*** 9760568 Sherman This Small Business Innovation Research Phase I program will demonstrate the ability to fabricate a low cost titanium foam structural material. The resulting syntactic foam will offer improved structural efficiency without the limitations of currently available honeycomb core sandwich structures by improving the properties (primarily shear) of the core material and the care/facesheet bond. The primary objectives of the proposed program will be demonstrating improvements in structural efficiency and design flexibility that can be achieved using a titanium foam core sandwich panel, while, eliminating current sandwich panel design limitations. Powdermet will demonstrate the fabrication of syntactic titanium foam with 50-80% microsphere loadings using metal encapsulated ceramic microspheres prepared using chemical vapor deposition and consolidated through either sintering or a modified OSPREY process. The end result will be a low cost, high strength and structurally efficient syntactic titanium foam composite material. Aside from the obvious airframe applications of sandwich panels (a multibillion-dollar market), commercial spinoffs in spacecraft, sporting equipment, robotics, medical implants, automobiles, and other critical stiffness-driven material applications, as well as other specialized markets including filters and noise suppression structures, represent tremendous commercial potential for a reliable foam core sandwich structure. ***

谢尔曼酒店 该小型企业创新研究第一阶段计划将展示制造低成本钛泡沫结构材料的能力。 所得复合泡沫塑料将通过改善芯材料的性能（主要是剪切）和保养/保养粘合而提供改善的结构效率，而没有目前可用的蜂窝芯夹层结构的限制。 该计划的主要目标是展示使用钛泡沫芯夹层板可以实现的结构效率和设计灵活性的改进，同时消除当前夹层板设计的限制。 Powdermet将展示使用金属封装陶瓷微球制造50-80%微球负载的复合钛泡沫，该微球使用化学气相沉积制备，并通过烧结或改进的OSPREY工艺进行固结。 最终结果将是低成本、高强度和结构有效的复合泡沫钛复合材料。 除了夹层板的明显机身应用（数十亿美元的市场），航天器，运动设备，机器人，医疗植入物，汽车和其他关键刚度驱动材料应用的商业副产品，以及其他专业市场，包括过滤器和噪音抑制结构，代表了可靠的泡沫芯夹层结构的巨大商业潜力。 ***
