Manufacturing method for composite structure, particularly multilevel composite structure, involves applying fiber layer on support structure and inserting filing unit in cavity of structure and injecting matrix material into fiber layer

摘要

The method involves applying a fiber layer on a support structure (2). A filing unit is inserted in an cavity (4) of the support structure. The matrix material is injected into the fiber layer and the fiber-reinforced layer (5) is hardened. The fillling unit is removed from the cavity. The filling unit in the support structure is removed through openings (3). An independent claim is also included for the composite structure particularly multilevel composite structure.
