This Small Business Innovation Research (SBIR) Phase II project will develop materials and processes that enable any composite resin system to be produced Out Of Autoclave (OOA) with excellent inner and outer surfaces. To ensure high quality and reliability, aerospace composites are processed inside autoclaves that combine heat and pressure. The capital and labor costs and manufacturing times associated with autoclave processing are significant but necessary to ensure composite quality. Achieving high-complexity geometries poses additional hurdles. Current methods used in these cases include a small selection of OOA pre-impregnated parts, the use of thermoplastic bladders, or the bonding of autoclaved components. A large opportunity exists for OOA technology to reduce material and labor costs while also enabling one piece, seamless composite structures with extremely complex internal & external geometries, allowing manufacturing of parts which were previously unachievable. The Phase II project will further the development of a self-pressurizing technology that allows OOA processing of any resin system without a loss in quality. The Phase II will expand the operating temperature and pressure window, improve forming processes, and characterize performance on commercially relevant pre-impregnated systems. Phase II results will yield a mature forming process and several tooling grades with verified performance.The broader impact/commercial potential of this project is the realization of a manufacturing technology that will enable the composites industry to form more complex geometries and allow greater competition throughout the industry. Society will see benefits through the broader use of fuel-efficient composites in air and land based vehicles and smaller carbon waste streams. 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. The proposed technology will impact new aircraft as well as the design and manufacture of other vehicles. Technologically, this project will lead to a better understanding of self-pressurizing materials and their potential applications, as well as advance domestic manufacturing capabilities. Finally, undergraduates at the University of Arizona will have an opportunity to work on the project in conjunction with industrial scientists and engineers.

这项小型企业创新研究（SBIR）第二阶段项目将开发材料和过程，使任何复合树脂系统都能从高压釜（OOA）中生产出具有出色的内部和外表面。为了确保高质量和可靠性，在混合热量和压力的高压灭菌中处理航空复合材料。 与高压釜处理相关的资本和人工成本以及制造时间是重要的，但对于确保综合质量是必不可少的。 实现高复杂的几何形状会带来额外的障碍。 在这些情况下使用的当前方法包括一小部分OOA预先浸渍的部分，使用热塑性膀胱或高压灭菌组件的键合。 OOA技术存在巨大的机会，可以降低材料和人工成本，同时还可以实现具有非常复杂的内部和外部几何形状的无缝复合结构，从而允许制造以前无法实现的零件。 第二阶段项目将进一步开发一种自动化技术，该技术允许对任何树脂系统进行OOA处理而不会造成质量损失。第二阶段将扩大工作温度和压力窗口，改善形成过程，并表征商业相关的预先浸渍系统的性能。第二阶段的结果将产生一个成熟的成型过程和具有验证性能的几个工具等级。该项目的更广泛的影响/商业潜力是实现制造技术，该技术将使复合材料行业能够形成更复杂的几何形状，并在整个行业中更大。 社会将通过在空气和陆基车辆和较小的碳废物流中更广泛使用燃油效率的复合材料来看到好处。 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。 波音公司的787和空中客车公司的A350是两架这样的飞机，这些飞机示出了将复合含量提高到50％以上的推动力。 拟议的技术将影响新飞机以及其他车辆的设计和制造。 从技术上讲，该项目将使人们更好地了解自我压力的材料及其潜在应用，并提高国内制造能力。 最后，亚利桑那大学的大学生将有机会与工业科学家和工程师一起研究该项目。
