Electrostatic discharge control is vital for the health of any spacecraft. Exposure to charged particles in a space enviroment can lead to large charge differences across the craft, that, if no mechanism for controlled discharge is present, can destroy mission critical equipment. The preferred way of ESD control is to use conducting thermal control coatings. These coatings combine the ability to r ...

Inflatable or self-deployable systems offer the only practical way to achieve space deployed antennas with low mass at large aperture. In this Phase I program, open-celled rigid polyurethane foams were developed for use in self-deploying antenna structures. Advantages of such a system relative to current systems include high volumetric efficiency of packing, inherent restoring force, low (or no) o ...

70307 Many DOE sites have the need to monitor radionuclide contamination in surface water, groundwater, soils, and the vadose zone. In many cases, a real-time and/or remote monitoring capability is desired. Existing site characterization procedures typically involve the collection and shipment of samples to an off-site laboratory, which leads to costly delays in site remediation as ...

The concentration of carbon dioxide in exhaled breath is 3.8%; a concentration of 2% causes deepened breathing, and 4% causes a marked increase in respiration. These higher concentrations of CO2 also cause drowsiness and can be unsafe. Therefore, it is desirable to monitor the concentration of CO2 in exhaled breath to guarantee the safety of an astronaut in the dangerous extravehicular environment ...

"Three-dimensional textile reinforcement architectures with straight in-plane fibers and optimized through thickness fiber content are considered as efficient solutions for the next generation of light weight, damage tolerant, high strength compositesallowing for cost-effective manufacturing solutions. The 3-D weaving process is gentle to the fibers, thus making automated fiber optic sensor insert ...

70360 The increased use of environmentally-friendly wind energy would help reduce pollution and the emission of hydrocarbons. Wind energy is a fast growing business area, with state-of-the-art turbine blades approaching design limits based on glass reinforced composite materials. New materials and blade design approaches that utilize higher performance carbon fibers would enable lighter mate ...

"3TEX, Inc., the Center for Composite Materials at the University of Delaware, and the University of Rhode Island propose to further develop 3-D orthogonal woven composite materials for armor applications. We will use a combined approach of new materialsdevelopment, instrumented high strain rate and ballistic testing, and numerical impact simulation, to further phase 1 results on S-2 glass structu ...
