A method for the integration of hollow space structures in fiber composite shells forming

摘要

The present invention relates to a method for the integration of the hollow space in the fiber composite structures forming bowls, comprising the steps of:a) production of an open cavity-forming profile (9),b) production of a gusset strip (1) as in the direction of the width of dimensionally stable pressure piece, wherein the width of the gusset strip (1) on the open cavity-forming profile (9) is adapted and the wedge belt (1) of a band-shaped wedge carrier (2), on which of the plane of the wedge carrier (2) in the form of wedge-shaped projections extending lips (3) are formed, whose outer surfaces (4) for the contacting of the inner sides (13) of the cavity-forming profile (9) during the positioning of the cavity-forming profile (9) on the wedge belt (1) are provided and the inner surfaces (5) for the adaptation of the film tube (11) are formed,c) of the structure of an uncured shells laminate (10),d) mounting and positioning of the gusset strip (1) on the uncured shells laminate (10),e) the application of a film tube (11) on the wedge belt (1),f) positioning of the open cavity-forming profile (9) on the wedge belt (1), wherein the width of the gusset strip (1) is coordinated in such a way that the wedge belt (1) at its outer edges (6) through the profile (9) is held,g) and conforming of the film tube (11) between the gusset strip (1) and the open cavity-forming profile (9),h) hardening of the integral shell - stringers - composite (8) of wedge belt (1), hollow space forming profile (9) and the shells laminate (10), wherein the individual elements (1, 9, 10) of the integral shell - stringers - composite (8) to be adhesively bonded to one another andi) demolding of the shell - stringers - composite (8) and removal of the film tube (11).
