The research objective of this award is to develop fundamental dynamic models of web behavior for composite webs that are manufactured and processed in roll-to-roll (RTR) manufacturing systems. Composite webs are formed from dissimilar individual flexible material layers or through application of a thick gel material onto a base layer. In addition to developing models, a related core objective is to design the configuration (selection of location of driven rollers, web guides, and sensing systems) of the RTR systems and associated coordinated control strategies for RTR machine elements that would enable manufacture of quality composite webs with fewer defects. The research approach is to develop realistic models of web dynamics using first principles that can predict observed behavior during the formation of the composite web and its subsequent transport through processing machinery. The models will be analyzed to develop methods to efficiently configure primitive elements of RTR systems. The project will also develop new model-based control strategies for primitive elements to control key process variables such as web tension, transport velocity and lateral position. Deliverables include composite web models, modeling and analysis tools for RTR systems, demonstration and validation via software and hardware, documentation of research results, engineering student education, and training of practicing engineers in modern methods and technologies. If successful, the results of this research will provide methods to manufacture composite webs with improved product quality, less wastage, and reduced cost. The focus will be on composite flooring and ceiling products but the methods and tools developed will be general enough for use in manufacture of a wide variety of other existing consumer web products such as paper tissues, plastic film, hygiene products, etc. The potential for application of the research to development of new consumer products such as flexible electronics using RTR manufacturing is also substantial. Graduate and undergraduate engineering students will benefit through interactions with practicing engineers and involvement in applied research activities at the industrial site. International collaboration will enhance research progress and will provide a mechanism for engineering students to interact with foreign counterparts.

该奖项的研究目标是为在卷对卷（RTR）制造系统中制造和加工的复合材料腹板开发腹板行为的基本动态模型。复合网由不同的单个柔性材料层或通过将厚凝胶材料施加到基层上形成。除了开发模型之外，一个相关的核心目标是设计RTR系统的配置（选择从动辊、幅材引导件和传感系统的位置）以及用于RTR机器元件的相关协调控制策略，这将使得能够制造具有较少缺陷的高质量复合幅材。研究方法是开发现实的网络动态模型，使用第一原理，可以预测观察到的行为，在复合网络的形成和随后的运输通过加工机械。模型将进行分析，以开发方法，有效地配置RTR系统的原始元素。该项目还将为原始元件开发新的基于模型的控制策略，以控制关键工艺变量，如纸幅张力、输送速度和横向位置。可提供的内容包括复合网络模型、RTR系统的建模和分析工具、通过软件和硬件进行的演示和验证、研究结果文档、工程学生教育以及现代方法和技术的实践工程师培训。如果成功的话，这项研究的结果将提供方法来制造复合材料网络，提高产品质量，减少浪费，降低成本。重点将放在复合地板和天花板产品，但开发的方法和工具将是一般性的，足以用于制造各种其他现有的消费网络产品，如纸巾，塑料薄膜，卫生产品等的潜力，应用研究开发新的消费产品，如灵活的电子产品，使用RTR制造也是巨大的。研究生和本科工程专业的学生将通过与实践工程师的互动和参与工业现场的应用研究活动而受益。国际合作将促进研究进展，并将为工程专业学生提供一个与外国同行互动的机制。
