    • A member having a cavity comprising an insert for sealing and acoustic damping, comprising at least two carrier plates intersecting along a line parallel to the cavity axis, and this insert as such. Each carrier plate has two plate surfaces, a longitudinal edge running essentially parallel to the longitudinal cavity axis, and a front and a rear edge running essentially perpendicular to the longitudinal cavity axis, placed in the longitudinal cavity in a way that the perpendicular plate axes of the carrier plates are perpendicular to the longitudinal cavity axis. The inserted insert divides the longitudinal cavity in at least three subsections which are parallel to the longitudinal cavity axis. The carrier plates are covered on one or more plate surface(s) with a layer of a thermally expandable material in a way that after expansion of the material all the subsections of the cavities are completely filled with the expanded material, whereby the thermally expandable material expands by at least 1000 % when heated at a temperature in the range of from 130 to 220 0 C. Methods to make these inserts and methods to seal cavities using these inserts are also claimed.
    • 具有腔体的构件包括用于密封和声学阻尼的插入件,包括沿着与腔体轴线平行的线相交的至少两个承载板,并且该插入件本身。 每个承载板具有两个板表面,基本上平行于纵向腔轴线的纵向边缘,以及基本上垂直于纵向腔体轴线延伸的前边缘和后边缘,该纵向边缘以纵向腔体的垂直板轴线 承载板垂直于纵向腔轴线。 插入的插入物在至少三个与纵向腔轴线平行的子部分中分割纵向空腔。 载体板在一个或多个具有可热膨胀材料的层的一个或多个板表面上以这样的方式被覆盖,即在材料膨胀之后,所有空腔的所有部分都被膨胀材料完全填充,由此可热膨胀的材料 在130〜220℃的温度范围内加热至少1000%。 还要求保护这些插入物的方法和使用这些插入物来密封空腔的方法。
