Abstract

The invention relates to a composite material comprising a polyamide matrix and mineral fillers of submicron size. The filler used comprises at least one core and a surface layer for modifying its dispersibility in the matrix or in the medium for synthesizing the matrix. The filler allows the thermomechanical properties of the polyamide to be modified.
