项目负责人：Amano， ryoichi提案编号：1236312机构：威斯康星大学密尔沃基分校标题：用于风力涡轮机叶片的仿生先进复合聚合物风力涡轮机是零排放的，风能是可再生的，并且是免费的；然而，风能转换系统产生和获得的电量不稳定，相对昂贵，并且由于风源的变化和未解决的储能问题难以整合到传统的电力系统中。此外，绝大多数可用的风都太慢，这使得收集风能变得更加困难，而且容易收集的风能主要局限于偏远地区，这使得电力分配变得困难。为了实现在中、低风区提高功率的经济可行性，需要在涡轮机设计上取得重大进展，以增加功率收集。本项目研究了一种具有创新的自修复方法的叶片断裂自修复系统。建议的项目建立在PI的基础上？S试验研究一种创新的、节能的风力机叶片，以提高风力机的性能，降低噪声辐射，并实现自修复机制，纠正风力机在运行过程中的故障。该任务将通过引入基于聚合物的自修复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。和中心一起吗？作为合作伙伴，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。复合叶片是用玻璃纤维增强材料手工制作的。纤维增强复合材料的使用迅速增长，这种复合材料经常用于航空航天和其他应用；然而，人们仍然担心复合材料在冲击载荷后的结构完整性，因为它们很容易在结构深处形成裂缝或分层。随着风电叶片自修复技术的成功，风电叶片中任何有裂纹的部件都可以在不停机的情况下在运行中修复。因此，本研究将为现有的风力机故障预防方法提供新的思路和途径，为适合21世纪风能时代的风力机叶片新材料提供新的思路和途径。该项目将完全整合威斯康星东南风能教育合作项目目前正在开发的课程，该项目是由美国能源部资助的密尔沃基地区技术学院联合项目。该课程将补充UWM现有的风能课程，面向本科生和研究生，并增加劳动力中工程师的供应。此外，PI将通过威斯康星大学的“儿童/青少年学院”暑期项目与少数民族和女学生合作，为大学预科学生提供研究机会。研究结果将在PI及其合作者在瑞典组织的一次国际讲习班上传播，将邀请参加者，包括年轻教员、代表性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.
