S-3A Graphite/Epoxy Spoiler Development Program.

Abstract

Material selection, structural analysis, manufacturing and tool development and verification testing results are presented for an S-3A graphite spoiler. The spoiler is designed to be a cost competitive lightweight replacement for the metal spoiler, and is to be fit and functionally interchangeable with the existing part. The spoiler will be of sandwich construction with graphite/epoxy faces and non-metallic core. Narmco 5209/T300 graphite/epoxy tape material which has a 260F curing temperature was selected for the skins and fiberglass (HRP) core will be used. Problems encountered during the fabrication of 12 manufacturing development specimens and 118 design verification specimens are outlined and solutions explained. A manufacturing operational sequence describes the major fabrication operations. Design verification testing resulted in a design modification to the spoiler because of loss of strength and stiffness when the sandwich specimens were co-cured. Detail assembly drawings are included.
