This Small Business Innovation Research Phase I project will develop new low cost, high performance tooling materials for composite manufacturing. The use of advanced fiber reinforced composites in aircraft has become a necessity to achieve higher performance and greater fuel efficiencies. Boeing?s 787 and Airbus?s A350 are two such aircraft that exemplify the push to increase composite content above 50% by weight. There is a similar push in other transportation vehicles as well. A large opportunity exists for RTM process technology to reduce costs and streamline composite manufacturing operations. Phase I results will have a large impact on the composites industry through cost reduction and manufacturing efficiency gains. It will allow a broader manufacturing base to produce composite parts. Society will see benefits through the broader use of fuel efficient composites in air and land based vehicles. The technology developed can generate $10-$20M in annual revenue within 5 years of the program end. This effort will also foster collaboration between Advanced Ceramics Manufacturing and large aerospace manufacturers. Undergraduates at the University of Arizona and local high school students will have an opportunity to work on the project. Results of this research will be disseminated in multidisciplinary conferences and journals.The intellectual merit of this project is developing low cost materials and manufacturing processes that enable composite materials to be produced in high rate resin transfer molding (RTM). Compared to autoclave based processes, RTM offers several key advantages. This includes: high internal and external geometric complexity, less waste, lower volatile emissions, higher production rates, and excellent surface finish. However, the injection of high pressure ? high temperature resin presents a tooling challenge. Tooling can be a limiting factor for utilizing RTM as the preferred manufacturing route. A large opportunity exists for new tooling technology that can withstand RTM conditions and be easily extracted from the composite after the cure cycle. A soluble RTM capable material will allow RTM applications to grow and reduce the cost of composite manufacturing. The project will develop a new soluble binder-aggregate system that can withstand all RTM process conditions. The results of the Phase I will demonstrate a low cost RTM compatible tooling system that can be formed at high rate and used in high rate composite RTM cycles.

这个小型企业创新研究阶段I项目将开发新的低成本，高性能工具材料，用于复合制造。在飞机中使用先进的纤维增强复合材料已成为实现更高性能和提高燃油效率的必要性。 波音787和空中客车A350是两架这样的飞机，例如将复合含量提高到50％以上的推动力。 其他运输车也有类似的推动力。 RTM流程技术存在很大的机会，以降低成本和简化复合制造运营。 第一阶段的结果将通过降低成本和制造效率提高对复合材料行业产生重大影响。它将允许更广泛的制造基础产生复合零件。 社会将通过在空气和陆基车辆中更广泛使用燃油效率的复合材料来看到好处。 开发的技术可以在该计划结束后的5年内产生10至2000万美元的年收入。这项工作还将促进高级陶瓷制造和大型航空航天制造商之间的合作。 亚利桑那大学和当地高中学生的大学生将有机会从事该项目。 这项研究的结果将在多学科的会议和期刊中传播。该项目的智力优点正在开发低成本材料和制造过程，使得能够以高速树脂传输成型（RTM）生产复合材料。与基于高压灭菌的流程相比，RTM提供了几个关键优势。 这包括：高内部和外部几何复杂性，较少的废物，较低的挥发性排放，较高的生产率和出色的表面饰面。 但是，注射高压？高温树脂提出了工具挑战。 工具可能是利用RTM作为首选制造路线的限制因素。对于可以承受RTM条件并在固化周期后轻松从复合材料中提取的新工具技术的机会很大。 可溶性RTM的材料将允许RTM应用程序增长并降低复合制造的成本。该项目将开发一个新的可溶性粘合剂聚集系统，该系统可以承受所有RTM过程条件。 阶段I的结果将证明低成本的RTM兼容工具系统，该系统可以高速速率形成并用于高速复合RTM循环。
