项目摘要

This Grant Opportunity for Academic Liaison with Industry (GOALI) project will research a new method for the manufacture of plastics and fiber reinforced composite materials, which are critical elements in structures like aircraft, automobiles and wind turbine blades, where light weight and high strength are required. Current methods for manufacturing these materials are costly and energy intensive, due to the high temperatures and long times required for processing. Drawing inspiration from how living system develop, this multidisciplinary research project will result in new plastic materials that require only small initial energy input to rapidly trigger the entire manufacturing process and dramatically reduce environmental impact. This new, more efficient method has significant potential to improve U.S. economic competitiveness in the critical area of composites manufacturing. The energy efficient concepts under development also provide an ideal platform to motivate and educate the next generation of students, postdoctoral researchers, entrepreneurs, industry and the general public on the importance of sustainable manufacturing. A new manufacturing method for thermosetting polymers, coatings and composites will be developed based on an autocatalytic (self-propagating) polymerization reaction occurring in a system undergoing reaction and diffusion of its components. The system uses the exothermic release of energy to provide a positive feedback to the reaction. In turn, this stimulates further exothermic energy release and a self-propagating reaction front that rapidly moves through the material; a process called frontal polymerization. Once triggered, the reaction progresses with zero energy input. The self-sustained propagation of a reaction wave through the material gives rise to entirely new ways of rapidly manufacturing high performance polymers and composites, without the use of conventional autoclaves or ovens. The planned research will lead to scientific advances in the organic chemistry of self-propagating reactions, machine learning driven design and synthesis of new monomers for frontal polymerization, multiscale characterization and modeling of front instabilities, and control of frontal polymerization for manufacturing. The research objectives are designed to improve fundamental understanding of frontal polymerization and to apply this knowledge to the rapid out-of-autoclave production of thermosetting coatings, fiber-reinforced composites and 3D printed architecturally complex, reinforced polymers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个学术与工业联络资助机会（GOALI）项目将研究一种制造塑料和纤维增强复合材料的新方法，这些材料是飞机、汽车和风力涡轮机叶片等结构的关键元件，需要轻质和高强度。目前制造这些材料的方法是昂贵和能源密集型的，因为加工需要高温和长时间。从生命系统的发展中汲取灵感，这个多学科的研究项目将产生新的塑料材料，只需要很小的初始能量输入，就能迅速触发整个制造过程，并大大减少对环境的影响。这种新的、更有效的方法具有显著的潜力，可以提高美国在复合材料制造关键领域的经济竞争力。正在开发的节能概念也提供了一个理想的平台，以激励和教育下一代学生、博士后研究人员、企业家、工业界和公众可持续制造的重要性。一种新的热固性聚合物、涂料和复合材料的制造方法将基于发生在其组分的反应和扩散体系中的自催化（自传播）聚合反应。该系统利用放热释放的能量为反应提供正反馈。反过来，这刺激了进一步的放热能量释放和快速穿过材料的自传播反应锋；这个过程叫做正面聚合。一旦被触发，反应就会在零能量输入的情况下进行。反应波在材料中的自我持续传播，产生了一种全新的快速制造高性能聚合物和复合材料的方法，而无需使用传统的高压灭菌器或烤箱。计划中的研究将在自传播反应的有机化学、机器学习驱动的正面聚合新单体的设计和合成、正面不稳定性的多尺度表征和建模以及制造中的正面聚合控制方面取得科学进展。研究目标旨在提高对正面聚合的基本理解，并将这些知识应用于热固性涂层、纤维增强复合材料和3D打印结构复杂的增强聚合物的快速非高压釜生产。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
