| 内容記述 | The objective of this project is to design and build a laboratory scale extruder and with it to fiberize 5000 continuous feet of silicon-carbide-nitride precursor resin. Subsequently the objective is extended to include the cross-linking and pyrolysis of approximately 100 feet of the resin fiber. The extruder is designed to accommodate approximately 1 cubic centimeter samples at accurately controllable rates corresponding to take-up from a single orifice of a 25 micron fiber at speeds in the 1000 feet/minute region. Positive feed delivery is achieved with a cylinder and piston driven by a geared down electric motor. Gear reduction is achieved primarily with off-the-shelf parts. Over 5000 feet of fiber, 20 to 30 micron diameter, are spun from precursor resin samples. The formation of continuous silicon carbide/silicon nitride fiber appears to be feasible. |
