This specification covers the requirements for adhesives in film form for bonding metal facings to metal cores and to metal components of sandwich panels which are intended for use in primary and secondary structural airframe parts that may be exposed to temperatures up to 500°F (260°C).
This specification covers the material and process requirements for fabricating sandwich radomes having hot-melt, addition-reaction polyimide-resin-impregnated quartz cloth shells and polyimide-resin syntactic foam cores.
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 specification covers the requirements for nonperforated nylon paper base plastic honeycomb core material for aircraft structural applications, including exterior parts such as radio and radar antenna housings.
This specification covers the requirements for glass fabric base plastic honeycomb core materials for aircraft structural applications, including aircraft exterior parts, such as radio and radar antenna housings, and other parts.
This specification covers the material and process requirements for fabricating sandwich radomes having polyimide-resin-impregnated quartz cloth shells and polyimide-resin syntactic foam cores.
This specification covers honeycomb core made of polyamide paper sheets and supplied in the form of blocks, slices, and ordered shapes, the cells of the core being in an overexpanded, rectangular configuration.
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 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.
This document describes a manufacturing method for processing unidirectional carbon fiber/epoxy resin impregnated sheet and tape into multi-ply broadgoods and tape produced on an automated cross-plying machine. Broadgoods or tape of two or more ply configurations may be processed, where ply orientations of 0°, 45°, 90°, and 135° (as examples) may be automatically layed in a programmed sequence. In all configurations, the 0° ply direction is parallel to the length of the broadgoods roll or sheet, or tape.
This specification covers an adhesive compounded from modified epoxy resins in ready-to-use film supplied in rolls or sheets, either supported by mat or by woven monofilaments or unsupported.
