Thermal Spraying of Silicon Carbide Coatings for Low Cost Ceramic Composite Manufacturing

目前用于制造先进复合材料的方法导致交货时间长和部件成本高，并限制了复合材料在商业应用中的广泛使用。本文介绍了一种在露天条件下用热喷涂技术制备碳化硅的新工艺。SBIR第一阶段计划的目标是研究用于低成本制造复合结构的碳化硅成型技术。SiC技术将作为（1）纤维增强复合材料的表面涂层和（2）将各种高强度纤维结合到复合材料结构中的基体材料进行评估。如果成功，这项技术有可能在复合材料制造成本和时间上减少一个数量级。该提案是一项为期6个月的工作，重点是使用小型原型进行实验性评估，以评估技术可行性。第一阶段活动的总费用为61，500.00美元

Current methods used in the manufacturing of advanced composite materials contribute to long delivery times and high component costs, and limits widespread usage of composites in commercial applications. A new technology has been developed for forming silicon carbide using thermal spray techniques in open air. The goal of this SBIR Phase I proposal is to investigate this silicon carbide forming technology for low cost fabrication of composite structures. The sic technology will be evaluated as (1) a surface coating for fiber reinforced composites and (2) as a matrix material for incorporating various high strength fibers into composite structures. If successful, this technology has the potential for an order of magnitude reduction in composite manufacturing cost and time. This proposal is a 6 month effort which focuses on experimental evaluating using small prototypes to assess technical feasibility. The total cost of the Phase I activity is $61,500.00
