Embodiment Construction

[0020] exist figure 1 The outline of the bellows 2 is schematically shown in . The perforations 4 are also shown schematically, which are located in the wall of the bellows 2 . In the depicted exemplary embodiment, the bellows 2 is formed from a series of parallel ring-shaped formations. In the exemplary embodiment, rings with an angular cross-sectional profile are shown, but these rings can also have a rounded cross-sectional shape, for example a semi-circular or semi-elliptical shape.

[0021] When the matrix material flows through the bellows 2 in the longitudinal direction L, the matrix material can flow outwards through the perforations 4 . When the corrugated tube 2 is placed in a mold for producing a fiber composite component, the matrix material can penetrate through the perforations 4 after leaving the corrugated tube into the reinforcing fibers placed in the mold and fill the mold.

Abstract

The invention relates to a resin line with peripheral openings. In order to provide a resin line that can be produced inexpensively, that meets the static requirements under action of the vacuum, andthat enables a more precise discharge of the matrix material independent of the bending radii at which the resin line is laid, the resin line is formed of a corrugated pipe (2) whose wall comprises through openings (4).

Description

technical field [0001] The present invention relates to a resin tube with a peripheral side opening. Background technique [0002] A resin tube of this type is known from document DE 10 2014 011 787 A1. As the resin tube, a flexible spiral hose is disclosed in this document. The resin tube is inserted into a mold for the production of the fiber composite component in order to convey the liquid matrix material under vacuum to the reinforcing fibers inserted into the mold. These reinforcing fibers are available as rovings (Rovings), mats (Matten), lining yarns (Gelege), fabrics, multiaxial materials (Multiaxialmaterialien), knitted fabrics (Gewirke) and braided fabrics (Geflechte) as fiber half-costs and are made of various Fiber materials, such as carbon fibers, glass fibers, aramid fibers (Aramid fibers), boron fibers (Borfaser) or hybrid materials, can also be combined in any desired form. The reinforcing fibers are impregnated with the matrix material conveyed through t...
