Problems solved by technology

[0005] Despite the clear advantages of this VAP method compared to the method using an autoclave, there is a certain problem that each individual layer of the planar material, i.e. the film, the spacer maintaining layer and the gas-impermeable foil, must be sequentially very precisely and Stress-free placement on top of semi-finished products
This is rather time-consuming and, if not done with great precision, can have a negative impact on process safety and can lead to uneven build-up of matrix material

Embodiment Construction

[0018] first with the help of figure 1 The device elaborates the VAP technique according to the prior art.

[0019] figure 1 The shown arrangement shows a component to be produced or a dry fiber composite semi-finished product 1 , which is arranged on a tool 3 , for example by means of a structure 5 . This component or laminate (Laminat) can here mean a plastic product made of carbon fibers (CFK), glass fibers (GFK), nylon fibers (AFK), boron fibers (BFK) or hybrid materials and is used in particular for the manufacture of Unreinforced and reinforced, large area trim panels, plastic tools or rod handles to repair damaged FVW components. The tool 3 has a suitable shape for receiving the semi-finished product 1 or, if necessary, the superstructure, and can consist of different suitable materials such as wood, steel, sheet metal, glass and the like.

[0020] This structure is covered with a semi-permeable membrane 7 which is gas permeable but prevents the penetration of the ma...

Abstract

The multilayer laminate for lining matrix feeders used in impregnation of preforms comprises a gas-permeable, matrix-impermeable inner sheet (41) and a gas-impermeable outer sheet (44). These are separated by a layer (43) of gas-permeable spacers (45). These hold the sheets in position when a vacuum is applied between them. A textile layer (42) is laminated to the outer surface of the inner sheet.

Description

technical field [0001] The invention relates to a multi-layer flexible planar material for delimiting a matrix inlet cavity during the manufacture of a fiber-reinforced plastic component composed of a fiber composite semi-finished product by means of an injection method for injecting a matrix material, wherein the planar The material has an air-permeable but substrate-impermeable film, an air-impermeable foil and a highly air-permeable spacer layer which is placed between the film and the foil and which holds the foil in constant contact with the film when a low pressure is created between the film and the foil. distance. Background technique [0002] In the production of fiber-reinforced plastic components, it is known to first combine dry fiber-composited semi-finished products (so-called preforms), which have absorbed a flowable, hardenable matrix material (in the form of resin). The dry fiber composite semi-finished product can be a fabric, multi-dimensional layup or ch...
