Abstract
The present invention provides novel hybrid self-reinforced composites, combining an oriented brittle fibre and an oriented thermoplastic polymeric ductile fibre (as reinforcement phase) in the same thermoplastic polymeric matrix phase. The hybrid self-reinforced composites are strong and stiff, but in case of impact or crash they have high strain to failure and absorb a lot of energy. The present invention also relates to methods to produce said hybrid self-reinforced composites by a hot compaction technique.
