Abstract
A reinforcing and vibration-damping material has a laminate body which includes a constraining layer acting to reinforce an adherend to which the material is to be applied, a vibration-damping layer acting to damp vibrations in the adherend and a binder layer interposed between the constraining layer and the vibration-damping layer. Further, a hardenable pressure sensitive adhesive layer is formed on the vibration-damping layer of the laminate body, and a release liner is placed around the hardenable pressure sensitive adhesive layer. The constraining layer exhibits the advantageous effect of reinforcing the adherend, and comprises, for example, a hard material such as a metal. The binder layer comprises a pressure sensitive adhesive, a bonding agent or a hardenable pressure sensitive adhesive. The vibration-reinforcing layer comprises a viscoelastic material containing unvulcanized rubber and a vulcanizing agent for example. The hardenable pressure sensitive adhesive layer comprises a hardenable pressure sensitive adhesive which is tacky in the uncured state but has a strong adhesive force when it is cured by heating, irradiation or being blocked from air. Thus constructed, the re…
