过去二十年间常规战争最根本的转变之一是日益趋向于加强空中机动性,结果导致战术上依靠直升飞机来提供部队和装备的调动和支援。无疑,在这种趋势中,不仅需要重量轻、成本有效和可靠的直升飞机,而且需要用直升飞机运载重量轻和成本有效的野战装备和物资。因此,为了这些用途;极需提供具有高强度和轻重量的材料。近年来,陆军越来越多地研究和采用纤维复合材料。这些材料不仅改进的性能超过了普通结构材料的性能,而且同样重要的是其重量较轻,在机动作战中能明显节省能源。陆军应用感兴趣的是纤维复合材料,它具 One of the most fundamental shifts in conventional wars over the past two decades has been the growing tendency to strengthen air mobility, resulting in the tactical reliance on helicopters to provide mobility and support for troops and equipment. Undoubtedly, this trend requires not only light, cost-effective and reliable helicopters, but also the need to use helicopters to carry light-weight and cost-effective field equipment and supplies. Therefore, for these purposes, it is highly desirable to provide materials with high strength and light weight. In recent years, the Army has increasingly studied and adopted fiber composites. These materials not only improve performance beyond the performance of common structural materials, but just as importantly as their lighter weight and significant energy savings in maneuvering. Army applications are interested in fiber composites, it has
