1.1 本规范涵盖了用于修复耐用、刚性壁、可重新定位结构的夹芯板的环氧树脂系统的要求。它必须能够在现场环境中使用，并且不需要使用特殊设备，如高压灭菌器或压力机。本说明书涵盖的环氧树脂体系应可用于同时浸渍湿铺层复合蒙皮和将蒙皮粘合到基底蜂窝芯上。材料应能承受54°C至93°C（65°F至199°F）的温度和高相对湿度，以及预期在使用中遇到的应力、温度和相对湿度的组合。 1.2 如果只给出国际单位制单位或先给出国际单位制单位后给出英寸，则以国际单位制单位陈述的值应被视为标准值。磅单位；如果首先给出英磅单位，然后给出国际单位制单位，则英磅单位应被视为标准单位。 1.3 以下安全危害警告仅指本说明书中描述的试验方法。 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。======意义和用途====== 5.1 用于修复耐用、刚性壁、可重新定位的遮蔽物的复合蒙皮夹芯板的环氧树脂系统必须具有机械性能水平和耐环境性的组合，以确保蒙皮和蒙皮-芯粘合剂在暴露于恶劣气候条件下时的长期耐久性。此外，这些环氧材料必须具有允许其在各种修复场景和环境中使用的可加工性特征。 5.2 预期用途- 符合本说明书的环氧树脂系统旨在用于维修现场水平的蜂窝板的修复。该材料预期与SAE-AMS-C-9084玻璃布一起使用。 5.2.1 这是一份采购环氧系统的采购控制文件，设计者应意识到此处规定的测试值是基于使用特定玻璃进行的测试-树脂复合材料粘附，不得用于设计数据。 5.2.2 本说明书涵盖的环氧树脂体系不打算用于夹层结构的生产粘合。

1.1 This specification covers the requirements for an epoxy resin system intended for the repair of sandwich panels for durable, rigidwall, relocatable structures. It must be usable in a field environment and shall not require the use of special equipment such as autoclaves or presses. The epoxy system covered by this specification shall be usable for simultaneous impregnation of a wet-layup composite skin and bonding of that skin to a substrate honeycomb core. The material shall withstand exposure to temperatures from −54 °C to 93 °C (−65 °F to 199 °F) and high relative humidity, and also the combination of stress, temperature, and relative humidity that are expected to be encountered in service. 1.2 The values stated in SI units are to be regarded as standard where only SI units are given or where SI units are given first followed by inch-pound units; where inch-pound units are given first followed by SI units, the inch-pound units are to be regarded as standard. 1.3 The following safety hazards caveat refers only to the test methods described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Epoxy resin systems used in the repair of composite skin sandwich panels for durable, rigidwall, relocatable shelters must have a combination of mechanical property levels and environmental resistance that will assure long-term durability of the skins and the skin-to-core adhesive bonds when exposed to severe climatic exposures. In addition, these epoxy materials must have processability characteristics that permit their use in a variety of repair scenarios and environments. 5.2 Intended Use— Epoxy systems conforming to this specification are intended for use in the repair of honeycomb panels at the maintenance field level. The material is intended for use with SAE-AMS-C-9084 glass cloth. 5.2.1 This is a procurement control document for the procurement of the epoxy system and designers shall be aware that the test values specified herein are based upon tests performed with specific glass-resin composite adherends and shall not be used for design data. 5.2.2 Epoxy systems covered by this specification are not intended for use in production bonding of sandwich construction.
