This specification establishes the acceptance criteria and inspection requirements for adhesive-bonded sandwich structures including the metal-to-metal bonding found in these structures, but usage is not limited to such applications and each application should be considered individually.
This recommended practice describes the materials, related equipment, and particular processing techniques utilized in process science curing of composite hardware where pressure is imparted specifically to the resin of curing composites. Included as Appendix "A" to this ARP is a discussion of the particular techniques developed for a processing science philosophy which has consistently produced void and porosity-free, large area, thick composite structures.
This specification covers one type of glass cloth impregnated with a heat-reactive, addition-cure, thermosetting, polyimide-resin system, the resin to be supplied in a "B" stage condition for low flow and press cure at 40 - 100 psi (275 - 690 kPa) or vacuum/autoclave processing.
This specification and its supplementary detail specifications cover organic fibers in the form of cloth impregnated with epoxy resin, the resin to be supplied in a "B" stage condition.
This recommended practice describes the materials and procedures for cleaning aluminum alloy detail parts and low-alloy steel parts (other than corrosion resistant steel) prior to structural adhesive bonding operations.
