Abstract

A ready-made technical process for manufacturing fiber-reinforced plastic building components envisions the use of a link and, optionally, a flange and/or a base using textile blanks as starting material. Initially, at least two layers of the textile blanks are positioned vis-á-vis one another, clamped in and undergo a first sewing-up process. A preform is fashioned featuring the architecture of the product that is to be manufactured, and subsequently the preform is infiltrated with resin in order to realize the plastic building component. A tension module realizes a flange on a textile preform and a sewing material holder receives a textile preform in order to implement the steps referred to.

Claims

1. A process for manufacturing a fiber-reinforced plastic building component comprised of a link and at least one base that extends linearly in a longitudinal direction using textile blanks as starting material comprising:

positioning, clamping in, and initially sewing-up at least two layers of textile blanks in order to fix the layers into place relative to one another and realize a preform, and

infiltrating the preform with resin in order to manufacture the plastic building component,

wherein, following initially sewing-up the at least two layers of textile blanks, a contour seam is inserted along an end area of the preform, the end area is turned up at a predetermined angle in order to realize a course of the at least one base that is to be created, a gusset extending in a longitudinal direction of the contour seam is inserted between the at least two layers, and the at least two layers are sewed up in at least one sewing window in a sewing material holder, and

wherein the end area is fixed in place by way of stiffening elements.

2. The process as claimed in claim 1 wherein a fastening seam is inserted in the at least two layers in order to fix the gusset in place.

3. The process as claimed in claim 1 wherein the gusset is pressed against the contour seam by way of a pressing element.

4. The process as claimed in claim 2 wherein the gusset is pressed against the contour seam by way of a pressing element.

5. The process as claimed in claim 1 wherein a flange is realized on another end area by clamping in and turning up the other end area extending in the longitudinal direction of the at least two layers by a predetermined angle, the turned up edge area is applied against a linearly extending contact area of a form element, and the link is fixed in place relative to the turned up edge area inside the sewing material holder.

6. The process as claimed in claim 2 wherein a flange is realized on another end area by clamping in and turning up the other end area extending in the longitudinal direction of the at least two layers by a predetermined angle, the turned up edge area is applied against a linearly extending contact area of a form element, and the link is fixed in place relative to the turned up edge area inside the sewing material holder.

7. The process as claimed in claim 3 wherein a flange is realized on another end area by clamping in and turning up the other end area extending in the longitudinal direction of the at least two layers by a predetermined angle, the turned up edge area is applied against a linearly extending contact area of a form element, and the link is fixed in place relative to the turned up edge area inside the sewing material holder.
