This I-Corps project seeks to identify the commercial potential of an automated composite manufacturing technology. The broader impact/commercial potential of this I-Corps project is that it enables new design options for composites -- impacting a wide range of industries. This team's technology is an automated method of forming composites that seeks to improve capabilities in the area of composite manufacturing. The technology allows designers to create new structures that are not currently synthesized or manufactured. Aircraft and automobile industries are typical sectors where composites are used to reduce weight. Through this project's technology, composite designers will be able to realize greater weight savings than they have using traditionally designed and manufactured composites. These weight savings will allow designers to meet fuel efficiency standards, increase payload capacity, and extend the range of vehicles or airplanes.Composites formed using traditional automated processes are constrained to 2D laminate structures using unidirectional tapes (narrow, woven fabric materials). Composites formed this way are vulnerable to impact damage and severely limit the options available to the designer. This project's technology permits the local manipulation of fabric geometry in a composite, which allows designers to optimize the strength and stiffness of the composite structure. Additionally, this technology allows interlacing of adjacent layers in the composite, which enhances the impact resistance of the composite. Participation in I-Corps will allow the proposed technology to be evaluated for commercial merit and enable the development of a commercialization strategy.

这个I-Corps项目旨在确定自动复合制造技术的商业潜力。这个I-Corps项目的更广泛的影响/商业潜力是，它可以为复合材料提供新的设计选项 - 影响广泛的行业。 该团队的技术是形成复合材料的自动化方法，旨在提高复合制造领域的能力。 该技术使设计人员可以创建当前未合成或制造的新结构。飞机和汽车行业是使用复合材料来减轻体重的典型部门。通过该项目的技术，复合设计师将能够比使用传统设计和制造的复合材料实现更大的体重节省。 这些节省的重量将使设计人员能够达到燃油效率标准，增加有效载荷能力，并扩展使用传统自动化工艺形成的车辆或飞机的范围。​​使用单向磁带（窄，编织的织物材料）将传统的自动化过程限制在2D层压层结构上。 以这种方式形成的复合材料容易受到影响损害，并严重限制了设计师可用的选项。 该项目的技术允许在复合材料中局部对织物几何形状进行操纵，从而使设计人员可以优化复合结构的强度和刚度。 此外，该技术允许复合材料中相邻层的交织，从而增强了复合材料的影响力。 参与I-Corps将允许对拟议的技术进行评估以获得商业功绩，并能够制定商业化策略。
