Abstract: A method for providing spacers on a construction component to be adhered involves applying a planar formation, including passages, on the construction component to be adhered, and inserting a setting liquid in the passages of the planar formation, so that the liquid forms spacer on the construction component to be adhered after setting and peeling off the planar formation. The spacer ensures a predetermined minimum bondline when adhering the construction component.

Abstract: A resin infusion apparatus and system, layup system comprising the same, and methods of using these are provided. The resin infusion apparatus comprises a hollow cylinder having a plurality of pores perforating an arcuate surface thereof.

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-à-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.
