Abstract

In fibre-reinforced composites, reactions occurring at the fibre-matrix interface and affecting the structure and composition of the interfacial region are studied to control the mechanical properties of the composites. For both metal matrix composites (MMCs) and ceramic matrix composites (CMCs) the interfacial reactions were investigated in different types of materials with different mechanical behaviour by microstructural (high-voltage and high-resolution electron microscopy, HVEM and HREM) and microchemical (energy-dispersive X-ray spectroscqpy and electron energy loss spectroscopy, EDXS and EELS) studies. Their effect on the mechanical properties was studied by corresponding scanning electron microscope in situ deformation tests.
