  • Baffle with enhanced acoustic damping properties
    Patent number: 8469143
    Abstract: An insert for sealing and acoustic damping of a longitudinal cavity having an interior surface, comprising: a) one or more carrier plates made of a polymeric material (A) which does not deform when heated to a temperature not higher than 180° C. and which comprises a main polymer (A1) which gives mechanical strength to the carrier plate, and—at least one vibration-damping polymer (A2), and b) a thermally expandable material (B). The vibration-damping polymer (A2) is preferably selected from the group comprising: thermoplastic polyurethanes, styrene/butadiene block copolymers, hydrogenated styrene/butadiene block copolymers, styrene/isoprene block copolymers, hydrogenated styrene/isoprene block copolymers, styrene/isoprene/styrene tri-block copolymers, and hydrogenated styrene/isoprene/styrene tri-block copolymers.
    Type: Grant

    Inventors: Fabrice Prunarety, Jean-Luc Wojtowicki, Josef Hudina
  • Acoustic baffle
    Patent number: 8215704
    Abstract: A heat expandable baffle having a shape corresponding to, but smaller than, the shape of the cross section of a cavity to be sealed, and comprising a rigid support plate, a carrier for a heat expandable material and a heat expandable material mounted only to the outer periphery of the carrier. When activated by heating, the expandable material expand radially from the carrier to seal the cross sectional gap between the carrier and the cavity wall.
