The invention relates to a vehicle component having at least one sandwich part which forms a crash element that absorbs kinetic energy. The at least one sandwich part (1; 1'; 101) has a layer structure (10; 10'; 10) of at least two fiber-reinforced and one synthetic resin matrix-containing cover layer elements (12, 16; 13, 17; 112, 116) and at least one core layer element (14; 15; 114) provided between two adjacent cover layer elements (12, 6; 13, 17; 112, 116). The at least one core layer element (14; 15; 114) has channels (2; 2'; 121) which pass transversely through each cover layer element (12, 16; 3, 17; 112, 116) and/or the core layer element (14; 15; 114). The invention is characterized in that the at least one core layer element (14; 15; 114) is made of a hard foam material or a softwood, and the channels (2; 2'; 121) provided in the core layer element (14; 15; 114) form predetermined breaking points for the core layer element (14; 15; 114). |
