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，组件成本高，并且限制了复合材料在商业应用中的广泛使用。开发了一种利用露天热喷涂技术形成碳化硅的新技术。SBIR第一阶段提案的目标是研究这种低成本制造复合材料结构的碳化硅成形技术。sic技术将被评价为(1)纤维增强复合材料的表面涂层和(2)将各种高强度纤维纳入复合材料结构的基体材料。如果成功，该技术有可能将复合材料的制造成本和时间降低一个数量级。该提案是一个为期6个月的努力，重点是使用小型原型进行实验评估，以评估技术可行性。第一阶段活动的总费用为61 500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
