ASTM E865-12

Standard Specification for Structural Film Adhesives for Honeycomb Sandwich Panels

ABSTRACT
This specification covers structural film adhesives used for bonding honeycomb sandwich panels consisting of an aluminum alloy bonded to a nonmetallic core, edge attachments, and other components, and for new production or depot repair. The adhesive shall be manufactured in film form from a thermosetting compound suitable for forming bonds that can withstand long exposures to a range of temperatures and combinations of stress, temperature, and relative humidity encountered during service. The adhesive may be pure or consist of a carrier impregnated with adhesive and shall be uniform in appearance, with a weight in the range specified. Tests for shear, peel, durability, tensile strength, and storage life shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers film adhesives for bonding of honeycomb sandwich panels. The adhesives are used for new production or depot repair. The adhesives shall be suitable for forming bonds that can withstand long exposures to temperatures from −55 to 93°C (−67 to 200°F) and also withstand the combinations of stress, temperature, and relative humidity expected to be encountered in service. The adhesives shall be used for bonding aluminum alloy facing to nonmetallic core, edge attachments, and other components of a sandwich panel.  
1.2 The values stated in SI units are to be regarded as the 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 regarded as the standard.  
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
