Tensile failure surface of a carbon fibre composite
This is from the region of the fracture surface which was in tension. The fibres show clean, brittle fracture surfaces (with no fibrillation or distortion and little distortion of the matrix) and have broken at varying lengths and hence some stick out while others have left holes in the matrix. This is indicative of fibre pull-out having occurred after an initial failure of the matrix, followed by failure of the fibres themselves. This is a toughening mechanism in fibre reinforced composites.
