An Investigation of Interfacial Reactions in Metal Matrix Composites.

Abstract

The interfacial reaction between fibre and matrix materials was studied in G/Al and FP/Mg composite systems. An intermediate layer of reaction product was necessary to prevent debonding in G/Al composites during cooling from the fabrication temperature. The intermediate layer was identified as the spinel MgAl2O4 in the FP/Mg composite and the effect of this intermediate layer was to provide good bonding and load transfer from matrix to fibre and also to form bridges (necks) cross-linking the fibres. The spinel also acted as a diffusion barrier to reduce the role of fibre degradation by interfacial reaction at service temperatures. (Author)
