Method and a device for the preparation of a dry textile preform

摘要

A method for the preparation of a dry textile preform for a large surface area fiber-reinforced composite component, in which resin-free textile material layers for purposes of manufacturing the preform are tensioned in each case in a tensioning frame, and in the stretched state are laid down on a moulding body by means of a linear relative movement between the tensioning frame and the moulding body. Also disclosed is a device for the execution of a method of this type with a tensioning frame for purposes of tensioning the material layers, and with a clamping unit for purposes of fixing the laid-down material layers on a moulding body.

1. A device for the preparation of a dry textile preform for a large surface area component comprising:
a moulding body with a mould surface for purposes of accommodating at least one dry fibre entity, a tensioning frame for purposes of laying down the at least one fibre entity on the mould surface, wherein the tensioning frame is adapted for tensioning the at least one fibre entity with a defined tensile force at a distance from the moulding body, for positioning the at least one fibre entity relative to the moulding body and for laying down the fibre entity on the moulding body and a clamping unit for purposes of fixing the at least one fibre entity on the moulding body, wherein a multiplicity of suction ports are designed in the mould surface for purposes of connecting to a vacuum unit, as are recesses for purposes of accommodating at least one resin connecting pipe and at least one vacuum connecting pipe.
