This Major Research Instrumentation (MRI) award provides funds for the purchase of a large scale, Solidica ultrasonic consolidation system. This equipment will be used to support research on the fundamentals of ultrasonic consolidation traversing lengths scales from atomistic, molecular dynamic modeling, to hierarchical design/optimization procedures. These include examination of atomic species migration during ultrasonic consolidation, fabrication of multilayer smart materials incorporating ceramic fibers, polymers and metallic layers, large scale ultrasonic curing of fiber reinforced thermosetting polymers, benign environmental treatment of textile fiber surfaces and low temperature fabrication of intermetallic matrix composites. It will also be used to support the undergraduate interdisciplinary senior design program.This equipment will contribute to developing a knowledge base in ultrasonic consolidation which has application in biomedical devices, aeroengines and air frames. Specifically the knowledge gained will allow incorporation of sensors and direct communication links in orthopedic devices, achievement of real time control variable configuration wing components and direct manufacture of aeroengine components incorporating both cooling air passages and thermal/damage sensors and actuators.

该主要研究仪器（MRI）奖为购买大型Solidica超声巩固系统提供资金。该设备将用于支持从原子、分子动力学建模到分层设计/优化程序的超声固结穿越长度范围的基础研究。其中包括超声固结过程中原子迁移的检测，结合陶瓷纤维、聚合物和金属层的多层智能材料的制造，纤维增强热固性聚合物的大规模超声固化，纺织纤维表面的良性环境处理以及金属间基复合材料的低温制造。它还将用于支持本科跨学科高级设计课程。该设备将有助于开发超声波加固知识库，该知识库已应用于生物医学设备，航空发动机和飞机框架。具体来说，所获得的知识将允许在矫形设备中集成传感器和直接通信链路，实现实时控制可变配置机翼部件，以及直接制造包含冷却空气通道和热/损伤传感器和执行器的航空发动机部件。
