Summary

Fracture behaviors of [0°/90°] and [0°/90°/±45°] laminated carbon fiber reinforced carbon matrix composites (C/Cs) were compared. Both C/Cs showed linear deformation up to the total fracture in tensile tests. On the other hand, the [0°/90°] C/C showed strong nonlinear deformation in shear test, while the stress-strain relation of the [0°/90°/±45°] C/C in shear is linear. Fracture appearance of double-edge-notched (DEN) specimens of both C/Cs was similar tend. The relation between fracture toughness and crack advanced length of both C/Cs was observed to be nearly the same. This is the reason why both C/Cs exhibited the same fracture tendency in the DEN test. To understand underlying mechanisms, the toughness curves of both materials were examined in more detail by changing the notch root radius and the notch length.
