METHOD TO PRODUCE A COMPOSITE SEMI-FINISHED PRODUCT

摘要

Method for producing a composite semifinished product (1), with a continuous phase comprising at least one thermoplastic material (2) and a disperse phase consisting of at least one electrically conductive filler (3), wherein the at least one thermoplastic material is mixed in the form of fine particles with the at least one filler in the form of fine particles, wherein in each case at least 90% by weight of the particles of the at least one thermoplastic material and of the at least one filler are smaller than 1 mm, in which method the mixture (4) of the at least one thermoplastic material and the at least one filler is heated up to a temperature which is greater than the melting temperature of the at least one thermoplastic material, and in which method the heated material is cooled to a temperature below the solidification temperature of the at least one thermoplastic material.
