本规范涵盖了由聚酰胺纸制成的蜂窝芯，蜂窝芯以块、片和有序形状的形式提供，蜂窝芯的单元为过度扩展的矩形配置。这种蜂窝芯通常用于要求在-67至+180摄氏度（-55至+82华氏度）温度范围内具有高强度和耐腐蚀性的粘结夹层结构，用于单曲率零件，但用途不限于此类应用。

This specification covers honeycomb core made of polymide paper sheets and supplied in the form of blocks, slices, and ordered shapes, the cells of the core being in an overexpanded, rectangular configuration.This honeycomb core has been used typically for bonded sandwich structures requiring high strength and corrosion resistance in the temperature range -67 to +180 degrees C (-55 to +82 degrees F), for use in single curvature parts, but usage is not limited to such applications.
