Motor car monocoque i.e. carrying body structure component, has overhead panel and lower shell interconnected and processed through injection molding of thermoplastic plastic, where lower shell is constantly closed

摘要

The monocoque (10) has an overhead panel (11) and a lower shell (12) interconnected and processed through injection molding of thermoplastic plastic. The lower shell made from glass-fiber reinforced thermoplastic plastic and the overhead panel made from glass-fiber reinforced thermoplastic plastic are connected at edges and/or flanges (13, 14) for forming a cavity (15) in the shell. The overhead panel and the lower shell are connected by adhering and friction welding. The lower shell is constantly closed and opening-freely formed, and the overhead panel comprises apertures.
