Space environmental effects on LDEF composites: Leading graphite/epoxy panel, selected trailing edge specimens

The composite electronics-module cover for the leading edge (row D9) experiment M0003-8 was fabricated from T300 graphite/934 epoxy unidirectional prepreg tape in a multi-oriented layup. This panel contained thermal control coatings in three of the four quadrants with the fourth quadrant left uncoated as a control. The composite experienced different thermal cycling extremes in each quadrant due to the differing optical properties of the coatings. Results will be presented on microcracking and other Low Earth Orbital (LEO) effects on the coated panel substrate.

Survey of results from the Boeing modules on the M0003 experiment on LDEF

The Boeing Company provided specimens to be flown on the Long Duration Exposure Facility (LDEF) as part of the M0003 experiment. This hardware was for the M0003-8 and part of the M003-10 sub-experiments. These specimens were flown on the leading (tray D-9) and trailing (tray D-3) edges, and on trays D-8 (38 degrees from ram) and D-4. Some specimens were mounted in the Experiment Exposure Control Canisters.
