Energy Efficient, Incrementally Scalable, Continuous Basalt Fiber Manufacturing Process (Final Technical Report)

Abstract

This project focused on new materials, bushing materials, that had the ability to produce continuous basalt or glass fiber. The original scope of the project was designed to identify bushing materials and produce fiber, but that scope did change during the program. The team put significant work into bushing material development in the place of producing fiber. The final bushing materials had to be able to produce fiber and the final sets of the project saw single strands of fiber be produced. The final materials selected was a unique MMC bushing composition. Using advanced chemistry, the interface chemistry was tailored between metallic and ceramic powders. Powders and fibers were consolidated using cold isostatic pressing and electrified ceramic hot pressing to form a near net shape composite bushing.
