WINDING METHOD FOR THE PRODUCTION OF A ROTATIONALLY SYMMETRIC, TUBE-LIKE HOLLOW BODY PREFORM, DEVICE AND METHOD FOR THE PRODUCTION OF A DEVICE FOR PRODUCING THE SAME

摘要

Winding method for the production of a rotationally symmetric, tube-like hollow body preform, device (10) for the production of a rotationally symmetric, tube-like hollow body preform and a method for the production of a device for producing a rotationally symmetric, tube-like hollow body preform, wherein reinforcing fibres soaked with a resin are wound in a winding process on a rotatably driven winding core (1) having an outside diameter corresponding to the inside diameter of the hollow body preform and wherein the hollow body preform is removed from the winding core after a subsequent hardening of the hollow body preform by means of supplied heat. For the winding process and/or hardening of the hollow body preform, the outside diameter of the winding core corresponds to the inside diameter of the hollow body preform to be produced, wherein the outside diameter of the winding core is reduced to a smaller outside diameter for the removal of the hollow body preform from the winding core.

1. A winding method for producing a rotationally symmetrical tube-like hollow-body preform, wherein reinforcing fibers impregnated with a resin are wound, in a winding operation, onto a rotatably driven winding core of which an outer diameter corresponds to an inner diameter of the hollow-body preform and wherein, after subsequent curing of the hollow-body preform by means of supplied heat, the hollow-body preform is removed from the winding core, characterized in that, for at least one of the winding operation and the curing of the hollow-body preform, the outer diameter of the winding core (1, 1′) has the outer diameter which corresponds to the inner diameter of the hollow-body preform to be produced and wherein, for removing the hollow-body preform from the winding core (1, 1′), the outer diameter is reduced to a smaller outer diameter.
