摘　　要：为提升干式潜水服内胆的隔热性能,并探究气凝胶复合材料在潜水服内胆中的水下应用潜力。选择絮片型、发泡型及非织造布型气凝胶复合材料,采用绗缝工艺技术模拟材料在水下的受压状态,研究其在压缩状态下的隔热性能,然后,制作潜水服内胆,通过暖体假人实验及真人水下实验测试其隔热性能。结果表明,絮片型气凝胶复合材料的水下适用性优于絮片型新雪丽棉;发泡型及非织造布型气凝胶复合材料的热阻受压强影响小,也较适用于水下环境;在真人实验过程中,潜水员的核心温度始终大于37℃,证明所研制的气凝胶复合材料内胆具有良好的水下隔热效果。研究结果可为受压环境下防护服隔热材料的应用方法提供指导建议。Objective This research aims to investigate the potential application of aerogel composite materials for enhancing the thermal insulation performance of dry diving suit liners underwater.Through meticulous experimentation conducted at both fabric and garment levels,this research aims to assess the thermal insulation capabilities,tailored for garment application.Employing sophisticated seam-sealing techniques,the behavior of these materials under compression in underwater conditions are to be simulated to evaluate alterations in thermal insulation performance.This comprehensive methodology seeks to elucidate the optimal utilization of aerogel composite materials,providing valuable insights into enhancing thermal insulation in diving suits,particularly in the challenging low-temperature,high-pressure environments often encountered during underwater operations.Method Experimental samples consisted of various aerogel composite materials known for their lightweight and superior thermal insulation properties.These are in the forms of foam,nonwoven fabric,and flake-type aerogel composites,along with a conventional polyester fiber cotton,specifically the C-type Thinsulate from 3M Corporation,used in dry diving suit liners.Fabrication involved combining these materials into a three-layered fabric system,maintaining consistency in outer and inner layer materials.Testing methodologies included sweating hot plate experiments for thermal resistance assessment and simulated compression design to simulate underwater pressure conditions.Additionally,sweating manikin method and underwater human subject trials were conducted to evaluate insulation performance in practical scenarios.Results Thermal performance analysis provided valuable insights into the behavior of various fabric systems.Significant thickness variations were observed among the samples before seaming,with flake-type materials displaying the highest initial thickness due to their relaxed state.After seaming,these materials experienced substantial thickness reduction
