The broader impact/commercial potential of this I-Corps project is the development of carbon fiber-reinforced, polymer recycling technology in the US marketplace. The lack of efficient recycling routes is a primary hurdle to the use of carbon fiber-reinforced polymers in automotive and other large-scale manufacturing applications. Such recycled fibers represent a new class of feedstock for composite manufacturers as their surface chemistry is unaffected by the recycling process and their native length and architecture is preserved, maximizing their physical properties and maintaining their performance. This technology may accelerate the acceptance of carbon fiber composites as a ‘green’ material by upcycling composite waste from the aerospace sector for use in automotive, sporting goods, and wind blade industries. This I-Corps project is based on the development of a novel technology to remanufacture carbon fiber-reinforced polymer composites from post-consumer waste into carbon fiber sheets and resin raw materials recovered through a recycling process. The proposed technology incorporates a homogeneous chemical recycling reaction which utilizes oxygen as the terminal oxidant to oxidize key carbon-nitrogen bonds formed during the thermoset curing reaction of the polymer. As a result, woven carbon fiber sheets are recovered, still in their native architecture, with minimal damage to their surface chemistries. These recycled fiber weaves retain their physical properties and may enable myriad remanufacturing possibilities.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.

该I-Corps项目的更广泛的影响/商业潜力是在美国市场上开发了碳纤维增强的聚合物回收技术。缺乏有效的回收路线是在汽车和其他大型制造应用中使用碳纤维增强聚合物的主要障碍。这种回收纤维代表了一类新的组合制造商原料，因为其表面化学不受回收过程的影响，并且保留了它们的天然长度和体系结构，从而最大程度地提高了其物理性能并保持其性能。通过将航空航天部门的复合材料废物升级用于汽车，体育用品和风叶片工业，该技术可能会加速接受碳纤维成分作为“绿色”材料。这个I-Corps项目基于开发一种新技术，以从后消费者废物中重新制造的碳纤维增强聚合物组合物为碳纤维板和通过回收过程回收的树脂原材料。提出的技术结合了均匀的化学回收反应，该反应利用氧作为在聚合物的热固性固化反应过程中形成的氧化物与氧化物关键碳氮键。结果，编织的碳纤维板被回收，仍处于本地建筑中，对其表面化学分配的损害最小。这些可回收​​的纤维编织保留了其物理性能，并可能使无数的再制造可能性。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估诚实地表示支持。
