摘　　要：为进一步提高热防护服的综合性能,满足增加防护性和降低热应激的需求,构建了石墨烯气凝胶复合面料系统。通过不同的评价指标,在低辐射热环境下探讨了制备过程中氧化石墨烯水溶液的质量分数、石墨烯气凝胶的厚度、石墨烯气凝胶中是否添加碳纤维3个因素对复合面料系统热防护效果的影响。实验结果表明,与对照组相比,加入石墨烯气凝胶的复合面料系统有较好的热防护性能,可将人体产生热损伤的时间延长165%~318%,将产生二级烧伤时间延长87%~225%,将面料系统最大温差降低35.6%~63.9%;温升12℃的时间、温升24℃的时间和面料系统最大温差3个影响因素之间存在交互作用,而指标面料系统到达最高温度的时间在3个因素之间不存在交互作用,碳纤维因素主效应显著。To improve the comprehensive performance of thermal protective clothing and meet the needs of increasing thermal protection and reducing heat stress,a graphene aerogel composite fabrics system was developed.Based on different evaluation indices,the effects of mass fraction of graphene oxide solution during preparaton,thickness,and carbon fiber content of graphene aerogel on thermal protection of composite fabric system were investigated in a low radiation condition.The results show that the composite fabric system with graphene aerogel provides better thermal protective performance,with the time required to cause skin damage extending 165%-318%,the time required to generate skin burn prolonging for about 87%-225%,and the maximum temperature rise reducing 35.6%-63.9%.There are interactions among the three influencing factors for the indices time for temperature rise of 12℃,time for temperature rise of 24℃and the maximum temperature rise.Whilst the time to reach maximum temperature has no interaction with the three factors,the effect of carbon fiber content is significant.
