项目摘要
This Major Research Instrumentation (MRI) award supports the acquisition of a state-of-the-art Drop Tower Impact Tester at Tuskegee University (TU). This instrument will enable the development of stronger and durable composite materials derived from synthetic and bio-based materials. Particularly, the instrument will improve TU's research support infrastructure for investigating composite materials under low velocity impact. These low impact speeds are a major concern in the composites field because the resulting damage often goes undetected and can lead to catastrophic failure. It is also anticipated that the fundamental research studies enabled by this instrument will result in advancing the use of composite materials in automotive, aerospace, civil, defense, and other industrial applications. The instrument will be used by faculty and students at TU and collaborating partners, thereby encouraging synergistic research collaborations. In addition, a collection of course related projects and experiments will be made available to undergraduate and graduate students. Moreover, this instrument will play a critical role for TU to continue to produce a talented and well-qualified pool of African American STEM graduates. The failure mechanism under low velocity impact (LVI) is complex as the structure undergoes a series of failure modes: matrix cracking due to through thickness shear stresses, delamination due to mode II interlaminar shear stresses generated by the bending of laminate, and fiber fracture generated by the tensile bending stresses. In addition, the exposure of FRPCs to harsh environmental conditions will further adversely affect the LVI properties. Therefore, for the safe operation over the designed lifetime, LVI characterization of fiber reinforced composites (FRPCs) in regular and harsh conditions is extremely critical. An automated state-of-the-art Instron CEAST-9450 Drop Tower Impact Tester equipped with a thermostatic chamber is suited for testing FRPCs at elevated and cold temperatures. The specific studies that will be carried out using the impact tester include: damage behavior of jute and carbon/jute hybrid nanocomposites; impact performance of biomimetic helicoidal composite structures inspired by mantis shrimp; structural analysis of hybrid composites under fatigue, impact and ballistic loadings; durability of high temperature bismaleimide based carbon composites for aircraft applications; and design, fabrication, testing and analysis of thick composite joints. This equipment will serve as an excellent tool in developing the science and technology of FRPCs, while enhancing the research and education capabilities at Tuskegee University.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这项主要研究仪器(MRI)奖支持在塔斯基吉大学(TU)收购最先进的落塔冲击测试仪。该仪器将使从合成材料和生物基材料衍生的更坚固和耐用的复合材料的开发成为可能。特别是,该仪器将改善TU在低速撞击下研究复合材料的研究支持基础设施。这些低冲击速度是复合材料领域的一个主要问题,因为由此产生的损伤往往没有被发现,可能会导致灾难性的故障。预计该仪器的基础研究将推动复合材料在汽车、航空航天、民用、国防和其他工业应用中的应用。该仪器将由TU的教职员工和学生以及合作伙伴使用,从而鼓励协同研究合作。此外,还将向本科生和研究生提供一系列与课程相关的项目和实验。此外,这一工具将在TU继续培养一批有才华和合格的非裔美国STEM毕业生方面发挥关键作用。低速冲击(LVI)下的失效机理复杂,因为结构经历了一系列的失效模式:由贯穿厚度剪应力引起的基体开裂,由层板弯曲产生的II型层间剪应力引起的分层,以及由拉伸弯曲应力引起的纤维断裂。此外,FRPC暴露在恶劣的环境条件下将进一步对LVI物业产生不利影响。因此,为了在设计寿命内安全运行,纤维增强复合材料(FRPC)在常规和恶劣条件下的LVI特性是极其关键的。配备恒温室的自动化最先进的INSTRON CEAST-9450落塔冲击试验机适合在高温和低温下测试FRPC。将使用冲击试验机进行的具体研究包括:黄麻和碳/黄麻混杂纳米复合材料的损伤行为;以螳螂虾为灵感的仿生螺旋面复合材料结构的冲击性能;混杂复合材料在疲劳、冲击和弹道载荷下的结构分析;飞机用高温双马来酰亚胺基碳复合材料的耐久性;以及厚复合材料接头的设计、制造、测试和分析。该设备将成为发展FRPC科学和技术的极佳工具,同时加强塔斯基吉大学的研究和教育能力。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
