  • Laminated vibration-damping material
    Patent number: 5368916
    Abstract: A laminated damping material comprises a layer of a thermosetting resin having vibration-damping properties as a core layer and two heat resistant films adhesive to the core layer, the core layer being sandwiched between these two heat resistant films. The damping material can be used for preparing a fiber-reinforced composite material which comprises at least one basic layer structure, outer layer/intermediate layer/core layer/intermediate layer/outer layer, the intermediate layer being formed from a heat resistant film having good adhesive properties to both outer and core layers and the core layer being formed from a thermosetting resin. The fiber-reinforced composite material exhibits high vibration-damping properties and accordingly can suitably be used, as a structural material, for the production of not only cars and equipments for leisure time amusement but also space structures such as artificial satellites and air planes.

  • Thermal adhesive vibration damping sheets
    Patent number: 5227234
    Abstract: A thermal adhesive vibration damping sheet comprising a sheet substrate having crystalline polyolefin particles attached to a surface thereof, said polyolefin particles having a mean particle size of 1 to 20 .mu.m and exhibiting an endothermic curve having a high temperature side endothermic peak in the range of from 50.degree. to 230.degree. C. as measured by a differential scanning calorimeter. The sheet has improved blocking resistance, adhesion to sheet steel through heat fusion, and impact resistance at low temperatures.
