Article Preview

Copper matrix composite with pure copper matrix reinforced with high modulus carbon fibres Thornel K 1100 was prepared by gas pressure infiltration technique. As-received composite was subjected to thermal expansion and thermal conductivity measurements in longitudinal and transversal directions. Large anisotropy of properties as well as surprisingly good structural stability has been observed. The mean coefficients of thermal expansion as low as 0.8 x 10-6 K-1 in longitudinal and as high as 23.5 x 10-6 K-1 in transversal directions were determined, the thermal conductivities as high as 650 Wm-1K-1 in longitudinal direction and as low as 60.7 Wm-1K-1in transversal directions were measured.
