Abstract:
1. A method for the preparation of a composite material comprising the following steps: sintering an inorganic-nonmetallic starting material to obtain a sintered porous inorganic-nonmetallic matrix product; followed by coating the surface of the porous inorganic-nonmetallic matrix with a coupling agent to obtain a surface-modified product; infiltrating the surface-modified, porous inorganic-nonmetallic matrix with an organic material; followed by solidifying the organic material; to obtain an isotropic composite material comprising a porous inorganic-nonmetallic matrix having a bending strength greater than or equal to 40 MPa as measured according to ISO 6 872 and an organic material at least partly filling the pores of the porous inorganic-nonmetallic matrix, such that the isotropic composite material has (i) a modulus of elasticity greater than or equal to 25 GPa as measured according to ISO 10 477 and (ii) a bending strength greater than or equal to 100 MPa as measured according to ISO 6 872.
