Abstract
A draping and molding tool to manufacture a preform is consolidated at least in sections and includes two tool halves, the surfaces of which are arranged facing one another. At least one of the tool halves includes a plurality of ram segments, which have a lifting movement, and are individually controllable and are individually moveable. The ram segments form a tool surface of the tool half.

A draping and molding tool for manufacturing a preform, comprising:
- two tool halves, the surfaces of which are facing one another, which is consolidated at least in sections,
- wherein at least one of the tool halves comprises a plurality of ram segments, which are configured to have a lifting movement and which are individually controllable and individually moveable, said ram segments forming a tool surface of the tool half and having different widths, depths, or are actuated hydraulically, pneumatically or electromotively.
A method to create a preform, which is molded and consolidated at least in sections, using a draping and molding tool comprising two tool halves, the surfaces of which are facing one another, which is consolidated at least in sections, the method comprising:
- arranging fiber layers comprising a binder material between the tool halves in the draping and molding tool, of the two tool halves, at least one tool half of whose two tool halves comprises ram segments, which have a lifting movement, are individually controllable and are individually moveable;
- and
- controlling the ram segments and local successive movement of the ram segments in a direction of the inserted fiber layers and therein draping of the fiber layers as a stack by means of local pressure.
A method to produce a fiber plastic composite component from a preform using a draping and molding tool comprising two tool halves, the surfaces of which are facing one another, which is consolidated at least in sections, the method comprising:
- manufacturing a preform by
- arranging fiber layers comprising a binder material between the tool halves in the draping and molding tool, of the two tool halves, at least one tool half of whose two tool halves comprises ram segments, which have a lifting movement, are individually controllable and are individually moveable;
- and
- controlling the ram segments and local successive movement of the ram segments in a direction of the inserted fiber layers and therein draping of the fiber layers as a stack by means of local pressure
- injecting a matrix-forming plastic system and impregnating of the preform, left in the closed draping and molding tool, with the matrix-forming plastic system;
- preparing setting conditions for the matrix-forming plastic system by heating of the impregnated preform to a setting temperature of the matrix-forming plastic system and by exerting a compression pressure through the ram segments of the at least one tool half;
- and
- setting and demolding the fiber plastic composite component.
