Advanced Manufacturing Processing to Produce Economical Ceramic Fibers

这个小型企业创新研究第一阶段项目将开发一种生产碳化硅复丝纤维的工艺，以低于50美元/磅的价格出售。美国工业对复合材料有着迫切的需求，这种材料需要一种经济的陶瓷/碳化硅(SIC)纤维来生产复合材料。世界陶瓷纤维尤其是碳化硅的供应主要由日本主导，日本的价格超过每磅300美元。由于碳化硅纤维的高成本、纤维性能限制和国外供应，许多工业、航空航天和国防应用受到阻碍。先进的创新制造工艺提供了以不到当前价格六分之一的价格生产优质小直径复丝碳化硅纤维的潜力。该项目将为多丝碳化硅纤维的生产示范开发非传统的独特的化学气相沉积(CVD)工艺，确定其机械性能超过现有的碳化硅纤维，并利用运行数据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.
