资源简介：
A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least (0.5) as tested by ASTM C423-17 and a flame spread index of less than (25) and a smoke development index of less than (150) as tested by ASTM E84 dated 2009.
本文描述了一种热塑性复合材料制品(thermoplastic composite article)，其包含多孔芯层(porous core layer)以及设置于该芯层第一表面的开孔表皮(open cell skin)。该复合材料制品经ASTM C423-17标准测试的降噪系数(Noise Reduction Coefficient)不低于0.5，且经2009版ASTM E84标准测试的火焰传播指数小于25、发烟指数小于150。
