Abstract:
1. A plastics composite, which comprises a) a hard component having a modulus of elasticity greater than or equal to 1000 MPa, wherein the hard component comprises a first conductive additive, the first conductive additive being selected from the group consisting of metals, metallized carbon, conductive plastics, and metallized fillers, the hard component further comprising a thermoplastic selected from the group consisting of polyacetal, polyamide, polyester, and combinations thereof, the first conductive additive comprising long conductive fibers having fiber lengths greater than 0.3 microns, the conductive additive being present in the hard component in an amount from about 5% to about 70% by weight and b) a soft component having a modulus of elasticity less than or equal to 500 MPa, wherein the soft component comprises a second conductive additive, the second conductive additive being selected from the group consisting of metals, metallized carbon, conductive plastics, and metallized fillers, the soft component further comprising a thermoplastic elastomer selected from the group consisting of polyolefin elastomers, polyetherester elastomers, polyesterester elastomers, polyether urethane elastomers, polyester urethane elastomers, polyetheramide elastomers, styrene elastomers, or combinations thereof, wherein the electrical conductivity of the composite is greater than 1 S/cm and the surface conductivity on at least one surface of the composite is greater than 0.1 S, and wherein the hard and the soft component have been connected to one another via an undercut or adhesion in such a way that the bond strength of the composite is at least 0.5 N/mm
