This book was released on 2009-01-15 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference proceedings are discussing the latest developments in the area of the effects of the space environment on materials and structures and the ways to prevent and/or reduce them. The effects of various space environment factors like atomic oxygen, vacuum ultraviolet radiation, charging, micrometeoroids, meteoroid showers, etc. on materials and structures in various space conditions are discussed. In addition the ways to prevent these effects or reduce them through protection by coatings or modification of affected surfaces are considered in the book. The discussions on development of predictive models of material erosion that will allow the materials engineers and designers of future spacecraft to evaluate materials' behavior is continued from the past meetings.

This book was released on 2018-09-25 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of its high reactivity, atomic oxygen causes surface erosion on polymeric materials. although the reaction efficiency depends on the chemical structure of the polymer. We have found an organotin compound, bis(triphenyltin) oxide (BTO), which has an unusually high solubility in solutions of a number of commercial high performance polymers. Films of these polymers containing BTO showed a substantial reduction in erosion by atomic oxygen when compared with films of the pure material. Analysis has shown that in the presence of atomic oxygen, erosion of the exposed surfaces of the BTO-containing films leaves a residual protective tin oxide coating . Since the additive is uniformly distributed throughout the polymeric material, any break or puncture in the protective coating is "healed" by the material below. Samples were exposed to the environment of the low earth orbit (LEO) on two Space Shuttle flights, STS-46, in June of 1992, and STS-51 in September of 1993. The analysis of these samples has been reported previously. For both flights, the samples were small (1.3 cm and 1.9 cm respectively) thus limiting the scope of analysis. In the research under this cooperative agreement, films of a polyetherimide, were exposed to the LEO environment on Space Shuttle flight STS-85 in August of 1997 as part of the Evaluation of Space Environment and Effects on Materials (ESEM) experiment. The polyetherimide chosen is available commercially as Ultem, registered to the General Electric Company. Films of pure Ultem, Ultem with 10% BTO by mass, and Ultem with 20% BTO by mass were exposed in the ram direction for 40 hours during STS-85. Ultem has a Tg of 215 deg C and is soluble in common chlorinated solvents. Granules of the polymer were dried at 120 deg C, but otherwise were used as received. Films were cast on a glass plate from a solution of the polymer in a 60/40 (w/w) mixture of chloroform and 1,1,2,2-tetrachloroethane. The plate was placed in a dust-free box for

Gonzalez and published by . This book was released on 2002 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymeric materials offer many advantages for low Earth orbit applications including ease of processing and reduced payload-to-orbit costs derived from a reduction in weight. However, over the last two decades it has been well established that polymers used in the construction of space vehicles undergo severe degradation resulting in reduced spacecraft lifetimes. These materials degrade because spacecraft surfaces must endure a high atomic oxygen (AO) flux, bombardment by low and high-energy charged particles, and thermal cycling along with the full spectrum of solar radiation. Many studies have been conducted in an effort to determine the mechanism of degradation primarily caused by surface reactions with oxygen atoms. Unfortunately, these studies have all been carried out after exposing these highly reactive surfaces to air prior to analysis, thus introducing artifacts that do not represent the true effect of the space environment.
