PURPOSE:To perform fixation to a vibration base material of a constrained material and a damping material simply and surely by forming this constrained material with a constituent made up of mixing ethylenic resin and glass fiber in tackifier resin respectively at a specified wt. part rate. CONSTITUTION:A constrained material is laminated on a vibration base material for a vehicle or the like via a damping material. In this case, this constrained material is formed with a constituent made up of mixing at least an ethylenic resin 3-100wt. part and a glass fiber 3-75wt. part in a tackifier resin 200wt. part. This constrained material can be tightly fixed by heating the vibration base material and the damping material at the same time and, what is more, the number of manhour is reducible. In addition, there is not secular change in hardening capacity, and durability is improved, while such problems of fusion failure to the damping material and follow-up failure to the vibration base material are all solvable. |
