First Claim
1. Ready-made technical process for manufacturing fiber-reinforced plastic building components comprised of a link and at least one flange that extends in the longitudinal direction using textile blanks (10) as starting material including the steps of:
- the positioning vis-à
-vis one another, clamping in and initial sewing-up of at least two layers of textile blanks in order to fix the former into place relative to one another for the purpose of realizing a preform, infiltrating the preform with resin for the purpose of manufacturing the plastic building component, wherein, following the initial sewing-up of the textile preforms, an end area (1a) of the at least two layers that extend in the longitudinal direction is turned up (step 30) by a predetermined angle in order to create the flange, the turned up edge area is applied (step 40) to a linearly extending contact surface (42) of a form element (41), the link area (2) is fixed in place relative to the turned up edge area in a sewing material holder (52) and the layers are sewed up in at least one of the sewing windows (87) envisioned in the sewing material holder (52).
