短纤纺技术用于处理碳纤维的可能性

摘要

Staple fiber technology offers a multitude of opportunities to process stretch broken or recycled carbon fibers. Especially the high flexibility in the production with regards to the yarn fineness and the yarn construction in combination with the possible lower costs for the raw materials emphasize the potential of the staple fiber technology in the large batch production of CFRP. The material parameters can be optimized to the application. New processes in staple fiber spinning, such as the tape production can bring forth more advantages beyond conventional methods, e. g. through a process shortening in spinning or an increase of productivity in further processing. Besides the economic advantages of staple fiber products, many opportunities for the optimization of the material properties in view of the fields of application arise.%短纤维技术为处理拉伸断裂的或再利用的碳纤维提供了多种可能，尤其是与可能的低成本原料混合生产时，在纱线细度和纱线结构方面能体现出高度灵活性，着重体现了短纤维技术在碳纤维复合材料大批量生产中的潜能。材料参数可根据应用优化。新的短纤加工技术(如扁丝生产)比传统技术具有更多优势，如通过一项处理可缩短纺纱时间，或在后续加工中提高生产效率。除短纤维产品的经济优势外，应用领域中许多优化材料性能的机会也逐渐显现。
