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 inspection and testing of the epoxy system shall be classified as qualification tests and quality conformance tests. The following test methods shall be performed to conform to the requirements specified: tensile lap shear strength; apparent horizontal shear strength; and flatwise tensile strength.
