Abstract:
1. A method of producing a fibre reinforced structural element including a plurality of fixating elements for the fixation of said structural element to another structural element, the method comprising the steps of: i) providing a fixating element selected from the group consisting of bolt fixtures, bolts, fittings, and any combination thereof; ii) providing an elongated core element of a material compatible with the materials of said fibre reinforced structural element, said core element having an end part with a specific configuration; iii) mounting said fixating element on said end part of said core element to produce a subassembly; iv) fixating said fixating element relative to said end part of said core element in a pultrusion process selected from the group consisting of (a) pulling said subassembly through a pultruder, circumferentially covering said subassembly with reinforcing fibres and resin, and heating and curing said resin for causing said resin to provide, in conjunction with said reinforcing fibres, a casing circumferentially encircling said subassembly, and (b) encasing said subassembly by adhesion in a casing of fibre-reinforced resin produced in a separate pultrusion process; v) machining said subassembly within said casing of said reinforcing fibres and said cured resin to produce a fixating element assembly including said core element and said fixating element; vi) repeating said steps i)-v) to produce a plurality of fixating element assemblies; vii) positioning said plurality of assemblies according to intended positions of said fixating elements within said fibre reinforced structural element; and viii) producing said fibre reinforced structural element including said fixating elements and said plurality of assemblies in a production technique selected from the group consisting of at least one of extrusion, pultrusion, or a fibre reinforcing production technique.
