Abstract:

This final report is the culmination of a 16 week effort, the Advanced 3D Fabrication Techniques Program A3DFT. The fundamental objective of A3DFT was to prove the feasibility of fabricating a relatively large, cone- frustum shaped, ablative, antenna window from a 3D quartz yarn reinforced, silica material. This material, AS-3DC, is a further development of AS-3DX which was developed on previous programs. AS-3DX antenna windows are small and fabricated from simple, block-shape billets. The large, cone frustum-shaped, antenna window developed here represent a substantial advance in the state of the art. The program objectives were successfully fulfilled. Three full-scale AS-3DC frusta were woven, impregnated, machined, and the resulting parts characterized. The data indicate a superior ceramic antenna window material would ultimately result. Areas for improvement were identified and recommendations made for any subsequent development of the material. This report documents all the tasks which were accomplished. A design data package is included. The design data are representative of AS-3DC in its initial phase of development and improvement is a certainty for subsequent AS-3DC frusta.
