TECHNOLOGY FOCUS - POLYMERS - Preferred Composite: In the composite profile, the foam core (1) comprises a polyurethane foam, an epoxy resin foam, a polyester resin foam, an expanded polystyrene foam and/or an expanded polypropylene foam. The foam core (1) comprises a polyurethane foam obtainable by the reaction of a mixture comprising: Component A: a polyol formulation, comprising: (a) one or more polyether polyols and or one or more polyester polyols and/or polyamines with hydroxyl numbers of 12 and 1200 mg KOH/g, and molecular weights of 60 and 7000 g/mol, and functionality from between 2 and 8; (b) none, one or more cross linkers and/or chain extenders with hydroxyl numbers of 500 and 2000 mg KOH/g, and molecular weights of 60 and 400 g/mol, and functionality from between 2 and 8; (c) one or more amine and/or organometallic and/or metallic catalysts; (d) none, one or more flame retardants which may be halogenated; (e) one or more surfactants; (f) one or more chemical and/or physical blowing agents; and Component B: an isocyanate, comprising: (a) diphenylmethane diisocyanate and/or polymeric diphenylmethane diisocyanate with a preferred monomer content from between 40-100 wt.% and with an isocyanate group (NCO)-content of 25-35 wt.%. The reinforcement fabric (4) comprises glass fibers, carbon fibers and/or aramid fibers. The foam core (1) is bonded to the reinforcement fabric (4) without the use of an additional adhesive. The profile comprises a set of foam cores (1) in contact with the reinforcement fabric (4). The reinforcement fabric (4) is a paper fabric and an additional reinforcement fabric (11) is at least partially in contact with the reinforcement fabric (4). Preferred Method: In manufacturing the composite profile, the reinforcement fabric (4) is a woven textile or an at least bidirectionally oriented non-woven textile. In step (a) the reinforcement fabric (4) is provided in such a shape as to define a set of upwardly open cavities (1') adapted to receive respective foams and in step (b) foam is provided into each cavity (1'). Step (b) comprises introducing a frothing and/or thixotropic foam (1) into the at least one cavity (1') of the reinforcement fabric (4). The foam (1) is a spreadable foam obtained from a reaction mixture and is provided into the at least one cavity (1') of the reinforcement fabric (4) after the cream time of the reaction mixture. The foam (1) comprises a polyurethane foam, an epoxy resin foam, a polyester resin foam, an expanded polystyrene foam and/or an expanded polypropylene foam. The foam (1) is bonded to the reinforcement fabric (4) without the use of an additional adhesive. The reinforcement fabric (4) is in a one-part form. Moreover, at least one section of the reinforcement fabric (4) is not part of the cavity (1') and the section is at least partially contacted by a removable masking unit (14, 14').
