A linear wall or ceiling panel comprising and formed from a woven or non-woven fibrous material. Preferably, the material is thermoformable and non-woven and comprises at least one of the group consisting of: bi-core polyester fibers: two different types of fibers having different melting points; a mixture of bi-core polyester fibers and non-bi-core (single core) polyester fibers. The panel is preferably shaped to provide means for mounting the panel to a carrier. Optionally, an end portion may be provided to cover the open longitudinal end of the linear panel.

A component part for a motor vehicle having a hollow profile portion of a fiber-reinforced plastic and a load introduction element of a metal material. The hollow profile portion and the load introduction element are connected in a common connection portion via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion engage in one another by positive engagement. The end portion of the load introduction element has a spline with teeth extending in longitudinal direction of the common connection portion so that the stiffness of the end portion of the load introduction element reduced in longitudinal direction of the common connection portion.

A method for connecting a surface-structured workpiece (SSW) and a plastic workpiece using a joining tool with a sonotrode. The method includes: positioning the SSW and the plastic workpiece on an anvil such that a structured contact surface section (SCSS) of the SSW faces a contact surface of the plastic workpiece; positioning the sonotrode in contact with an outer surface of the SSW that is opposite to the SCSS; and applying pressure to the sonotrode and/or the anvil perpendicular to the contact surface to hold the workpieces fixed between the anvil and the sonotrode and applying ultrasonic vibrations to the workpieces by the sonotrode for a predetermined period of time to induce softening of the plastic workpiece and penetrate pin-like elements of the SCSS into the plastic workpiece.

A method for joining sections of at least two components, particularly vehicle components, includes mutually connecting the joining sections exclusively by the use of a fibrous duroplastic molding compound.
