This work investigates the aerosols emitted from carbon fibre-reinforced epoxy composites (CFC) incorporating nanomaterials (nanoclays and nanotubes), subjected to simultaneous fire and impact, representing an aeroplane or automotive crash. Simultaneous fire and impact tests were performed using a previously described bespoke testing methodology with the capability to collect particles released from the front/back faces of the impacted composites plus the effluents. In this work the methodology has been further developed by connecting the Dekati Low Pressure Impactor (DLPI) and Mini Particle Sampler (MPS) sampling system in the extraction chimney. The aerosols emitted have been characterized using various devices devoted to the analysis of aerosols. The influence of the nanoadditives in the matrix on the number concentration and the size distribution of airborne particles produced, was studied with a cascade impactor in the 5 nm–10 μm range. The morphology of the separated soot fractions was examined by SEM. The measurement of aerodynamic size of particles that can deposit in human respiratory tract indicate that 75% of the soot and particles released from CFC could deposit in the lungs reaching the bronchi region at a minimum. There was however, a minimal difference between the number particle concentrations or particle-size mass distribution of particles from CFC and CFC containing nanoadditives. Moreover, no fibres were found in the effluents.

这项工作调查了碳纤维增强环氧树脂复合材料 (CFC) 释放的气溶胶，这些复合材料包含纳米材料（纳米粘土和纳米管），同时受到火灾和冲击，代表飞机或汽车坠毁。使用先前描述的定制测试方法进行了同步燃烧和冲击测试，该方法能够收集从受影响的复合材料的正面/背面释放的颗粒以及流出物。在这项工作中，通过在提取烟囱中连接 Dekati 低压冲击器 (DLPI) 和迷你粒子采样器 (MPS) 采样系统，进一步开发了该方法。排放的气溶胶已使用各种专门用于气溶胶分析的设备进行了表征。使用 5 nm–10 μm 范围内的级联撞击器研究了基质中的纳米添加剂对产生的气载颗粒的数量浓度和尺寸分布的影响。通过 SEM 检查分离出的烟灰部分的形态。可沉积在人体呼吸道中的颗粒的空气动力学尺寸的测量表明，从 CFC 释放的烟灰和颗粒中有 75% 可沉积在肺部，至少到达支气管区域。然而，来自 CFC 和含有 CFC 的纳米添加剂的颗粒的数量颗粒浓度或颗粒大小质量分布之间存在最小差异。此外，在流出物中没有发现纤维。通过 SEM 检查分离出的烟灰部分的形态。可沉积在人体呼吸道中的颗粒的空气动力学尺寸的测量表明，从 CFC 释放的烟灰和颗粒中有 75% 可沉积在肺部，至少到达支气管区域。然而，来自 CFC 和含有 CFC 的纳米添加剂的颗粒的数量颗粒浓度或颗粒大小质量分布之间存在最小差异。此外，在流出物中没有发现纤维。通过 SEM 检查分离出的烟灰部分的形态。可沉积在人体呼吸道中的颗粒的空气动力学尺寸的测量表明，从 CFC 释放的烟灰和颗粒中有 75% 可沉积在肺部，至少到达支气管区域。然而，来自 CFC 和含有 CFC 的纳米添加剂的颗粒的数量颗粒浓度或颗粒大小质量分布之间存在最小差异。此外，在流出物中没有发现纤维。来自 CFC 和含有 CFC 的纳米添加剂的颗粒的数量颗粒浓度或颗粒大小质量分布之间的最小差异。此外，在流出物中没有发现纤维。来自 CFC 和含有 CFC 的纳米添加剂的颗粒的数量颗粒浓度或颗粒大小质量分布之间的最小差异。此外，在流出物中没有发现纤维。
