The research objective of this grant is to develop a new class of high damping structures having a shape memory metal alloy composite casing over a carbon fiber reinforced polymeric (FRP) composite tube. It is expected that the traditional FRP core will provide the high stiffness while the damping capacity accomplished by the shape memory alloy casing. The research will be conducted in three key segments: (1) developing the fabrication technology (spray forming) for building shape memory alloy casings on the FRP cores, (2) characterizing the stiffness, strength and damping capabilities of the new structures, and (3) integrating the design, manufacture, and field testing of prototype automotive half -shafts. The fabrication technology to be developed as part of this project will introduce a new way of making multi-material, multi-functional structures that cannot be conveniently fabricated by other manufacturing methods. These novel high damping structures would find use in challenging, vibration prone applications in the automotive, aerospace, and cutting tool industries. The project includes collaboration among university researchers, REU students, and industrial engineers. The automotive and composite manufacturing industries have pledged support for the project and will be collaborative partners providing composite manufacturing and prototype field-testing. Learning modules will be developed from the research and included in the undergraduate and graduate curriculums. A goal is to stimulate undergraduate and graduate students to pursue advanced educational degrees. The integrated research and educational objectives will benefit the participating industries and will provide their engineers with unique training for further advancing the state-of-art.

这笔赠款的研究目标是开发一种新型的高阻尼结构，在碳纤维增强聚合物(FRP)复合管上具有形状记忆金属合金复合外壳。预计传统的玻璃钢芯材将提供较高的刚度，而减振能力则由形状记忆合金外壳来实现。研究将分三个关键部分进行：(1)开发在玻璃钢芯材上制造形状记忆合金外壳的制造技术(喷射成形)；(2)表征新结构的刚度、强度和减振能力；(3)整合汽车半轴原型的设计、制造和现场试验。作为该项目的一部分而开发的制造技术将引入一种制造多材料、多功能结构的新方法，这些结构是其他制造方法无法方便地制造的。这些新颖的高阻尼结构将在汽车、航空航天和刀具行业中具有挑战性、易振动的应用中得到应用。该项目包括大学研究人员、REU学生和工业工程师之间的合作。汽车和复合材料制造业已承诺支持该项目，并将成为提供复合材料制造和原型现场测试的合作伙伴。将根据研究开发学习模块，并将其纳入本科生和研究生课程。一个目标是刺激本科生和研究生攻读高等教育学位。综合研究和教育目标将使参与的行业受益，并将为他们的工程师提供独特的培训，以进一步推动最先进的技术。
