Abstract: A lightweight construction element (2) for a body of a motor vehicle (1) with a support frame (3) having four frame parts (5, 6, 7, 8), which essentially spans a square and with panelling (4) mounted on the support frame (3). The the support frame (3) is made of a fiber-reinforced plastic and has at least two intersecting braces (9, 10, 11, 12, 13, 14, 16, 17, 19, 20) that are designed according to bionic aspects and in which the intersection or intersections (15, 18) are connected and each of which join two of the frame parts (5, 6, 7, 8) perpendicular to one another with one another.

Abstract: A component (1) for the outer surface of a vehicle (F), with a fibre composite (2) and at least one matrix plastic serving to stabilise the fibre composite (2). Optically or optically-electrically active elements (3) are integrated into the fibre composite (2). The optically active elements (3) have electroluminescent fibres (3) and/or the fibre composite (2) has an at least partial electroluminescent coating (7) as the optically active elements (3), which is in contact with electrically conductive fibres in the fibre composite (2).
