Abstract:

This specification covers two-part paste adhesives for bonding foam core sandwich panels. The adhesive may be used for new production or depot maintenance. The adhesive should be suitable for forming bonds that can withstand long-term exposure to temperatures, and also withstand combinations of stress, temperature, and humidity. The adhesives shall be used for bonding aluminum alloy facing to foam core, inserts, edge attachments, and other components of a foam cored sandwich panel. Materials shall be tested and shall conform to the material requirements, working characteristics; and to the specified values of curing time, temperature, and pressure; mix ratio, storage life, adhesive life, humidity exposure, and salt spray exposure.

Significance and Use:

This specification is intended to provide information on the properties of adhesives, and the test methods required to evaluate adhesives to be used in the production bonding of aluminum alloys to foam core materials for the manufacture of tactical shelters.

Scope:

1.1 This specification covers two-part paste adhesives for bonding foam core sandwich panels. The adhesive may be used for new production or depot maintenance. The adhesive should be suitable for forming bonds that can withstand long term exposure to temperatures from 55 to 71°C (67 to 160°F) and also withstand combinations of stress, temperature, and humidity expected to be encountered in service. The adhesives shall be used for bonding aluminum alloy facing to foam core, inserts, internal aluminum framing members, and other components of a foam cored 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 be 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.
