  • Publication number: 20260139544
    Abstract: The invention relates to a method for producing a corner connection (1) between two mitre-cut hollow-chamber profile portions (14, 14?) using a connecting element (2) which has two legs (3, 3?) arranged in an angled manner, depressions (4, 4?) on the outer side of the legs (3, 3?), and a channel system (10) in the legs for guiding a thermoplastic connecting compound, which channel system (10) has inflow openings (7, 7?) and also outlet openings (11, 11?) which open into the depressions (4, 4?), the method comprising: (a) providing the portions (14, 14?); (b) incorporating through-openings through the walls of the hollow-chamber profile in such a way that the through-openings and the inflow openings (7, 7?) of the channel system (10) are aligned when the legs (3, 3?) have been introduced into a respective hollow chamber (13, 13?) of the portions (14, 14?); (c) introducing the legs (3, 3?) into a respective hollow chamber (13, 13?) in such a way that the through-openings and the inflow openings (7, 7?) are alig

  • Patent number: 12420499
    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.

  • Publication number: 20250207454
    Abstract: The present invention relates to a window or door hollow chamber profile (1), comprising (a) a core profile comprising a plastic matrix formed of a thermoplastic polyamide material and reinforcing fibres contained in the plastic matrix; and (b) a sheath profile (40) at least partially sheathing the core profile (30) and made of a thermoplastic material compatible with the plastic material of the core profile (30), wherein the window or door hollow chamber profile (1) is distinguished in accordance with the invention in that the thermoplastic material of the sheath profile (40) compatible with the plastic material of the core profile (30) is a blend of a polyamide material and an acrylonitrile-styrene-acrylic ester terpolymer (ASA). The present invention additionally relates to a window or door frame which is formed from portions of a window or door hollow chamber profile (1) according to the invention.

  • Publication number: 20250207456
    Abstract: The present invention relates to a window or door hollow chamber profile (1), comprising (a) a core profile (30) comprising a plastic matrix formed of thermoplastic material and reinforcing fibres contained in the plastic matrix; and (b) a sheath profile (40) at least partially sheathing the core profile (30) and made of a thermoplastic material compatible with the plastic material of the core profile (30), wherein the window or door hollow chamber profile (1) is distinguished in accordance with the invention in that the thermoplastic material of the core profile (30) is a polyamide material and the reinforcing fibres are short fibres with an average fibre length in the range from 0.1 mm to 12 mm. In addition, the present invention also relates to a corner connection that has been obtained by welding at least partially mitred portions of a window or door hollow chamber profile (1) of this kind.
