Abstract
The micromechanical fracture behaviour of C/Mg-Al composites of varying interface reactivity was investigated by scanning electron microscope bending tests. Structure and chemistry of fibre/matrix interlayers were studied down to the atomic scale by imaging and spectroscopical transmission electron microscope techniques (high-resolution electron microscopy, energy dispersive X-ray spectroscopy, parallel-recording electron energy loss spectroscopy and energy-filtered transmission electron microscopy). The chemical reactions at the fibre/matrix interfaces of the C/Mg-Al composites were found to form plate-shaped carbidic precipitates, mainly Al2MgC2, which strongly influence the composite's mechanical properties by changing the fibre/matrix bonding strength.
