“…In order to solve this problem, it has been proposed that the use of inflatable structures could be deployed on the lunar surface [1,[5][6][7][8][9][10][11][12][13]. These structures would be composed of "soft" materials such as fabrics, foams, and elastomeric polymers instead of the traditional rigid composites and metal alloys [1,7].…”

As the Space Shuttle program ends, NASA is developing the next generation of space vehicles. These new concept designs will require new and innovative structural health monitoring capabilities. One way to solve this problem is with smart impact sensors that use triboluminescent materials. In 2011, the authors reported an 82% increase in the triboluminescence yield of europium dibenzoylmethide triethylammonium (EuD4TEA) by changing the starting material. It has been shown that introduction of dopants tends to enhance the triboluminescent light yield. Here we report the successful synthesis of a multivitamin doped europium tetrakis which appears to be spherical in shape. Inductively Coupled Plasma – Optical Emission Spectroscopy analysis showed the presence of 3.6% calcium, 0.62% magnesium, 0.1% iron, 0.01% copper and manganese. This new product has no shift in the triboluminescent or photoluminescent emission peaks, but only a change in the intensity. In addition, the doped EuD4TEA powder statistically emits more triboluminescence while having the same decay time. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…1) is a demonstration precursor prototype with a principal focus on ergonomic and human factors effects, but with continued associated structural development. Structural development (or evolution), includes such sections as floors, floor support beams, hatches, doors, airlocks and egress/ingress porches, access ways, as well as numerous other critical systems 1 . The initial HDU-DSH prototype was designed and fabricated at the Langley Research Center (LaRC) and consists of eight pie type sections, as can be seen around the upper hatch section in Fig 1. The initial prototype was referred to as Generation 1, or Gen 1, with the efforts outlined in this report being part of the Generation 2, or Gen2, prototype.…”

In support of NASA's Habitat Demonstration Unit -Deep Space Habitat Prototype, a number of evolved structural sections were designed, fabricated, analyzed and installed in the 5 meter diameter prototype. The hardware consisted of three principal structural sections, and included the development of novel fastener insert concepts. The articles developed consisted of: 1) 1/8th of the primary flooring section, 2) an inner radius floor beam support which interfaced with, and supported (1), 3) two upper hatch section prototypes, and 4) novel insert designs for mechanical fastener attachments. Advanced manufacturing approaches were utilized in the fabrication of the components. The structural components were developed using current commercial aircraft constructions as a baseline (for both the flooring components and their associated mechanical fastener inserts). The structural sections utilized honeycomb sandwich panels. The core section consisted of 1/8th inch cell size Nomex, at 9 lbs/ft 3 , and which was 0.66 inches thick. The facesheets had 3 plys each, with a thickness of 0.010 inches per ply, made from woven E-glass with epoxy reinforcement. Analysis activities consisted of both analytical models, as well as initial closed form calculations. Testing was conducted to help verify analysis model inputs, as well as to facilitate correlation between testing and analysis. Test activities consisted of both 4 point bending tests as well as compressive core crush sequences. This paper presents an overview of this activity, and discusses issues encountered during the various phases of the applied research effort, and its relevance to future space based habitats.
