Abstract
The invention relates to a method for producing a fiber-reinforced, polymeric continuous profiled element (1), wherein the continuous profiled element (1), having preferably at least one hollow chamber (2, 2′), comprises a core profile (10) which can be produced by means of a pultrusion process, and wherein during the pultrusion process at least one continuous strand having reinforcement fibers (5) is integrated into the polymer matrix (4) of the core profile (10). According to the invention, the curing of the core profile (10) is carried out by means of a dual-cure method.
Claims11
A method for producing a fiber-reinforced polymeric continuous profile,
- wherein the continuous profile comprises a core profile which is produced with the aid of a pultrusion process,
- wherein at least one continuous strand having reinforcing fibers is integrated into the polymeric matrix of the core profile during the pultrusion process,
- wherein the core profile is provided with an extruded outer, thermoplastic coating immediately after being shaped,
- wherein the hardening of the core profile takes place using a dual cure method,
- wherein a second curing process of the dual cure method is a heat cure, and
- wherein an input of heat for the heat cure is via the application of a hot extrusion melt of the coating to the core profile.
