摘要

Procedure of treatment of vegetable fibers (I) to include as a reinforcement in a composite material containing base polymer comprises grafting on a nitrile or amide group of (I). An independent claim is also included for: (1) manufacture of a composite material containing polyamides or polyacrylonitrile bases including fibers treated by the procedure, comprising introduction of the fibers at a rate of 10-70% in the polyamide matrix; and (2) manufacture of a composite material to acrylonitrile butadiene styrene bases including fibers treated by the procedure, comprising introduction of the fibers at a rate of 10-70% in the arylonitrile butadiene styrene base matrix.
