Mode I interlaminar fracture toughness is investigated for a carbon-fibre composite toughened by nanofibres grown on the woven fabric reinforcement. For a comparison, the same is studied for the normal (non-toughened) composite. The test data show that the nanofibres significantly increase the fracture toughness, in combination with epoxy or PPS resin. This improvement is attributed to a better fibre-matrix interface as well as to local reinforcement of the matrix by nanofibres.
