PI：Amano，Ryoichi Proposal编号：1236312机构：威斯康星大学密尔沃基分校标题：仿生先进复合聚合物风力机叶片风力涡轮机零排放，风能是可再生和免费的；然而，风能转换系统产生和获得的电量不稳定，相对昂贵，由于风源的变化和尚未解决的能量储存问题，很难整合到传统电力系统中。此外，绝大多数可用风的速度太慢，这使得收集风电变得更加困难，而易于收集的风能主要局限于偏远地区，这使得配电困难。为了实现在中低风地区提高功率的经济可行性，必须在涡轮机设计方面取得重大进展，以增加电力收集。该项目研究了一种具有创新的自愈方法的叶片破损自修复系统。拟议的项目建立在皮耶？S对一种创新的高能效风力发电机组叶片的实验研究的基础上，该试验研究旨在改善风力发电机组的性能，降低噪声辐射，并实施一种自我修复机制，以纠正风力发电机组运行期间的故障。这项任务将通过引入基于聚合物的自愈概念来修复风力涡轮机叶片来实现。这项拟议的研究将在威斯康星大学密尔沃基分校(UWM)的能源中心进行。与S中心的合作伙伴公司一起，PI将为风力涡轮机诊断和预测研究创建一个试验台和实验数据集，供该领域的其他研究人员使用。复合材料叶片是使用费力的玻璃纤维增强手工铺设技术制造的。纤维增强复合材料的使用增长迅速，这类复合材料经常用于航空航天和其他应用；然而，人们仍然担心冲击载荷后复合材料的结构完整性，因为它们容易在结构内部形成裂缝或分层。随着风力机叶片自修复技术的成功，风力机叶片上的任何裂纹部件都可以在运行过程中修复，而不会关闭任何系统。因此，这项研究将揭示现有的风力发电机故障预防方法，并为适应21世纪风能时代的涡轮叶片新材料提供新的概念和方法。该项目将与美国能源部资助的与密尔沃基地区技术学院联合开展的东南威斯康星州风能教育合作计划目前正在开发的课程完全整合。该课程将补充威斯康星大学现有的风能课程，覆盖本科生和研究生，并增加劳动力中工程师的供应。此外，该协会将与少数族裔和女性学生合作，通过威斯康星大学的“儿童/青少年学院”暑期计划，为大学预科学生提供研究机会。研究结果将在由国际和平协会及其合作者在瑞典组织的国际研讨会上传播，与会者将被邀请，包括年轻教员、代表不足的群体和妇女以及研究生。

PI: Amano, RyoichiProposal Number: 1236312Institution: University of Wisconsin-MilwaukeeTitle: Biomimetic Advanced Composite Polymer for Wind Turbine BladeWind turbines are emissions-free and wind is renewable and cost-free; however, the amount of electricity generated and obtained by wind energy conversion systems is unsteady, relatively expensive, and difficult to integrate into traditional electricity systems because of the variation in wind source and unresolved energy storage issues. Furthermore, the vast majority of available wind is too slow, which makes collecting wind power more difficult, and the easy-to-collect wind energy is primarily confined to remote locations, which makes electricity distribution difficult. In order to achieve economic feasibility in enhancing the power in medium- to low-wind areas, significant advances in turbine design are necessary for increased power collection. This project investigates a blade breakage self-repair system with an innovative self-healing approach. The proposed project builds upon the PI?s experimental research of an innovative, power-efficient wind turbine blade to improve wind turbine performance, reduce noise radiation, and to implement a self-repair mechanism to correct wind turbine failure during operation. The task will be achieved by introducing a polymer-based self-healing concept to repair the wind turbine blades. The proposed research will be conducted in the Energy Center at the University of Wisconsin-Milwaukee (UWM). Along with the Center?s partner companies, the PI will create a test bed and experimental datasets for wind turbine diagnosis and prognosis research that can be used by other researchers in this field.The composite blades are manufactured using a laborious, hand lay-up technique with glass fiber reinforcements. The use of fiber-reinforced composite materials has grown rapidly and such composites are often used in aerospace and other applications; however, concerns remain about the structural integrity of composite materials following impact loading, as they are susceptible to cracks or delaminations that form deep within the structure. With the success of the self-healing technology for wind turbine blades, any cracked parts in wind turbine blades can be healed during operation without any system shutting down. Therefore, this research will shed light on the existing wind turbine failure prevention methods, and provide new concepts and approaches for new materials of turbine blades suitable for the 21st century wind energy era.This project will be fully integrated with the curriculum currently being developed by the Southeast Wisconsin Wind Energy Educational Collaborative program, a joint project with Milwaukee Area Technical College that is funded by the U.S. Department of Energy. This curriculum will complement existing wind energy courses at UWM, reach undergraduate and graduate students, and increase the supply of engineers in the workforce. In addition, the PI will work with minority and female students through the UWM "College for Kids/Teens" summer program to provide research opportunities to pre-college students. The research findings will be disseminated at an international workshop organized by the PI and his collaborators in Sweden, where participants, including young faculty, underrepresented groups and women, and graduate students will be invited.
