- Description
- NASA/LaRC has a requirement for microspheres 300 mm or smaller, partially filled with water. These microspheres are to be embedded and uniformly distributed within a polymeric material. The specific heat of the resulting composite material is to be measured and the data and specimens delivered to NASA. The Contractor will be required to prepare a composite material comprised of water-containing microcapsules uniformly dispersed in a polymeric matrix. The specific requirements are as follows: 1)The microcapsules are to be no larger than about 200-300?m, but can also be substantially smaller than about 200?m. 2)The microcapsules will have a core-shell morphology with the core comprising as much volume as possible of the total capsule. 3)The capsule shell should be compatible with the polymeric matrix of the composite, compatible with water, withstand operating temperatures of about 20-400?F (-10 - 200?C), and pressures of about 275psia at 400?F. However, some of these materials requirements may not be strictly required in implementation to achieve desired composite performance. 4)The capsule core will be comprised of water and vapor in various ratios ranging from mostly water to mostly vapor. 5)The matrix material should withstand operating temperatures of about 20-400?F (-10 - 200?C) and internal pressures of about 275psia. The materials should further be able to withstand thermal cycling over the given temperature range for 3-5 cycles and a sustained period at maximum cycle temperature of about 30minutes. 6)Develop methods of preparing composite layups so that the microcapsules are uniformly dispersed in the matrix. 7)Characterize the thermal property measurements of formulated composites over the temperature range of 20-400?F (-10 - 200?C). Deliverables shall be as follows: 1) 3 samples of solid matrix material 2) 3 samples of matrix containing hollow microspheres 3) 3 samples of matrix containing ~50% volume water-filled microcapsules. 4) Characterization information of all materials The contractor shall deliver the samples to NASA LaRC not later than six (6) months after receipt of order (ARO). Deliverables shall be as follows: NASA/LaRC intends to purchase the microspheres from Southwest Research Institute, as they are the only known source capable of satisfying agency requirements. The hollow spheres are prototypes of a invention called the Heat Sponge that can store a lot of heat in a small amount of mass. These embedded heat sponges may enable better designs of integrated multifunctional structures for reusable launch vehicles being investigated in the Next Generation Launch Vehicle program. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on April 20, 2003. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
