    摘要:

    回顾了国内外复合材料热特性相关领域的研究,梳理了这些研究的相似点和不同点,并指出了研究方向存在的空缺和不足,尤其是在适航层面研究的部分缺失。试验件为复材壁板和隔音棉相关衍生结构,并根据CCAR-25-R4和GB/T10671-2008固体材料产烟的比光密度试验方法,系统测试了复合材料、隔热隔音棉及其组合衍生构型的发烟特性,分析了隔热隔音棉对发烟特性的影响,探讨了现有适航条款及符合性验证方法的适用性。结果表明:复合材料机身壁板和隔热隔音棉衍生构型能够满足当前适航条款验证方法提出的符合性判据,隔热隔音棉有效降低了复材壁板的烟比光密度和烟气释放速率。

    Abstract:

    This article reviews recent studies of scholars in the field of thermal properties of composites at home and abroad, sorts out the similarities and differences of these studies, points out the vacancies and deficiencies in the research area, especially in the airworthiness level. Taking the composite material fuselage wall plate and thermal acoustic insulation blanket derived configuration as the research object, the smoke performance of composite materials, thermal acoustic insulation blanket and their derived configuration were systematically tested according to the CCAR-25-R4 and GB/T10671-2008 airworthiness standard. The effect of the performance was compared and analysed, and the applicability of existing airworthiness provisions and compliance verification methods were discussed. The results show that the composite airframe wall plate and thermal acoustic insulation blanket derived configuration can meet the compliance criteria proposed by the current airworthiness verification method, and the thermal acoustic insulation blankets effectively reduce the smoke specific optical density and smoke release velocity.
