Preparation of composite fibre semi for spatial deformation, comprises local deep-drawing or draping

摘要

The deformation takes place through local deep-drawing, draping or in event of a crash. The structure and/or fibres of the semi (10) are altered through needling (35) in an area of an e.g. a car to be deformed. The sections to be needled is needled less strongly in a subsection (40) on the edge than in a central subsection (50).
