A method of manufacturing a composite material, the method comprising: providing a first layer (14) of CNTs reinforcement elements (13) with liquid matrix material in interstitial gaps between the reinforcement elements; dipping a second layer of reinforcement elements into the liquid matrix material in the interstitial gaps such that the reinforcement elements in the second layer become partially embedded in the first layer of reinforcement elements and partially protrude from the first layer of reinforcement elements, impregnating the protruding parts of the reinforcement elements in the second layer with liquid matrix material; and curing the liquid matrix material.
