Abstract
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: —providing fibers; —preparing a coating comprising carbon nanotubes and a polymeric binder; —applying said coating to said fibers to obtain coated fibers; —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; —curing said precursor containing the coated fibers and the transferred carbon nanotubes to achieve the reinforced thermoset polymer composite.
