Body shell support e.g. crash-box, for use in body shell structure of sports vehicle, has hollow space filled with biopolymer or mixture of different biopolymers for reinforcement or stiffening and damping vibration of structure

摘要

The support (1) has a hollow space (2) filled with a biopolymer (5) or a mixture of different biopolymers in an area-wise for reinforcement or stiffening of a body shell structure and for damping vibration of the body shell structure, where the support is designed in a hollow type. A lignin, protein, peptide, nucleic acid, polysaccharide, lipid and lignin are utilized as the biopolymer, and the hollow space is enclosed by a wall (3). A separation line (4) is divided into right and left halves, and the biopolymer is formed as a lining for the wall.
