This Small Business Innovation Research Phase I project will develop a new method of radiation welding of high performance thermoplastic reinforced composites without degrading the core fiber material. Conventional methods of thermal welding of this type of composite cause degradation of the composite core fiber and lose of strength at the welding seam. Two innovative technologies are integrated to accomplish this proposal. The first is the development of a multi-layer thermoplastic reinforced composite structure to insulate the core fiber from heat exposure during welding. The second technology is construction of a welding unit that projects selective near infrared radiation throughout the tertiary structure of the composite interface to weld the composites. The broader impacts of this technology could be the commercialization would be weldable composite technology and a welding that could significantly expand applications of thermoplastic reinforced composites (TRC) by providing a high speed assembly and joining process that can meet mass production requirements. TRC based parts that can reduce weight while maintaining strength, be more easily recycled and be assembled using high speed welding technology will create new product uses in military, commercial and industrial applications. New forms of thin sheet TRC are being integrated into the aerospace manufacturing, especially in construction of high altitude airships and balloons. Automobile manufacturers are seeking light-weight composites that are more easily recycled to reduce the weight requirements while maintaining strength in automobiles. Weldable TRC made with a thermoplastic core fiber can potentially meet these needs. Expanded use of TRC recycled parts will benefit the environment. Longer term, the welding process could provide a new competitive manufacturing technology that could drive job expansion and growth in the U.S. economy.

这个小企业创新研究一期项目将开发一种新的辐射焊接方法，用于高性能热塑性增强复合材料，而不会降解核心纤维材料。这种复合材料的传统热焊接方法会导致复合材料芯纤维的退化和焊缝强度的损失。两种创新技术被整合在一起来完成这个提议。首先是开发一种多层热塑性增强复合材料结构，使核心纤维在焊接过程中免受热暴露。第二种技术是建造一个焊接单元，在整个复合材料界面的三级结构上投射选择性的近红外辐射来焊接复合材料。这项技术的更广泛影响可能是商业化的可焊接复合材料技术和焊接，可以通过提供高速组装和连接工艺来满足大规模生产要求，从而显着扩展热塑性增强复合材料（TRC）的应用。基于TRC的部件可以在保持强度的同时减轻重量，更容易回收和使用高速焊接技术组装，将在军事，商业和工业应用中创造新的产品用途。新形式的薄板TRC正被集成到航空航天制造中，特别是在高空飞艇和气球的建造中。汽车制造商正在寻求更容易回收的轻质复合材料，以减少重量要求，同时保持汽车的强度。由热塑性芯纤维制成的可焊接TRC可以潜在地满足这些需求。扩大使用储物中心回收的零件对环境有利。从长远来看，焊接工艺可以提供一种新的有竞争力的制造技术，可以推动就业机会的扩大和美国经济的增长。
