Abstract: Provided is an impact-absorbing auxiliary material for a vehicle, which is fabricated using pulp containing a biodegradable plastic resin, so that a mold may be easily manufactured without regard to a shape of the auxiliary material, and in particular, which is environmentally friendly so that no waste treatment problems occur in discarding waste and an overall weight thereof is reduced. In particular, provided is an impact-absorbing auxiliary material for a vehicle, which is capable of obtaining sufficient impact-absorbing performance required in the impact-absorbing auxiliary material through successive deformation of ridges and ribs by connecting ribs between hollow ridge portions and forming integrally.

Abstract: Provided is an impact-absorbing auxiliary material for a vehicle, which is fabricated using pulp so that a mold may be easily fabricated without regard to a shape of the auxiliary material for absorbing the impact, and moreover, which is environmentally friendly and does not generate a waste treatment problem when being discarded. Also provided is an impact-absorbing auxiliary material of a vehicle, which is capable of obtaining a sufficient impact-absorbing performance required in the impact-absorbing auxiliary material through continuous deformation of ridges and ribs by connecting ribs between hollow ridge portions and forming integrally. The auxiliary material includes a base fabricated using pulp, wherein hollow ridges integrally protrude from the base in a plurality of rows at predetermined intervals, and the ridges adjacent to each other are connected to each other through ribs.
