该MRI项目奖为安柏瑞德航空大学（ERAU）提供了获得最先进材料测试仪器的机会。这些设备将用于科学/工程研究、课程实验活动、加强学生培训和向来访的学生及其家人展示科学/工程。将获得最先进的伺服液压材料测试系统（疲劳额定），其容量为55kip，能够进行广泛的机械测试。该仪器将取代严重过时的机械测试能力（目前每学期约有100名本科生使用），这些能力无法执行表征现代材料行为所需的许多任务。目前的研究和开发领域注定要利用新的仪器包括细胞固体和复合材料。该奖项还为参观者（例如，ERAU暑期学院的学生）提供了最先进的演示能力，旨在帮助解释材料对社会的重要性，以及如何根据测量的性能选择材料。接触新的材料，结构和相关的测量仪器可以提高学习经验，并在早期促进科学/工程。目前，关于新型蜂窝固体的设计、制造和性能的最新知识仅限于相对较少的蜂窝结构和基础材料。现有的性能数据很少，工业规模尚未实现。提出的研究将有助于如何设计和制造新型细胞固体的知识。结合性能评估（可以使用拟议的测试系统），这将通过建立基准性能标准和未来工业规模扩大的手段来实现进一步的进展。所提出的测试系统也将在复合材料的研究中发挥关键作用。涉及冲击复合材料的抗压强度和剩余疲劳寿命的研究将利用所提出的仪器。计划对复合材料研究人员和航空航天界具有重要意义的高质量结果。该奖项的研究部分围绕着发现和理解如何设计、制造和测试细胞固体和复合材料。由于其特殊的重量特性和潜在的多功能能力，这些材料使社会能够以更少的资源做更多的事情，以实现最佳的资源利用。他们非常有效地利用原材料，从而节约了材料资源和能源。使用所提出的仪器可以实现精确的性能测量。为了使对材料相关研究感兴趣的学生和教师受益，ERAU的实验和研究能力得到了加强。一个由4个学系7名教师组成的多学科研究团队。新的仪器将使这些部门能够创造设备齐全的学习环境，将研究与教育结合起来。由于欧洲经委会主要是一个教学机构，这些仪器也将用于研究生和本科生课程。这使学生接触到广泛用于研究材料和结构特性的实验技术和设备。参观者（例如，ERAU暑期学院学生）的演示有助于解释材料对社会的重要性，以及如何根据测量的性能选择材料。通过向年轻人展示最先进的材料和设备，令人兴奋的创新开始在年轻时孕育。

OIA-0521183Abstract This MRI Program award provides Embry-Riddle Aeronautical University (ERAU) with the opportunity to acquire state-of-the-art materials testing instrumentation. The equipment will be used for scientific/engineering research, course lab activity, enhanced student training and exposure of science/engineering to visiting students and their families. A state-of-the-art servohydraulic materials test system (fatigue rated) with 55 kip capacity capable of performing a wide range of mechanical tests will be acquired. This instrumentation will replace severely outdated mechanical testing capabilities (currently utilized by approximately 100 undergraduate students per semester) that are incapable of performing many of the tasks needed to characterize the behavior of modern materials. Current areas of research and development destined to utilize the new instrumentation include cellular solids and composites. The award also provides ERAU with state-of-the-art capabilities for visitor (e.g., ERAU Summer Academy students) demonstrations esigned to help explain the importance of materials to society and how materials are selected based upon measured properties. Exposure to new materials, structures and the associated measurement apparatus enhances the learning experience and promotes science/engineering at an early age. The current state-of-art-knowledge regarding the design, fabrication and performance of new cellular solids is limited to relatively few cellular architectures and base materials. Little properties data exists and industrial scale-up has not yet been achieved. The proposed research would contribute to the knowledge of how to design and fabricate new types of cellular solids. Combined with properties evaluation (made possible using the proposed test system) this will enable further progress by establishing baseline performance standards and the means for future industrial scale-up. The proposed test system would also play a critical role in composite materials research. Investigations involving the compressive strength and residual fatigue life of impacted composites would utilize the proposed instrumentation. Quality results of great importance to composites researchers and the aerospace community are planned. The research portion of this award revolves around discovering and understanding how to design, fabricate and test cellular solids and composites. Owing to their exceptional weight specific properties and potential multifunctional capabilities, these materials allow society to do more with less for optimal resource use. They make extremely efficient use of raw materials such that material resources and energy are conserved. Accurate properties measurements are achieved using the proposed instrumentation. Enhanced are the experimental and research capabilities at ERAU for the benefit of students and faculty interested in materials related research. A multi-disciplinary research team with 7 faculty members from 4 academic departments is involved. The new instrumentation will enable these departments to create well-equipped learning environments that integrate research with education. Since ERAU is primarily a teaching institution, the instrumentation will also be utilized for graduate and undergraduate courses. This exposes students to experimental techniques and equipment widely used to study the properties of materials and structures. Visitor (e.g., ERAU Summer Academy students) demonstrations help explain the importance of materials to society and how materials are selected based upon measured performance. By showing young adults state-of-the-art materials and apparatus, exciting innovations begin to nurture at an early age.
