1989年9月航空材料及热工艺标准化技术归口单位主持召开了航空工业标准审定会,审查并通过了“夹层结构用耐久铝蜂窝芯材规范”、“拉伸法制造耐久铝蜂窝芯材工艺规范”及“胶接裂纹扩展力测试方法”三项标准。这三项是航空工业需要的重要标准,是在研究、设计和生产中多年实践积累的数据基础上并参考国外先进标准制定的。“夹层结构用耐久铝蜂窝芯材规范”的技术性能要求相当于美国
September 1989 Aeronautical Materials and Thermal Technology Standardization Technical focal point presided over the aviation industry standards review will review and adopted the “sandwich structure with durable aluminum honeycomb core norms”, “Stretch method to create durable aluminum honeycomb core process specification ”And“ glue crack propagation force test method ”three criteria. These three items are important standards required by the aviation industry and are based on data accumulated through years of practice in research, design and production, with reference to advanced foreign standards. The technical performance requirements of “Durable Aluminum Honeycomb Core Materials for Sandwich Structures” are equivalent to those of the United States
