Abstract

An improved theoretical analysis is presented for the fibre fragmentation test. The result of stress transfer is obtained for the axisymmetric cylindrical single fibre-matrix model in the presence of residual thermal stresses in both axial and radial directions. The interface debonding behaviour is studied in terms of fracture mechanics where the debonding lengths are considered to be different at two fibre ends. Numerical results of the distributions of fibre axial stress, fibre-matrix interfacial shear stress and the debonding length versus applied stress are given for a carbon fibre-epoxy matrix composite with known interfacial properties.
