This Early Faculty Career (CAREER) development plan will address the increasing needs of the aerospace, naval, automotive, medical and other industries for advanced materials to provide the lightweight and high strength components. A new high strength ultra-light material will be developed, processed, and tested. This research is divided into three main tasks: (1) new closed cell metallic foam with a uniform cell structure will be processed using preform hollow spheres. This will lead to an improvement of the cyclic lifetime of the material. (2) Fiber reinforced metal matrix preform wires will be embedded into the new foam structure with the goal of providing higher strength materials. (3) The new fiber reinforced metallic foam will be mechanically tested and its deformation behavior will be mapped. At this stage if the properties of the material need any improvement, the processing techniques will be tailored to address those issues. The results will be presented in a variety of conferences and workshops. The education plan for this project involves four complementary initiatives: (1) Collaboration with international universities to expose the students to international issues. (2) Course development in advanced materials, including metallic foaming presented over the Internet for distance learning purposes. (3) Recruiting underrepresented and/or female students in local colleges and high schools. (4) Undergraduate students will become involved in this research through an undergraduate Independent Research Project course. Graduate students will be involved in coordinating the undergraduate research course and it will contribute to the integration of undergraduate and graduate education. The research project will work towards developing collaborations, new teaching courses, presentations and seminars to strengthen not only the knowledge of the participants, but also the broader audiences. The technical outcome of this work is on producing new ultra-light, high-strength materials that eventually will benefit the society through great impact on improved fuel economy, energy consumption, safety and reduced maintenance of moving structures

该早期教师职业（CAREER）发展计划将满足航空航天，海军，汽车，医疗和其他行业对先进材料日益增长的需求，以提供轻质和高强度的组件。 一种新的高强度超轻材料将被开发、加工和测试。 本研究主要分为三个方面：（1）利用预制空心球制备出具有均匀泡孔结构的新型闭孔泡沫金属。 这将导致材料的循环寿命的改善。 (2)纤维增强金属基预制丝将嵌入新的泡沫结构中，目的是提供更高强度的材料。 (3)新的纤维增强金属泡沫将进行机械测试，并绘制其变形行为。 在这个阶段，如果材料的性能需要任何改进，加工技术将被定制以解决这些问题。 研究结果将在各种会议和讲习班上介绍。该项目的教育计划包括四项互补举措：（1）与国际大学合作，让学生接触国际问题。 (2)在因特网上为远距离学习目的开设先进材料课程，包括金属发泡。(3)在当地大学和高中招收代表性不足的学生和/或女生。 (4)本科生将通过本科独立研究项目课程参与这项研究。 研究生将参与协调本科研究课程，这将有助于本科和研究生教育的整合。该研究项目将致力于发展合作，新的教学课程，演示文稿和研讨会，以加强不仅参与者的知识，而且更广泛的受众。 这项工作的技术成果是生产新的超轻，高强度材料，最终将通过改善燃油经济性，能源消耗，安全性和减少移动结构的维护来造福社会
