Abstract:

The development and characterization of an improved ADL-4D6 silicasilica composite hardened antenna window material have been completed. A spall threshold in excess of 8000 taps for one inch thickness has been demonstrated, supported by determination of the dynamic equation of state. The design data level characterization program showed minimum room temperature tensile strengths of 5000 psi and nominal failure strain of 1, with significantly higher measured values at temperatures up to 1600 F.
