Interface Tailoring in Carbon Fibres Reinforced Metal Matrix Composites

Abstract

: The fabrication of high perforn~ance metal matrix conlposites reqoires the optinlization of the interfacial bonding, which supposesa strict control of the reactivity and of the wettability between the matrix and the reinforcement, specially for materials produced by casting techniq~ues. In this stop, two methods are described consisting on the one hand, in the surface treatment of carbon fibres by a particular type of CVD and, on the other hand, in modifying the composition of the nlatrix. The two methods can be used either separately or in combination, sucessful tailoring of the interface being the result of thermodynanlic or kinetic effects.

Interaction between titanium and carbon at moderate temperatures

“…Experimental conditions were chosen in order to investigate an interfacial zone some hundreds of nanometres thick. Given the discussion and comparison of the derived diffusion parameters, microscopic observations and other results obtained on composites and reported elsewhere, a fibre protection may be proposed and a maximum temperature for composite use may be estimated [16].…”

“…[1][2][3][4][5] Furthermore, aside from its capability as an advanced semiconductor, SiC has interesting mechanical properties with a high hardness ͑the third hardest material after diamond and boron nitride͒ and is used in matrix composites. 6,7 Also, it is one of the best biocompatible materials. 8,9 Due to very close lattice parameters, SiC is a very promising substrate for the growth of III-V nitrides ͑which, unlike SiC, have a direct band gap͒, providing a large range of interesting applications in optoelectronics.…”
