 | A space environment exposure test has been performed on samples of Cloud White Tedlar with a multi-layer thin-film coating on the surface applied by Optical Coatings Laboratory, Inc. (OCLI) representing potential spacecraft applications. This test was performed to simulate a LEO ultraviolet (UV) exposure on a subset of samples representative of a piece of space hardware that had inadvertently been exposed to water. A test was needed to provide data ... |

| A space environment exposure test has been performed on a variety of samples of Cloud White Tedlar with a multi-layer thin-film coating on the surface applied by Optical Coatings Laboratory, Inc. (OCLI) representing potential spacecraft applications. This test was performed to evaluate new coating formulations. The Tedlar coated with the new formulations was compared with previously coated Tedlar material. For the coated Tedlar on foam samples, the Ta205/ZrO2 configuration appeared ... |

| Cloud White Tedlar with a multi-layer, thin-film coating on the surface applied by Optical Coatings Laboratory, Inc. (OCLI) is being investigated for potential spacecraft applications. Space environment exposure tests have been performed on a variety of samples exposed to simulated Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) conditions. The Space Environmental Effects Chamber used to provide the simulation of the LEO and GEO space environment contains a 2500-W xenon ... |

| Inflatable structures are being developed for use in space to take advantage of the potential for lower packaging volumes and lighter weights. These structures may consist of thin polymer membranes as well as more robust inflatable, then rigidizable, structural elements. For space applications, it must be shown that the materials can tolerate the orbital environment. This includes the effects of solar radiation and electron/proton radiation ... |

|
| Materials being considered for use in thin-film applications of inflatable structures were exposed to a simulated space environment representing a 5-year Low Earth Orbit (LEO) and also to a 5-year Geo- synchronous Orbit (GEO) . Solar absorptance and tensile test measurements were performed, pre- and posttest. The materials consisted of various thin polymer foils, including 0. 0005-in. bare and metallized Kapton E, LaRC-CPl, LaRC-CP2, FEP Teflon, Triton conductive COR, and ... |

|
| A passive tray was flown on the Effects of Oxygen Interaction with Materials experiment on STS-46 (EOIM-III) with 82 samples from The Aerospace Corporation. A variety of advanced materials related to potential uses on future spacecraft were included for evaluation representing optical coatings, lubricants, polymers, composites, carbon-carbon composite protective coatings, graphite protective coatings, thermal-control materials, and some samples of current materials. An overview of the available results from the investigations ... |

|
| Silver-backed fluorinated ethylene propylene Teflon (Ag/FEP) thin film material was used for thermal control in many locations on the Long Duration Exposure Facility (LDEF). The Ag/FEP registered the effects of atomic oxygen, solar ultraviolet radiation, meteoroid and debris impacts, thermal cycling, and contamination. This report summarizes the post-flight condition of the Ag/FEP, compares the results with performance on other spacecraft, and presents lifetime estimates for use under a variety of ... |

|
| Cumulative space environmental effects on Ag/FEP were a function of exposure orientation. Samples from 19 silvered Teflon (Ag/FEP) thermal control surfaces recovered from the Long Duration Exposure Facility (IDEF) have been analyzed to determine changes in this material as a function of position on the spacecraft. Although solar absorptance and infrared emittance of measured thermal blanket specimens are relatively unchanged from control specimen values, significant changes in surface morphology, composition, ... |

| A variety of materials were exposed to the low Earth orbit space environment on shuttle flight STS-8 as a part of NASA's Effects of Oxygen Atoms Interaction with Materials experiment. These materials include carbon and graphites, optical materials, organic and metal films, Kevlar and fiberglass fabric, and high-temperature coatings. The effects noted on these materials included oxidative erosion of the carbon and graphite, loss of tensile strength for the Kevlar ... |
