A method for producing a fiber composite component includes a step (a) that includes a production of a semi-finished product by: providing a core layer having cavities; covering an outer face of the core layer with a layer-shaped semi-finished product having continuous fibers pre-impregnated with a first duroplastic matrix material; and applying a molding compound to a first deposit area of a front face of the first semi-finished product, the front face facing away from the core layer, wherein the molding compound includes a second long-fiber-reinforced duroplastic matrix material. The method also includes a step (b) for extruded reshaping of the semi-finished product to the fiber composite component. The extruded reshaping is performed at an operating temperature, and the first and the second matrix material are configured such that flowability of the second matrix material is higher than flowability of the first matrix material during the reshaping.

A method is provided for connecting hollow profiles (1-4) in a joint (10) to produce a load-bearing structure (5). The method includes placing ends of hollow profiles (1-4) in a mold and pressing the ends together with at least one semi-finished product to connect the ends of the hollow profiles to the semi-finished product.

A suspension arm includes: a vibration-proof bush including tubular fittings, a tubular elastic member formed on an outer periphery of the tubular fittings, and a resin band that is wound around an outer peripheral surface of the tubular elastic member and imparts a pre-compression in a radial direction of the tubular elastic member; and a resin arm fixed to the vibration-proof bush by integrally forming a resin material so as to surround the outer periphery of the vibration-proof bush.
