Mechanical properties of carbon fibers coated with refractory carbides

Composite materials of the aluminium — carbon system

“…Studies of shear strength under twisting demonstrated noticeable surface strengthening of carbon fibres [42], which is explained by closure of surface defects due to stable bonding of the coating with the carbon fibres ( Fig. 6.13).…”

“…42 Relationship between optimum carbide phase content in carbonaluminium and AI-Si system matrix alloy composition. accompanied by their concentration on the fibre surface and by a change in the component interaction kinetics.…”
