Tool, Arrangement, and Method for Manufacturing a Component, Component

Abstract

This application describes a tool, an arrangement, and a method of manufacturing a component. The manufacturing of the component is achieved by a resin transfer from a storage chamber via a transfer line into a working chamber. Before the resin transfer, taking place, for example by a compressed air charging of the storage chamber, the storage chamber is filled with an amount of resin adjusted to the size of the component. furthermore, a semi-finished product, consisting of cut-to-size reinforcement fibers, is inserted into the working chamber that is adjusted to the form of the component to be produced. Storage chamber, transfer line, and working chamber are configured in a one-piece mould casing of the tool. The application further describes a component manufactured by the above-mentioned tool or by the above-mentioned method respectively.

 the transfer line has a flow-through channel.   
     
     
         10 . The tool according to  claim 1 , wherein the storage chamber is configured such that
 the resin is pourable from a dosing device into the storage chamber.   
     
     
         11 . The tool according to  claim 1 , wherein the storage chamber is configured such that
 resin in the form of a granulate is pourable into the storage chamber.   
     
     
         12 . An arrangement for manufacturing a fiber-reinforced composite component by a resin-transfer-moulding process, comprising:
 a tool manufacturing the component comprising:
