A method for production of carbon fibre - copper composites by foil casting is presented. As follows from the test results included, the foil casting process may be applied to produce the carbon fibre -copper composites. Thanks to the use continuous fibres, the method allows to obtain composites with fibres ordered directionally. Measurements of thermal expansion and micro-hardness of a composite with 30% fibre content, as well as examination of its microstructure are presented. The composites may, among others, find application in manufacturing of electrodes for resistance welding, electric contacts and expansion wafers for semiconductor power components.

Reinforced Thermoplastics

In recent years, carbon fibre reinforced thermoplastics (CFRTP) are expected to be used as lightweight structural materials for mass-produced vehicles. CFRTP with thermoplastics as matrix allows us to weld them using melting of matrix by heating. We have been developing a direct resistance heating method, which uses carbon fibres as the resistance heating element. Carbon nanotube (CNT) is expected to be used as additive to FRP and we reported that the fibre/matrix interfacial shear strength was improved by grafting CNT on the surface of carbon fibres and tensile lap-shear strength was improved by using CNT grafted carbon fibre as the heating element for welding. For the practical use of CFRTP for structural parts, flexural strength is also necessary to be evaluated. In this study, flexural test was carried out to clarify the effect of CNT deposition time to the surface of carbon fibres on flexural strength of resistance welded CFRTP using CNT grafted carbon fibre as the heating element. The highest flexural strength was obtained when CNT10, for which CNT is grafted on the carbon fibres for deposition time of 10 min, was used for the heating element of resistance welding. In the case of CNT deposition time of 60 min, the lowest flexural strength was obtained because of the poor impregnation of the resin into the carbon fibre due to the excess CNT on the carbon fibres.
