Embodiment Construction

[0021] figure 1 An exemplary embodiment of a device according to the proposal for producing fiber-reinforced synthetic materials is shown. The proposed device has a conveying mechanism 1 for the continuous conveying of fiber webs 2 . The fiber fabric 2 is presently a thermoplastic powder-bonded fiber material and thus a fiber matrix semi-finished product, which is also referred to as a prepreg.

[0022] The proposed device likewise has a transverse deformation mechanism 3 with an adjustment device 4 for deforming the conveyed fiber web 2 into a predetermined theoretical profile 5 . Two such theoretical profiles 5 with respectively different cross-sections in Figure 5 shown in a and b. In addition, further processing steps can be carried out in the transverse deformation mechanism 3 .

[0023] The device according to the proposal is then characterized in that the adjusting device 4 can be adjusted for changing the cross-section of the theoretical profile 5 . This adjustab...

Abstract

The invention relates to an apparatus for producing fiber-reinforced plastic preforms, comprising a feeding arrangement (1) for continuously feeding a non-crimp fabric (2), and a transverse shaping arrangement (3) that includes a draping device (4) for shaping the fed non-crimp fabric (2) into a predefined desired profiled element (5). The apparatus is characterized in that the draping device (4) can be adjusted so as to be able to modify a cross-section of the desired profiled element (5). The invention further relates to a corresponding method for producing fiber-reinforced plastic preforms.

Description

technical field [0001] The invention relates to a device for producing preforms made of fiber-reinforced synthetic material according to the preamble of claim 1 and a device for producing preforms made of fiber-reinforced synthetic material according to the preamble of claim 15 . The method of making prefabs. Background technique [0002] Fiber-reinforced composites, to which glass-fiber-reinforced composites (GFK) and carbon-reinforced composites (CFK) belong first and foremost, are gaining momentum as a replacement for conventional structural materials made of metals such as steel or aluminum. greater meaning. The fiber-reinforced synthetic material here offers good strength and stiffness with simultaneously low weight. This makes sense for its use, in particular in the automotive sector, in wind turbines and especially in aircraft construction, wherein for example profiles made of fiber-reinforced synthetic material can be used as skeletons in passenger aircraft.
