Process for the manufacture of thermoplastic composites with a matrix and a polymeric fibrillated reinforcing phase.

摘要

1. Composite materials comprising at least one first thermoplastic polymer as a matrix and at least one second crystalline polymer acting as a fibrous reinforcing phase, characterized in that the said first polymer is present at the rate of 60 to 98% by weight and is selected from polyphenylene sulfides, polycarbonates, polyamides, polymethylmethacrylate, polystyrene, polypropylene, polysulfone, polyvinyl chloride, polyethers, sulfone-polyethers, cetone-polyethers, polyacetals, polyurethanes, polyacrylonitrile, polyesters, acrylonitrile-butadiene-styrene and acrylonitrile-styrene copolymers, polyfluorophenylacrylate, polyfluoromethylacrylate and the second crystalline polymer is a fluorinated polymer which is present at the rate of 2 to 40% by weight and which is selected from polytetrafluoroethylene with a number average molecular weight Mn at least equal to 50 000 000, perfluorinated poly(ethylene/propylene), perfluoroalkoxy polymer and polyvinylidene fluoride.
