Study of Effects of Gravity on Crystallization

The effect of gravity on the crystallization behavior of fluoride fibers is being investigated by performing fiber annealing experiments on NASA's KC-135 using commercial grade fibers donated by industrial partners. The successful observations of reduced formation of microcrystallites in reduced gravity of the parabolic flights will be repeated to confirm earlier results. The design and implementation of an automated sting assembly for use in space fiber drawing experiments will also be emphasized in this study.
