The compressive strengths and failure mechanisms of laminated carbon matrix composites reinforced with unidirectional carbon fibers are investigated for various off-axis angles (θ) of the fiber with respect to the loading axis. The compressive strength and elastic modulus decrease with increasing θ. The failure mechanism involves delamination due to fiber buckling at θ=0°(mode I), shear sliding along the fiber direction at 10°≤θ≤45°(mode II), and shear sliding along the direction perpendicular to the fiber fiber at 55°≤θ≤90°(mode III). Although the compressive strength is dependent on θ, the calculated shear strength in the sliding direction has a constant value of 23 MPa for mode II and 7.5MPa for mode III. The sliding along the fiber direction is accompanied by some fiber buckling due to fiber misalignment, resulting in a higher shear strength for mode II than for mode III.
