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.

Hybrid self-reinforced composite material

The present invention refers to a method for the preparation of a reinforced thermoset polymer composite, said thermoset polymer composite comprising coated fibers, the coating being used as a vehicle for the introduction of carbon nanotubes into the thermoset polymer, the preparation of said reinforced thermoset polymer composite comprising the following steps: &#x2014;providing fibers; &#x2014;preparing a coating comprising carbon nanotubes and a polymeric binder; &#x2014;applying said coating to said fibers to obtain coated fibers; &#x2014;impregnating said coated fibers with a precursor of a thermoset polymer and letting part of the carbon nanotubes transfer from the coating into the precursor of the thermoset polymer; &#x2014;curing said precursor containing the coated fibers and the transferred carbon nanotubes to achieve the reinforced thermoset polymer composite.

Method for the preparation of a reinforced thermoset polymer composite

The present invention relates to a method for manufacturing a three-dimensional textile product, characterized in that at least the pile thread of which is subjected to one or more of the following textile treatments: a) the textile thread is enveloped; b) several textile threads are added to the textile thread; c) the textile thread is structured by making use of at least one monofilament and at least one multifilament; d) the textile thread is structured by making use of at least one monofilament and at least one multifilament thread of thermoplastic fibres; e) each of the textile treatments mentioned in points a-d are performed under such circumstances that the textile thread is kept sufficiently flexible during a first textile treatment and can be stiffened in a subsequent treatment.
