NOVELTY - The method involves supplying (9) polymethacrylimide (PMI) in the center of a foam core in a pultrusion process, where a cover layer is formed from a fiber material and a thermoplastic or thermosetting plastic by the pultrusion process. The foam core is guided continuously in a pultrusion system as multiple individual pieces. The fiber material is selected from carbon-, glass-, polymer fibers, particularly aramide fibers, or textile fibers, particularly aramide- or carbon fibers. The thermosetting plastic is formed of a polyester-, vinyl ester-, phenolic-, polyurethane- or epoxy resin.    USE - Method for the continuous production of fiber-reinforced endless profiles filled with a polymethacrylimide foam core, particularly a hollow profile used in automotive-, commercial vehicle-, ship-, aircraft-, helicopter construction, and in wind generation system and aerospace system (all claimed).    ADVANTAGE - The fiber-reinforced endless profiles are produced in a fast and cost effective manner with minimum modifications, where the profiles are produced continuously into individual workpieces with desired length. The workpieces are formed with improved mechanical properties and high compression strength. The elimination of the joining points in the profile ensures uniform maximum mechanical stress and increased stability of the profile, while the elimination of the adhesive layer ensures reduced weight and simple fabrication of the profile.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a polymethacrylimide foam filled hollow profile formed without the joining points and the adhesive layer.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a foam core filled profile production method.
