第一章序言本章定义了“先进复合材料”这一技术名词,并广泛讨论了先进复合材料结构的连接接头,即对接头的承载效率、机械连接与胶接连接的优点和缺点、选择接头时应考虑的因素、胶接连接的特点以及表面准备等进行了评述。 1-0符号 E——接头总效率,无因次 E_L——承载效率,无因次 E_W——接头重量效率,无因次 L_C——被连接件能承受的载荷,磅 1-1先进复合材料的定义 L_i——接头能承受的载荷,磅 W_c——被连接件的重量,磅 W_i——连接件的重量,磅
Chapter I Foreword This chapter defines the technical term “advanced composite materials” and extensively discusses the connection joints of advanced composite structures, namely the carrying efficiency of joint, the advantages and disadvantages of mechanical connection and adhesive connection. When choosing joint The factors to be considered, the characteristics of the glued joint and the surface preparation are reviewed. 1-0 Symbol E - Total joint efficiency, dimensionless E_L - Bearing efficiency, dimensionless E_W - Joint weight efficiency, dimensionless L_C - Loaded load, pound 1-1 Advanced Composite Material definition L_i - load that the joint can bear, lb W_c - weight of the connected piece, lb W_i - weight of the connecting piece, pounds
