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. The auxiliary material includes a base fabricated using pulp containing biodegradable plastic, wherein hollow ridges integrally protrude from the base in a plurality of rows at predetermined intervals, the ridges adjacent to each other are connected to each other through ribs, and the pulp and the biodegradable plastic are mixed in a weight ratio of about 50:1 to 70:1.
