Problems solved by technology

In this case, the amount of resin injected separately cannot be precisely controlled, and especially cannot be adjusted in steps
Therefore, a high component quality cannot be achieved with this method
In addition there is said control cost
Furthermore, especially in the case of rather large preforms or components, the injection phase is time-consuming

Embodiment Construction

[0071] In the pultrusion method according to the invention or the pultrusion according to the invention for producing, in particular, profiled preforms or fiber composite plastic components (not shown in the figures) with cross-sectional parts extending at an angle to each other In an extrusion plant, at least one multi-layered semi-finished construction is conveyed by a distributor device 11 and fed to a forming device 12 .

[0072] In the pultrusion method according to the invention for producing profiled preforms, the semi-finished product that is supplied to the forming device 12 for producing profiled preforms is constructed from a plurality of planar dry fiber fabric layers or fabric layers 1, 3. Forming wherein an adhesive material is added for fixing the planar fiber webs to one another between the two dried fiber web layers or between the fiber web layers.

[0073] In a further pultrusion method according to the invention, in particular for the production of profiled ...

Abstract

Disclosed is a pultrusion method for producing a profiled preform or fiber composite-plastic component having cross-sectional portions that extend at an angle from each other from a plurality of semifinished products (1, 2, 3) in a quasi continuous process. Said method comprises the following steps: - in order to produce the preform, a dispenser (11) discharges at least one multilayer semifinished product arrangement (HA) that is a combination of several webs of reinforcing fiber layers of a semifinished product and at least one resin film (2), and said multilayer semifinished product arrangement (HA) is delivered to a shaping device (12); - the semifinished product arrangement is guided through a shaping device (12) in which at least one cross-sectional portion of the semifinished product arrangement is bent in order to form an angle section; - the semifinished product arrangement (HA3) is pressed in a pressing device (13); - after an optional hardening process and a cutting process, a longitudinal section of the preform or the component is removed. Also disclosed are a pressing device and a pultrusion system (P) for carrying out said method.

Description

technical field [0001] The invention relates to a method for producing profiled preforms and profiled fiber composite plastic components, a pultrusion plant and an extrusion device for carrying out the method. [0002] In particular, the invention relates to a pultrusion method for producing profiled preforms with cross-sectional sections extending at an angle to one another from a plurality of semi-finished products in a quasi-continuous process, and to a method for producing a preform in a quasi-continuous process Pultrusion process for producing profiled fiber composite plastic components with cross-sectional sections extending at an angle to one another from a plurality of semi-finished products. [0003] Furthermore, the invention relates in particular to a pultrusion plant for producing profiled preforms or fiber composite plastic (FVK) components from a plurality of semi-finished products with cross-sectional sections extending at an angle to one another, and a pultrusi...
