|Summary||The aim of this research is to recycle waste of unsaturated polyester-based matrix composites reinforced with glass fibres, by grinding and incorporating it into a PP/PE copolymer matrix. Commercial glass fibres were gradually replaced by the ground waste in the composite until complete substitution was attained. Then, the new materials were mechanically tested. Results show a strong decrease in tensile strength and impact resistance. To improve the mechanical properties of composites, the incorporation of an interfacial agent was tested. For this purpose, four different weight contents of an interface agent were introduced. This additive noticeably improves the mechanical results of these new materials. The incorporation of 5% of interfacial agent is found to produce almost the same mechanical results as composites containing only commercial glass fibres.
