ARALL是一种由铝合金(含铝锂合金)薄板与纤维(通常的芳纶纤维)预浸料交替铺层经加温加压的层板材料,具有耐温、比强度高、疲劳性能和损伤容限好、耐环境作用、抗雷击、阻尼性能和成形加工性好等特点,是航空航天用新型结构材料。目前,荷兰、美国、德国等已在航空器上逐步推广应用,获得显著的技术效果和经济效益。为跟踪世界高科技发展,以满足我国航空航天事业发展的需要,北京航空材料研究所与有关单位协作开展同类结构层板材料的研制工作,并得到国家自然科学基金资助,现已取得可喜的阶段成果。该所为配合研制工作,由课题组与有关设计所共同翻译出版了《新型结构材料ARALL译文集(一)》,介绍了该材料的组成、制造、性
ARALL is a laminated material made of aluminum alloy (aluminum-lithium alloy) sheet and fiber (usually aramid fiber) prepreg laminated with heat and pressure, which has the advantages of high temperature resistance, high strength, fatigue resistance and Damage tolerance is good, environmental resistance, anti-lightning, damping properties and forming processability is good, is a new type of aerospace structural materials. At present, the Netherlands, the United States, and Germany have been gradually popularized and applied on aircraft to obtain significant technical and economic benefits. In order to keep track of the world’s high-tech development and meet the needs of the development of China’s aerospace industry, Beijing Institute of Aeronautical Materials, in collaboration with relevant agencies, has conducted research and development work on laminates of similar structure and obtained grants from the National Natural Science Foundation of China, Results. In order to cooperate with the research and development work, the research group and the design institute jointly translated and published the ARALL Translation Collection of New Structural Materials (I), and introduced the composition, manufacture and sexuality of the material
