    • A method of forming a multilayer insulation material formed of an acoustical composite layer and a first thermal layer is provided. The acoustical and insulting layer is formed of a polymer based thermoplastic material and reinforcing fibers. Preferably the reinforcing fibers are wet use chopped strand glass fibers (WUCS). The acoustical composite layer may be formed by opening the WUCS fibers, blending the reinforcement and polymer fibers, forming the reinforcement and polymer fibers into a sheet, and then bonding the sheet. A first thermal layer formed of one or more polymer based thermoplastic organic materials is then positioned on a first major surface of the acoustical composite layer. A second thermal layer of polymeric fibers may be optionally positioned on a second major surface of the acoustical composite layer. The multilayer acoustic material may be utilized in semi-structural and acoustical applications.
    • 提供一种形成由声学复合层和第一热层形成的多层绝缘材料的方法。 声学和绝缘层由聚合物基热塑性材料和增强纤维形成。 优选地,增强纤维是湿式使用短切玻璃纤维(WUCS)。 声学复合层可以通过打开WUCS纤维,混合增强材料和聚合物纤维,将增强材料和聚合物纤维形成片材,然后粘合片材而形成。 然后将由一种或多种基于聚合物的热塑性有机材料形成的第一热层定位在声学复合层的第一主表面上。 聚合物纤维的第二热层可以任选地定位在声学复合层的第二主表面上。 多层声学材料可用于半结构和声学应用中。
