从环境因素对复合材料作用和大展弦比结构影响等方面分析了长航时无人机机体结构复合材料在服役环境中的损伤。结合目前国内外研究现状,扼要叙述了环境因素对长航时无人机机体结构复合材料的影响研究领域当前的主要需求,提出了针对未来研究工作的若干建议。包括应以长航时无人机机体结构典型碳纤维增强树脂基复合材料和涂层体系为主要研究对象,开展跟随无人机的暴露试验和实验室模拟加速试验,研究复合材料在环境和载荷耦合作用下的力学性能变化,确定机体结构典型复合材料的损伤规律等。
From the environmental factors on the role of composite material and the effect of large aspect ratio structure and other aspects of long flight UAV body structure composite materials in service environment damage. Combining with the current research situation both at home and abroad, the author briefly describes the current main requirements of the field of research on the impact of environmental factors on the composite structure of UAV body structure when long-haul, and puts forward some suggestions for future research work. The main research object should include the typical CFRP composite and coating system of UAV structure of long voyage, carry out UAV exposure test and laboratory simulation acceleration test, and study the relationship between environment and load coupling Mechanical properties under the changes, to determine the structure of the typical composite material damage laws.
