The Fracture Behaviour of Carbon Fibre Reinforced Composites
Carbon fiber-epoxy resin composites containing up to 0. 80 Vf of unidirectionally disposed fibers have been developed with flexural moduli and strengths very close to the theoretical values. However, the fiber-matrix interface is relatively weak resulting in low interlaminar shear strength. Attempts to raise the shear strength have led to brittleness problems. The fracture behavior of a variety of fiber-resin systems has been studied in the flexural and shear modes under static and repeated loading (fatigue), and under sustained loading (creep). Mechanical test data is correlated with fracture mode and morphology.
