Problems solved by technology

However, the disadvantage of these pre-impregnated fibers is that the resulting semi-finished product can only be used for geometrically simple structures due to its nature, and also leads to a very high consumption of fiber material, because the pre-impregnated Cut to the desired profile or shape of the fiber composite part
As a result, a corresponding waste of fibers occurs, which makes the production of fiber composite components significantly more expensive when prepregs are used

Embodiment Construction

[0069] In principle, the method according to the invention can be based on figure 1 The diagram in the implementation. The fiber belt (1, 1', 1") is guided from the material storage place (2, 2', 2") to the pre-determined place via a pair of conveying rollers (3a, 3b; 3a', 3b'; 3c, 3c'). The processing station (7), optionally, can use guide rollers (8, 8', 8") to assist the conveying of the fiber belt (1, 1', 1"). In the pretreatment station (7), the fiber tape (1, 1', 1") is optionally prepared for the step of joining, for example, in the case of a fiber tape with a thermoplastic matrix, by heating and making the thermoplastic matrix at least partially The preparation is carried out by melting. Further, the fiber belt (1, 1', 1") is continuously conveyed from the pretreatment station (7) to the connection station (4). In the connecting station (4), the fiber belts (1, 1', 1") are connected by consolidation rollers (5, 5') to form a laminate (6). In the fiber belts (1, 1', 1")...

Abstract

The invention relates to a method for the continuous production of laminates made of at least two fibre bands made of fibres which are embedded unidirectionally in a plastic material matrix. Likewise, the invention relates to laminates which are produced in this way and can have a shape memory. The laminates according to the invention are used for local reinforcement of injection moulded parts.

Description

Technical field [0001] The present invention relates to a method for continuously manufacturing a laminate made of at least two fiber tapes made of fibers unidirectionally embedded in a plastic material matrix. The invention also relates to a laminate that is manufactured in this way and can have shape memory. The laminate according to the present invention is used for local reinforcement of injection molded parts. Background technique [0002] In lightweight constructions, especially in motor vehicle constructions, fiber-reinforced composite material components are increasingly used to carry structural components. For lightweight construction with fiber composite material components optimized for weight and cost, the use of cost-determining materials, especially fiber components, must be minimized. At present, it has been proposed to correctly integrate fibers with respect to the force flow in the component structure without fiber cutting. This is made possible by a variety o...
