Claim 0:
1. A composite material for mechanical components of force and motion transmission comprising at least three constituents:
(i) at least 45% by weight of a substrate material in relation to the total weight of the composite material,
(ii) 3 to 20% by weight of a first fibrous reinforcing material in relation to the total weight of the composite material, and
(iii) 10 to 45% by weight of a second reinforcing material in relation to the total weight of the composite material, wherein, the first fibrous reinforcing material has a lower thermal expansion coefficient than the second reinforcing material and wherein the second reinforcing material has a lower electrical conductivity than the first fibrous reinforcing material and wherein the parts by weight of the constituents contained in the composite material add up to 100%, and wherein the first fibrous reinforcing material exhibits a thermal expansion of from −0.15×10−6/K to 2×10−6/K parallel to the direction of the fibers and the second reinforcing material has an electrical conductivity of 10−4 S/m or less.
