    • A cavity filler insert for use in a cavity of a structural member is disclosed. According to one embodiment of the invention, the cavity filler insert is substantially planar in shape and includes a carrier, a thermally expandable material operably coupled with and supported by at least a portion of the carrier and extending at least around substantially the entire periphery of said cavity filler insert, and an attachment member for securing the cavity filler insert to the structural member. Once activated by heating so as to cause the expandable material to foam, the cavity filler insert effectively reduces both air-borne and structure-borne noise by dampening sound and vibration within hollow portions of vehicles and the like.
    • 公开了一种用于结构构件的空腔中的空腔填料插入件。 根据本发明的一个实施例,空腔填充插入件的形状基本上是平面的,并且包括载体,可热膨胀的材料,其可操作地与载体的至少一部分耦合并且由载体的至少一部分支撑,并至少围绕所述 空腔填料插入件和用于将空腔填料插入件固定到结构构件的附接构件。 一旦通过加热激活以使可膨胀材料发泡,则空腔填充插入物通过抑制车辆等的中空部分中的声音和振动来有效地减少空气传播和结构噪声。
