Book excerpt: Recent impact experiments conducted at Johnson Space Center supported a space-exposed flight instrument called the orbital debris collector (ODC) to see whether SiO2 acrogel performed adequately as a collector to capture cosmic dust particles and/or manmade debris, or whether additional development is needed. The first ODC was flown aboard the Mir for 18 months, while the second will be flown aboard a spacecraft (Stardust, to be launched in 1999) that will encounter the comet Wild 2 and return to Earth. Aerogels are highly porous materials that decelerate high-velocity particles without substantial melting or modifications to the particles' components; in other denser materials, these particles would melt or vaporize upon impact. The experimental data in this report must be considered somewhat qualitative because they are characterized by substantial, if not intolerable, scatter, possibly due to experimental difficulties in duplicating given sets of initial impact conditions. Therefore, this report is a chronological guide of the experimenters' attempts, difficulties, progress, and evaluations for future tests.

Book excerpt: This report presents the results of research undertaken to study various problems associated with hypervelocity capture of dust particles in aerogel. The primary topics investigated were the properties of shocked aerogel and the requirements for reliable capture of particles on the STARDUST mission. In particular, the viscosity of shocked aerogel has been an open question. The results presented here suggest that the viscosity of aerogel at high impact velocities is negligible, although there remains some uncertainty about lower velocities. The model adopted for viscosity treats the mixture of polymeric silica and decomposition products and finds that, for particle velocities of 6-7 km/s, the viscosity is similar to that typical of light gasses at STP. Expressions for the Hugoniot of aerogel as a function of density were also obtained from the available data. All aerogels of interest for cosmic dust collectors have very similar shock velocity-particle velocity Hugoniot curves. The strength behavior of aerogel for low-speed penetration was measured, but further work is needed to study the proper way to apply this to the issue of terminal deceleration of a dust particle. Preliminary calculations designed to maximize the penetration depths were performed to determine the required density of aerogel to reliably stop a particle in a 3 cm thickness of aerogel (the path length expected for a normal impact into the STARDUST collector). In order to stop a particle of density rho(sub p) and diameter d(sub p), the mean density of the aerogel collector should be no less than that given by the expression bar rho(sub 0) = 1.085 X 10(exp -4 )rho(sub p)d(sub p), for densities measured in g/ cu cm and the particle diameter measured in micrometers.

Available in PDF, EPUB and Kindle. Book excerpt: Aerogels are the lightest solids known. Up to 1000 times lighter than glass and with a density as low as only four times that of air, they show very high thermal, electrical and acoustic insulation values and hold many entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal and ceramic materials, etc. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation and household uses are being developed with an estimated annual market growth rate of around 70% until 2015. The Aerogels Handbook summarizes state-of-the-art developments and processing of inorganic, organic, and composite aerogels, including the most important methods of synthesis, characterization as well as their typical applications and their possible market impact. Readers will find an exhaustive overview of all aerogel materials known today, their fabrication, upscaling aspects, physical and chemical properties, and most recent advances towards applications and commercial products, some of which are commercially available today.

Book excerpt: This indispensable handbook provides comprehensive coverage of the current state-of-the-art in inorganic, organic, and composite aerogels – from synthesis and characterization to cutting-edge applications and their potential market impact. Built upon Springer’s successful Aerogels Handbook published in 2011, this handbook features extensive revisions and timely updates, reflecting the changes in this fast-growing field. Aerogels are the lightest solids known to man. Up to 1000 times lighter than glass and with a density only four times that of air, they possess extraordinarily high thermal, electrical, and acoustic insulation properties, and boast numerous entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to incorporate non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal, and ceramic materials. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation, and household uses are being developed. Readers of this fully updated and expanded edition will find an exhaustive source for all aerogel materials known today, their fabrication, upscaling aspects, physical and chemical properties, and the most recent advances towards applications and commercial use.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses polymeric and composite materials for aerospace industries and discusses some general qualities of aviation materials, e.g., strength, density, malleability, ductility, elasticity, toughness, brittleness, fusibility, conductivity, and thermal expansion. Metals and alloys have so far been best able to utilize their qualities almost to the maximum. The latest advancements in polymers and composites have opened up a new area of conjecture about how to modify airplanes and shuttles to be more polymeric and less metallic. Polymeric materials have been the focus of exploration due to their high strength-to-weight ratio, low cost, and a greater degree of freedom in strengthening the needed qualities. Strength, density, malleability, ductility, elasticity, toughness, brittleness, fusibility, conductivity, and thermal expansion are some of the general qualities of aviation materials that are taken into account. Aerospace Polymeric Materials discusses a wide range of methods with an outline of polymeric and composite materials for aerospace applications. Among the range of topics discussed are aerogel properties; polymeric welding; polymeric reinforcement, their properties, and manufacturing; conducting polymer composites; electroactive polymeric composites; and polymer nanocomposite dielectrics. In addition, a summary of self-healing materials is also presented, including their significance, manufacturing methods, properties, and applications. Audience This is a useful guide for engineers, materials scientists, researchers, and postgraduate students from industry, academia, and laboratories that are linked to polymeric composites.

This publication contains 36 papers taken from three symposia of COSPAR Scientific Commission B, which took place during the Thirty-first COSPAR Scientific Assembly, held in Birmingham, UK, during July 1996. The major areas covered by the symposia and which form this volume are as follows: the particulate space environment, problems in comparative planetology, and laboratory investigations relevant to planetology. Papers on the particulate space environment reflect advances in evaluation of the space environment, the deeper understanding of hypervelocity impact phenomena, and hold interest for the understanding of the natural environment and space debris. Papers on problems in comparative planetology investigate differences in impact melting on the surfaces of different planets, the geology of Alba Petra on Mars and attempts to interpret the geology of that region in terms of the geology of corona structures found on Venus. Papers concerning la
