METHOD AND APPARATUS FOR MANUFACTURING A SANDWICH PART AND SANDWICH PART

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for manufacturing a sandwich component with a class-A surface and a sandwich component.SOLUTION: The method for manufacturing a sandwich component, comprises: a step (S1) of lining or encapsulating a honeycomb core (1) having a plurality of webs on both sides with at least one ply (2) of a fibrous material, the plies (2) forming cover plies; a step (S2) of impregnating, wetting, or spraying a pack composed of the honeycomb core (1) and fibrous plies (2) with a matrix (3); a step (S3) of compressing and hardening the pack in a compression molding tool (4) to form a component in accordance with the required component geometry; and a step (S7) of applying a class-A surface at least on a visible side of the component as an RIM layer (5) in a Reaction Injection Molding (RIM) process, in particular in a Vacuum Reaction Injection Molding (V-RIM) process. An apparatus and a sandwich component are also provided.SELECTED DRAWING: Figure 1
