This Small Business Innovation Research (SBIR) Phase I project will develop an innovative new ultraviolet (UV) curable pre-ceramic polymer chemistry for the fabrication of high yield and low cost silicon oxycarbide (SOC) fibers for diesel particulate filters and other applications. Silicon carbide (SiC), silicon nitride (Si3N4), and silicon nitride/silicon carbide (Si3N4/SiC) ceramics have been fabricated from UV photocurable pre-ceramic polymers to SiC and Si3N4/SiC with higher than 85 percent ceramic yield. Preliminary experiments have demonstrated that SOC fibers can also be fabricated from high-viscosity, photocurable thermoplastic pre-ceramic polymers. The poly(ethynyl)siloxane pre-ceramic polymers also have potential as a binder or matrix phase in SOC/SOC composites. Phase I will optimize fiber production techniques.Potential commercial applications are expected in particulate diesel filters for manufacturers in the automotive and truck markets.

该小型企业创新研究（SBIR）第一阶段项目将开发一种创新的新型紫外线（UV）可固化陶瓷前体聚合物化学，用于制造高产量和低成本的碳氧化硅（SOC）纤维，用于柴油机颗粒过滤器和其他应用。 采用紫外光固化预聚体制备了碳化硅（SiC）、氮化硅（Si 3 N4）和氮化硅/碳化硅（Si 3 N4/SiC）陶瓷，陶瓷产率大于85%。初步实验表明，SOC纤维也可以由高粘度、可光固化的热塑性预陶瓷聚合物制成。 聚（乙炔基）硅氧烷预陶瓷聚合物也具有作为SOC/SOC复合材料中的粘合剂或基质相的潜力。 第一阶段将优化纤维生产技术。预计在汽车和卡车市场的颗粒柴油过滤器制造商的潜在商业应用。
