加强的热塑性物品、用于制造该物品的组合物、制造方法和由其形成的物品
摘要：
一种用于制造多孔、可压缩的物品的组合物，该组合物包括：多个加强纤维、多个聚砜纤维和多个聚合粘合剂纤维的组合，其中，聚合粘合剂纤维具有比聚砜纤维低的熔点；用于形成多孔、可压缩的物品的方法；和含有多孔、可压缩的物品的物品。也公开了包括热成型的双基质复合材料的物品，其中，复合材料表现出如通过FAR 25.853(OSU检验)测量的到达峰值释放的时间，如通过FAR 25.853(OUS检验)测量的，2分钟总热释放，和根据ASTM E-662(FAR/JAR 25.853)确定的，在4分钟小于200的NBS光学烟雾密度。
摘要（英）：

Provided is a composition for the manufacture of a porous, compressible article, the composition comprising a combination of: a plurality of reinforcing fibers; a plurality of polysulfone fibers; and a plurality of polymeric binder fibers; wherein the polymeric binder fibers have a melting point lower than the polysulfone fibers; methods for forming the porous, compressible article; and articles containing the porous, compressible article. An article comprising a thermoformed dual matrix composite is also disclosed, wherein the composite exhibits a time to peak release, as measured by FAR 25.853 (OSU test), a 2 minute total heat release, as measured by FAR 25.853 (OSU test), and an NBS optical smoke density of less than 200 at 4 minutes, determined in accordance with ASTM E-662 (FAR/JAR 25.853).
