项目摘要
9308498 Ramani Thermoplastic matrix fiber components are predominantly manufactured using intermediate material forms such as prepregs, tapes or towpregs, which reduces manufacturing and design flexibility, and increases the product costs. Even resins that are synthesized in powder form are converted to pellets and melt impregnated on glass fibers to manufacture short fiber composites. Several processing steps for the manufacture of the final component are wasteful from both manufacturing time, processing and design flexibility, and energy considerations. The primary objective of this research is to develop a single continuous process for impregnating and consolidating polymeric powders in continuous fibers to manufacture components to net shape. This process is extended to encapsulate ceramic powder with polymeric powder on continuous fibers. The impregnation is accomplished by electrostatic spray deposition and adhesion to the fiber tow, rapid heating, and consolidation in a filament winding or pultrusion process. Process models are developed for each sub-process and integrated during the process development cycle. Development and demonstration of this process will directly lead to minimizing the processing steps and reducing the associated costs. This process can be used for direct manufacture of filament wound, pultruded components and resin encapsulated glass fibers for injection molding and extrusion processes. Ceramic powder encapsulated tows can be used for the manufacture of continuous fiber ceramic composites and composites with ceramic particles as a filler in tribological situations.
Ramani热塑性基体纤维组件主要使用预浸料,胶带或拖浸料等中间材料形式制造,这降低了制造和设计的灵活性,并增加了产品成本。即使是以粉末形式合成的树脂也会转化为颗粒,并熔融浸渍在玻璃纤维上,以制造短纤维复合材料。从制造时间、加工和设计灵活性以及能源考虑来看,制造最终组件的几个加工步骤都是浪费的。本研究的主要目的是开发一种单一的连续工艺,用于在连续纤维中浸渍和巩固聚合物粉末,以制造净形状的组件。该工艺扩展到用聚合物粉末在连续纤维上封装陶瓷粉末。浸渍是通过静电喷涂沉积和粘附到纤维束上、快速加热和在长丝缠绕或拉挤过程中固化来完成的。为每个子过程开发过程模型,并在过程开发周期中进行集成。该工艺的开发和演示将直接导致最大限度地减少加工步骤并降低相关成本。该工艺可用于直接制造长丝缠绕、拉挤组件和树脂封装玻璃纤维,用于注塑和挤出工艺。陶瓷粉末包封束可用于制造连续纤维陶瓷复合材料和以陶瓷颗粒为填料的复合材料。
