A porous structural unit and a method of preparing the same. |
摘要 |
The present invention concerns a method of preparing a porous structural unit comprising a plurality of layers having different specific gravities by pressing and heating a material including resin particles between opposing molds (7,8) having a temperature difference to thereby cause the fusion or bonding of the resin particles, and a porous structural unit which improves acoustic absorption properties and heat insulation properties and in which the specific gravity is continuously changed. |
