Patent

CA 2624332

A thermally expandable material is provided that, once expanded, has a Young's storage modulus E' between 0.1 MPa and 1000 MPa, a loss factor of at least 0.3 (preferably, at least 1) and a shear storage modulus G' preferably between 0.1 MPa and 500 MPa at a temperature between -10 and +40 degrees C in the frequency range 0 to 500 Hz. Such materials are useful in connection with reducing the transfer of vibrations from a vibration generator, as may be present in a vehicle.

L'invention concerne un matériau thermiquement dilatable qui, une fois dilaté, présente un module de conservation de Young E' compris entre 0,1 MPa et 1000 MPa, un facteur de pertes d'au moins 0,3 (de préférence d'au moins 1) et, de préférence, un module cumulé de cisaillement G' compris entre 0,1 MPa et 500 MPa à une température située entre 10 et 40 °C dans la gamme de fréquence allant de 0 à 500 Hz. De tels matériaux sont utilisés en rapport avec la réduction du transfert des vibrations d'un générateur de vibrations, comme il peut en exister dans un véhicule.
