AbstractThe goal of this project is to develop a sustainable alternative to fiberglass load-bearing multi-purpose panels with novel cellular nano-biocomposites. Cellular nano-biocomposites. The cellular nano-biocomposite will be used to develop advanced panel components for multiple-use (i.e., housing floors, walls, roofs, bridge decks, RV panels) with tailorable integrated multi-functions (i.e., stiffness, strength, toughness, thermal insulation, fire protection, and user friendliness). The research objectives will be achieved through a fundamental study guided by four general tasks:I. Biobased Polyester Resin. Suitable biobased resin from a blend of petroleum-based polyester and functionalized soybean oil (~ 30 wt.%) is proposed to address both engineering and environmental requirements. II. Clay/Biobased Polyester Nanocomposite. The properties of biobased resin will be enhanced with nanoclay reinforcement dispersed via exfoliation. III. Nano-reinforced Polyester Biocomposite. The polymer nanocomposite will be additionally reinforced with "engineered" natural fibers. IV. Cellular Structural Material and Panel Systems. The specific properties of the nano-reinforced biocomposite will be further enhanced through the topological design of the material in cellular arrangements. The project is a multidisciplinary effort among the Departments of Civil and Environmental Engineering, Chemical Engineering and Materials Science, and Agriculture Economics. The research approach integrates the technical components of analysis, design and manufacturing with broad societal impact elements such as environment, economy, life-cycle analysis, energy, industrial collaboration, education integration, and outreach.The project will allow education and research training of two graduate and two undergraduatestudents. Research and education will be integrated in advanced composite materials courses across departments and through multidisciplinary student activities. A determined attempt will be made to recruit underrepresented students using university programs. We expect to create a break-through concept for a new generation of high-performance load-bearing components through fundamental research. The research will add considerable knowledge in the engineering of naturally reinforced nanocomposites, innovative structural design, and will create consciousness in designing value-added, eco-friendly and affordable materials and components for the 21-st century.

本项目的目标是开发一种可持续发展的新型细胞纳米生物复合材料多用途玻璃纤维承重板的替代品。细胞纳米生物复合材料。这种细胞纳米生物复合材料将用于开发先进的多用途面板组件(即房屋地板、墙壁、屋顶、桥面、房车面板)，具有可定制的综合多功能(即刚性、强度、韧性、隔热、防火和用户友好性)。研究目标将通过四项一般性任务指导的基础研究来实现：一、生物基聚酯树脂。从石油基聚酯和功能化大豆油(~30wt.%)的混合物中提出了合适的生物基树脂，以满足工程和环境要求。粘土/生物基聚酯纳米复合材料。通过剥离分散的纳米粘土增强生物基树脂的性能将得到提高。纳米增强聚酯生物复合材料。这种聚合物纳米复合材料还将用“工程”的天然纤维进行增强。四、蜂窝结构材料和板材系统。通过对材料进行胞状排列的拓扑设计，进一步提高了纳米增强生物复合材料的特性。该项目是土木工程和环境工程、化学工程和材料科学以及农业经济系之间的多学科努力。该研究方法将分析、设计和制造的技术要素与广泛的社会影响要素相结合，如环境、经济、生命周期分析、能源、产业合作、教育整合和外包。该项目将允许对两名研究生和两名本科生进行教育和研究培训。研究和教育将通过跨部门和多学科的学生活动整合到高级复合材料课程中。将坚决尝试利用大学课程招收代表性不足的学生。我们期待通过基础研究，为新一代高性能承重部件创造突破性的概念。这项研究将在天然增强纳米复合材料的工程、创新的结构设计方面增加相当多的知识，并将产生为21世纪设计增值、环保和负担得起的材料和部件的意识。
