SBIR Phase II: "RT Photocurable Preceramic Polymers to Si3N4 Ceramics"

这个小企业创新研究项目将制定一个方案，优化聚（乙炔基）硅氮烷（PESZ）的合成，重点是提高效率和降低生产成本;将扩大PESZ聚合物的生产规模，达到中试规模的批量规模;将优化PESZ加工，用于部件制造;将制造“真实的世界”部件，如推力偏转器和柴油发动机微粒过滤器;并将获得“真实的世界”的机械和性能测试数据。 在实现这些目标的过程中，将寻求商业机会。这种方法有可能制造出超大型陶瓷基复合材料（CMC）结构，而这种结构的制造方式与目前制造的大型聚合物基飞机结构和船体结构的制造方式完全相同，其商业应用将是制造可用于飞机工业的超大型CMC结构。

This Small Business Innovation Research (SBIR) project will develop a program that will optimize poly (ethynyl) silazanes (PESZ) synthesis with an emphasis on improved efficiency and low production costs; will scale-up the production of PESZ polymers to pilot scale batch sizes; will optimize PESZ processing for component fabrication; will fabricate "real world" components, such as thrust deflectors and diesel engine particulate filters; and will obtain "real world" mechanical and performance testing data. Through the course of achieving these objectives, commercial opportunities will be pursued. This approach potentially permits the fabrication of extremely large ceramic matrix composites (CMCs) structures never before possible in much the same manner as large polymer matrix aircraft structures and boat hulls are currently manufactured.The commercial application will be the fabrication of extremely large CMC structures that can be used in the aircraft industry.
