This Small Business Technology Transfer (STTR) Phase I project will develop a new class of lightweight, multi-functional structural panels with improved performance (strength, stiffness, high impact energy dissipation, thermal management) at minimum weight. The proposed work considers a novel approach to the design and manufacture of truss core sandwich structures, involving discrete-pin placement allowing for a unique topological arrangement of truss core elements for enhanced combination of mechanical and physical properties. The program will: (1) demonstrate the fabrication approach, (2) compare mechanical performance with existing sandwich panel concepts, and (3) develop performance maps and computational protocols for application-specific panel design. Specific comparisons will be made between solid-truss and hollow-truss sandwich panel designs. This research partnership effort between Cellular Materials International and the University of California, Irvine will expand understanding of optimal panel design, promote expanded applications, and eliminate existing topological constraints on multi-functional structural materials usage. The freedom to tailor variable core thickness, core density, materials makeup, and thermo-mechanical response while allowing for complex curvature will highly enhance/broaden the use of sandwich panels in applications involving high energy impact, ballistic/blast mitigation, thermal exchange, and damping of sound and vibrational energy. Typical commercial applications may include lightweight aerospace structures, thermally efficient heat exchangers, lightweight vehicle armor, space vehicle skin structures, energy-dissipating automobile bumpers/frames, and earthquake- or blast-resistant structural walls for high profile buildings. Additional broader impacts include recruiting and training the workforce needed to enhance U.S. leadership in advanced materials and structures, and increasing participation of underrepresented K-12 and undergraduate students in engineering. This program also will enable the infrastructure for advanced materials characterization, synthesis and integration for critical commercial, civil and military systems.

该小型企业技术转让 (STTR) 第一阶段项目将开发新型轻质多功能结构板，以最小的重量提高性能（强度、刚度、高冲击能量耗散、热管理）。拟议的工作考虑了一种设计和制造桁架核心夹层结构的新颖方法，涉及离散销的放置，允许桁架核心元件的独特拓扑排列，以增强机械和物理性能的组合。该计划将：(1) 演示制造方法，(2) 将机械性能与现有夹层板概念进行比较，以及 (3) 为特定应用的面板设计开发性能图和计算协议。将在实心桁架和空心桁架夹芯板设计之间进行具体比较。细胞材料国际公司和加州大学欧文分校之间的这项研究合作将扩大对最佳面板设计的理解，促进扩大应用，并消除对多功能结构材料使用的现有拓扑限制。自由定制可变的芯厚度、芯密度、材料构成和热机械响应，同时允许复杂的曲率，将极大地增强/拓宽夹芯板在涉及高能冲击、弹道/爆炸缓解、热交换以及声音和振动能量阻尼的应用中的使用。典型的商业应用可能包括轻型航空航天结构、热效率热交换器、轻型车辆装甲、航天器蒙皮结构、耗能汽车保险杠/框架以及高层建筑的抗震或防爆结构墙。其他更广泛的影响包括招募和培训加强美国在先进材料和结构领域的领导地位所需的劳动力，以及增加代表性不足的 K-12 和本科生对工程的参与。该计划还将为关键商业、民用和军事系统提供先进材料表征、合成和集成的基础设施。
