Abstract: A material based on fibre-reinforced materials such as carbon-fibre reinforced plastics, prepegs, towpregs, with at least one locally pre-treated polymer covering. The covering has a hardness gradient, that is, from harder to softer from the inside to the surface of the covering.

Abstract: A method for producing wound hollow profiles having variable curvatures and cross-sections. In this case, a core having at least one curvature or cross-sectional change is moved in a translatory manner relative to a system having at least a first and a second fibre feed which cause the formation of an axial fibre reinforcement and at least one first wound layer.
