New and Improved Material for Expandable Structures

Title
New and Improved Material for Expandable Structures
Description
The initial objective of the program being conducted by GAC under Contract AF 33(616)-7854 is to establish the general requirements of expandable structures with respect to special and re-entry environment; review present materials research which may be applicable to expandable structures; and recommend areas and specific programs in which additional research is required. The initial effort was a study which would fulfill the above objective.
Upon completion of the initial study, the program was expanded to include four (4) specific programs involving research in the following areas:
1, Weaving of Stranded Metal Yarns 2. Film and Elastomer Permeability 3. Radiation Re-Entry Coating 4. High Temperature Protective Study
Tasks 1 and 3 have just commenced with respect to this program; however, there is sufficient scientific data to establish feasibility of accomplishing their objectives.
The permeability study is concerned with exposing polyvinyl fluoride; polyvinylidine fluoride, polytrifluoromonochloroethylene, and tetrafluoroethylene-hexafluoropropylene film to an ultraviolet source in a vacuum of approximately 10-6 Torr. These materials are being exposed to three different energy levels and changes in permeability, mechanical and chemical structure are being noted. A similar exposure and analysis will be conducted for a butyl, Viton, and Silicone elastomers.
In the high temperature protective study, radiation, insulation, ablation and combinations of methods were investigated and analyzed for use with expandable structures.
