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.

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 strip-shaped fiber-reinforced composite material has a fibrous structure that is impregnated with a matrix material which contains at least one thermoplastic polymer. At least one of the large faces of the strip-shaped fiber-reinforced composite material has surface shaping. The surface shaping contains at least one indentation which extends from one of the narrow longitudinal faces of the strip-shaped fiber-reinforced composite material continuously over at least 30% of the width of the strip-shaped fiber-reinforced composite material. Furthermore, a method is performed for producing the strip-shaped, fiber-reinforced composite material.

Abstract: A process for manufacturing bonded laid structures from yarns, characterized in that a thermally fusible material is applied to the yarns at least at the contact or intersection points via a thermal spray process and the yarns are subsequently brought together, as well as a process for manufacturing a fiber-reinforced composite material, characterized in that, initially, laid structures according to the invention are manufactured and subsequently, with the addition of further thermally fusible material if necessary, the structures are molded under heat and pressure into the fiber-reinforced composite material.
