项目摘要
The objective of this research is to utilize an integrated analytical, experimental and numerical effort to attain a fundamental understanding of two governing physical phenomena - interlayer (fabric-fabric) friction and interconnected through-thickness and in-plane compaction. Modeling of the in-service performance of thermoplastic-matrix woven-fabric reinforced structural composites - e.g., damage tolerance, crashworthiness, vibration - is currently inadequate for parts of any geometric complexity because of the inability of existing performance models to capture the true deformed material properties. The key to taking advantage of the reduced weight and potentially increased occupant safety that these composites can offer is to provide a direct link between part geometry, material selection, process conditions, process-induced local properties, and part performance, thereby allowing informed feedback to the design process. The capabilities of the predictive model will be demonstrated by considering a prototype part from design conception, to manufacturing under a set of prescribed conditions, through seamlessly examining its in-service performance. This research is being cosponsored by the DOE Freedom Car Project. The availability of a predictive model that can be widely used by industry will facilitate the greater use of lightweight composite materials in the automotive industry, increasing fuel-efficiency without sacrificing safety. In coordination with the overall theme of processing-structure-performance interrelations, outreach efforts are planned to develop new sessions on "Design, Fabrication, and Testing of Braided Composite Baseball Bats" for grade 8-10 participants in the extremely successful UMass-Lowell Design Camp. A similar summer-session collaboration with Cislunar Aerospace, Inc. is planned for introducing girls to science and engineering through examples of aerodynamics in sports. In addition, all undergraduate and graduate students in this project will have the opportunity for extensive interactions with our industry (Ford, GM) and international (Belgium, UK, France) partners.
本研究的目的是利用综合的分析,实验和数值努力来获得对两种主要物理现象的基本理解-层间(织物-织物)摩擦和相互连接的厚度和面内压实。热塑性基质机织织物增强结构复合材料的使用性能建模-例如,损伤容忍度,耐撞性,振动-目前不适合任何几何复杂性的部件,因为现有的性能模型无法捕捉真实的变形材料特性。利用这些复合材料减轻重量和潜在提高乘员安全性的关键是在零件几何形状、材料选择、工艺条件、工艺诱发的局部特性和零件性能之间提供直接联系,从而允许对设计过程进行知情反馈。预测模型的能力将通过考虑原型部件从设计概念到在一组规定条件下的制造,通过无缝检查其在役性能来证明。这项研究是由美国能源部自由汽车项目共同赞助的。预测模型的可用性可以广泛应用于工业,这将有助于在汽车工业中更多地使用轻质复合材料,在不牺牲安全性的情况下提高燃油效率。与加工-结构-性能相互关系的总体主题相协调,计划为马萨诸塞大学-洛厄尔设计营非常成功的8-10年级参与者开发新的“编织复合材料棒球棒的设计,制造和测试”课程。计划与月球航空航天公司(Cislunar Aerospace, Inc.)合作举办一个类似的夏季课程,通过运动中的空气动力学例子向女孩们介绍科学和工程。此外,该项目的所有本科生和研究生都将有机会与我们的行业(福特,通用)和国际(比利时,英国,法国)合作伙伴进行广泛的互动。
