
