Problems solved by technology

This requires a large installation space and often also requires a more complex control mechanism, since the individual suppliers have to coordinate with each other

Embodiment Construction

[0026]The drawing shows in a very simplified form a semi-finished web 1 with a longitudinal direction 2 indicated by an arrow and a plurality of fibers 3 fixed in a unidirectionally oriented manner. The fibers 3 run at a predetermined angle a relative to the longitudinal direction 2 . The fibers are embedded in a matrix (not shown in detail) made of plastic.

[0027] To produce such a semi-finished web, a stock web 4 is used. The supply web 4 can, for example, be unwound from a supply roll 5 . Optionally, several supply rolls 5 can also be arranged next to each other and correspondingly several supply webs 4 can be pulled down simultaneously. However, the supply web 4 can also be produced in-line. The supply web 4 can optionally also be removed in sections from a store or magazine.

[0028] As a stock web, for example, the semi-finished web described in EP 2 301 735 A2 can be used. The supply web 4 can therefore have a multiplicity of fibers 6 fixed in a unidirectional or...

Abstract

Described is a method for producing a semi-finished web (1). The semi-finished web (1) has a longitudinal direction (2), a plastic matrix and a lot of fibers (3) fixed in a unidirectionally oriented manner, the fibers (3) enclosing a predetermined angle (a) larger than 0 degree to the longitudinal direction. The method includes the following steps of applying a supply web (4) which has a main direction (7), a plastic matrix, and a lot of fibers (6) fixed in a unidirectionally oriented manner, the fibers (6) enclosing an angle of about 0 degree to the main direction; separating segments (8) from the supply web (4); arranging the separated segments (8) next to one another, so that longitudinal edges (9,10) of adjacent segments are parallel to the main direction (7) and to one another, and enclose the predetermined angle (a) to the longitudinal direction (2); and connecting the adjacent segments (8) in a region of their longitudinal edges (9,10).

Description

technical field [0001] The invention relates to a method for producing a semi-finished web. [0002] Furthermore, the invention relates to a device for producing semi-finished webs. Background technique [0003] Components made of fiber-reinforced plastics are used in many technical fields. Components made of fiber-reinforced plastic have the advantage of higher specific mechanical properties than components made of metal. In addition, plastics can also be used in areas where metals would corrode. [0004] EP 2 301 735 A2 shows a semi-finished product and a semi-finished composite as well as a production method for such a semi-finished product. In this case, the unidirectionally oriented fibers are arranged between two layers made of thermoplastic. This composite then forms a "sheet" which is deformable like a metal sheet. Such a semi-finished product has a higher tensile strength in the corresponding direction in which the fibers extend. In the direction transverse to...
