Sample 1 had no phenomenon of pulling-out and debonding of fibres under vertical compression load and the interface bonding intensity is strong between the fibres and the matrix. The material shows brittle fracture: if σ(subscript ⊥)=60.7MPa. However, sample 1 has the phenomenon of fibres debonding because of the shearing stress between the fibres and the matrix under parallel compression load. The material shows tough fracture:σ(subscript ∥)=52.6 MPa.
