Abstract
Samples consisted of JSC-1 regolith simulant, melted purified sulfur and glass fiber hand-drawn from regolith were cast and tested in a four-point bend test. Stress and deflections of the control samples (without glass fibers) and samples containing 1% glass fibers by mass were made. The glass fibers made from melted JSC-1 simulant, were mainly produced by hand-draw process. Initial test results showed that the ultimate strength can significantly improve with the addition of fiber glass, derived from the lunar regolith simulant. Using a mathematical code created by Langley Research Center, the radiation shielding effectiveness of sulfur/regolith concrete and other composite materials were analyzed. The mathematical code is a good tool to compare the radiation shielding effectiveness of different materials. This comparison was presented in this paper.
