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.
