中文摘要:复合材料的电性能相比铝、钛合金之类的金属材料差别很大,且是各向异性的。其有效电导率比金属材料小得多,用复合材料制成大型飞机蒙皮后,将大大降低蒙皮隔离外部电磁场的屏蔽效能和传导电荷的能力。复合材料整体油箱在雷电、静电防护及电荷传导以及油箱内设备电磁防护设计方面不同于金属材料,有其特殊的设计要求和方案。
英文摘要:The electronic performance of composite is different from that of aluminum and titanium, and it is anisotropic. The effective conductance for composite is less than that of the metal. The large size aircraft panel made from composite will reduce greatly the the shielding and conducting capacities of the skin to insulate the exterior electromagnetic wave. Composite integral tank is different from metal material in lightning protection, electrostatic protection, charge conduction and electromagnetic protection devices in fuel tank. It has special design requirements and schemes.
