PURPOSE:To improve the strength of a material, by constituting the compound vibro-isolating material filling at least an air hole of a communicative porous metal with elastomer. CONSTITUTION:A compound vibro-isolating material is constituted by filling an air hole 2 of a communicative porous metal 1 with elastomer such as polyurethane rubber or the like. Then the porous metal serves as a reinforcing member in respect of rigidity, further the elastomer, with which the air hole 2 is filled, is successively arranged over the whole unit because the air hole 2 is communicated. In this way, strength of the material can be improved without causing the elastomer to suppress its own absorptive power of low frequency vibration. |
