Embodiment Construction

[0033] figure 1 Shown is an internal fluid line 2 for the molding die (for example, a resin line for guiding resin) and a joint adapter 4 plugged on the fluid line. The coupling adapter has two support legs 6 and 8 which are designed essentially as planar elements and are arranged flush on the surface 10 of the inner fluid line 2 . Thus, the joint adapter can make a good flush contact with the internal fluid conduit 2 .

[0034]In particular, the material of the joining adapter 4 should have sufficient heat resistance and be as dimensionally elastic as possible. It is proposed to use castable elastic materials, preferably rubber elastic materials, which can withstand temperatures in excess of 180°C. It may be proposed to use castable high temperature rubbers, for example of the room temperature crosslinking type. Such materials are available for use at temperatures well above 200°C. Furthermore, the fluid connection between the internal fluid line 2 and the coupling adapte...

Abstract

A connection adapter for conducting resin into an inner fluid line of a device for vacuum infusion has a bearing side and a connection side, wherein the bearing side has two bearing legs for placing on a fluid line which form an interspace which widens outwardly in a direction facing away from the connection side, and wherein the connection side has a hollow-cylindrical portion with a connection opening facing away from the bearing side, and with a connecting opening projecting into the bearing side, and with a fluid connection between the connection opening and the connecting opening. The disclosure also relates to a system in which parts are made of fibrous composite materials.

Description

technical field [0001] The invention relates to a junction adapter for connecting internal fluid lines of a device for vacuum infusion, and a system for carrying out a vacuum infusion method. Background technique [0002] Different methods are known for producing components from fiber-reinforced plastics. The selection of a suitable method is usually based on the application and the planned number of parts to be produced. Large workpiece quantities and large component sizes are usually handled by the vacuum infusion method, in which the fiber semi-finished product is introduced into the mold, covered with an airtight film, and resin is then applied by applying negative pressure from a resin line located below the film. In order to supply sufficient resin flow to the internal resin line, it is essential to create a connection between the internal resin line and the external resin line. Since the internal resin lines are usually positioned directly at or in the fiber blank, ...
