This Small Business Innovation Research (SBIR) Phase II project will establish the technical basis for large scale manufacturing of continuous glass fibers with well-controlled chemical composition and dimensions, from oxide materials which form inviscid melts. The process is based on the demonstrated ability to create and maintain liquids in an undercooled, non-equilibrium state at temperatures below the normal melting point. The viscosity of the liquid increases in the undercooled state, allowing glass fibers with unique properties to be formed from materials that normally do not support fiber pulling operations. In Phase I, the feasibility of producing fibers from materials with applications in infra-red optical transmission, fiber laser, and structural application was demonstrated. The Phase II research will scale-up production of fibers and provide materials to collaborating Phase III partners for applications R&D. The proposed Phase II research will provide advanced oxide glass fiber materials for fiber lasers, infrared transmission, and ceramic composites in the telecommunications, medical, turbine engine industries.

该小型企业创新研究（SBIR）第二阶段项目将为大规模制造具有良好控制化学成分和尺寸的连续玻璃纤维奠定技术基础，这些玻璃纤维来自形成非粘性熔体的氧化物材料。 该工艺基于已证明的在低于正常熔点的温度下产生和保持液体处于过冷、非平衡状态的能力。 液体的粘度在过冷状态下增加，允许由通常不支持纤维拉伸操作的材料形成具有独特性质的玻璃纤维。 在第一阶段，证明了从红外光传输、光纤激光器和结构应用材料生产光纤的可行性。 第二阶段的研究将扩大纤维的生产规模，并为第三阶段的合作伙伴提供材料，用于应用研发。 拟议的第二阶段研究将提供先进的氧化物玻璃纤维材料，用于光纤激光器，红外传输，以及电信，医疗，涡轮机发动机行业的陶瓷复合材料。
