Advanced Manufacturing Processing to Produce Economical Ceramic Fibers

这个小企业创新研究第一阶段项目将开发一种生产SiC多长丝纤维的工艺，售价低于50美元/磅。美国工业对复合材料的需求非常迫切，需要一种经济的陶瓷/碳化硅（SiC）纤维来生产复合材料。世界陶瓷纤维，特别是碳化硅的供应主要由日本主导，其价格超过300美元/磅。SiC纤维的高成本、纤维性能限制和国外供应阻碍了许多工业、航空航天和国防应用。先进的创新制造工艺提供了生产优质小直径多丝SiC纤维的潜力，其价格不到当前价格的六分之一。该项目将开发非传统的独特化学气相沉积（CVD）工艺，用于多长丝SiC纤维的生产演示，确定其机械性能超过现有的SiC纤维，并利用操作数据来证明所有陶瓷纤维的最低成本。

This Small Business Innovation Research Phase I project will develop a process to produce SiC multifilament fiber to sell at less than $50/lb. U.S. industry has a critical need for composite materials that require an economical ceramic/silicon carbide (SiC) fiber to produce the composite. World supply of ceramic fibers and particularly SiC is dominated by Japan whose price is in excess of $300/lb. Many industrial, aerospace and defense applications are impeded by the high cost of SiC fibers, fiber property limitations and foreign supply. Advanced innovative manufacturing processing offers the potential to produce a superior high quality small diameter multifilament SiC fiber for less than one sixth the current price. This program will develop nontraditional unique chemical vapor deposition (CVD) processing for the production demonstration of multifilament SiC fiber, establish that mechanical properties exceed existing SiC fibers and utilize operational data to demonstrate the lowest cost of all ceramic fibers.
