Abstract
This proposal addresses the space optic community’s need for an optical bonding material with superior stability in the harsh space environment. Adhesives used in space must exhibit near-zero degassing, tolerate drastic temperature changes and be hardened to ionizing sources of radiation. The tolerance for these properties are restricted even further when applied to adhesives in the optical path, as is the case for solar cell coverglass adhesives. As the power systems have become more advanced, the limits of Dow Corning’s DC93-500 have been exceeded. Infoscitex proposes to develop a space grade optical bonding technique comprised primarily of a radiation-hardened silicate-like network combined with elastomeric linkages. The proposed silicate-elastomer hybrid bond (SEHB) will exhibit the following advantages over DC93-500: Enhanced resistance to radiation, optical transmittance and charge dissipation. Thermal shock durability and near-zero outgassing will also be demonstrated. Infoscitex is uniquely positioned to insert candidate bonded samples into ongoing radiation resistant coverglass development testing. Phase II prototype coverglass interconnected cells (CICs) fabricated with the SEHB technology will be delivered to AFRL or platform manufacturers for prequalification. Infoscitex has teamed with an optical products supplier and a solar array manufacturer to commercialize the SEHB technology after the SBIR Phase II.
