This Small Business Innovation Research (SBIR) Phase II project will develop the next generation of lightweight materials by utilizing recycled thermoplastic composites to achieve energy efficiency and impact protection for transportation and residential and commercial building applications. Previous work showed that combining fiberglass and thermoplastic face sheets and syntactic foam produced composite panels with greater impact resistance than plywood with aluminum facing. This work will expand the materials and processing envelope to produce a series of composite panels fabricated from recycled glass-reinforced/thermoplastic face sheets and a syntactic foam core consisting of glass or ceramic microspheres and regrind or virgin polymer. The use of hollow microspheres allows the achievement of both low weight and high impact strength while using low-cost extrusion-compression processing techniques. This configuration can be readily tailored to produce panel applications as varied as truck trailer bodies or for protection against flying debris caused by hurricane-force winds.The broader impacts of this research are the increased use of recycled materials to decrease the weight of commercial transport vehicles, resulting in increased fuel economy and decreased degradation of roadways and bridges. Also, improved systems for impact protection during hurricanes will result in less damage to commercial and residential structures and the loss of fewer lives. The technology of combining hollow ceramic microspheres from the ash of power plants with re-ground polymer waste will produce a material with unique properties that can be applied to a variety of commercial applications.

这个小型企业创新研究（SBIR）二期项目将通过利用回收热塑性复合材料开发下一代轻质材料，以实现交通、住宅和商业建筑应用的能源效率和冲击保护。先前的研究表明，将玻璃纤维和热塑性面板与合成泡沫相结合，产生的复合板比铝面板的胶合板具有更强的抗冲击性。这项工作将扩大材料和加工范围，以生产一系列由回收的玻璃增强/热塑性面板和由玻璃或陶瓷微球和再磨或原生聚合物组成的合成泡沫芯制成的复合板。空心微球的使用可以实现低重量和高冲击强度，同时使用低成本的挤压压缩加工技术。这种配置可以很容易地定制，以生产各种各样的面板应用，如卡车拖车车身或用于防止飓风造成的飞行碎片。这项研究更广泛的影响是增加了回收材料的使用，以减少商业运输车辆的重量，从而提高了燃料经济性，减少了道路和桥梁的退化。此外，改善飓风期间的冲击防护系统将减少对商业和住宅结构的破坏，减少生命损失。将来自电厂灰的空心陶瓷微球与再磨聚合物废料相结合的技术将产生一种具有独特性能的材料，可用于各种商业应用。
