SPACECRAFT-BORNE ELECTROMAGNETIC RADIATION REFLECTOR STRUCTURE

摘要

ELECTROMAGNETIC RAID AT ION REFLECTOR STRUCTURE A deployable, spacecraft-borne, reflector structure comprises: a reflector sheet 12 having a reflecting surface and being formed from a plurality of plies; each ply includes at least two layers of graphite fiber reinforced epoxy; the fibers in respective GFRE layers of each ply are oriented to provide quasi-isotropic properties in that ply; an annular rib is bonded to a rear surface of the reflector sheet at the periphery of the sheet; the rib includes members disposed to present a U-shaped cross-section; and each of the rib members also includes a plurality of plies and is of construction like that of the reflector sheet.
