一种连续功能化碳纤维增强热塑性树脂基预浸带的制备工艺
摘要：
本发明涉及一种连续功能化碳纤维增强热塑性树脂基预浸带的制备工艺，主要包括导纱、添加树脂、热压成型以及收卷工序，所述的功能化碳纤维主要指已经表面处理后的碳纤维；所述的导纱和所述的添加树脂之间增加功能化碳纤维的开纤工序；或者在所述的导纱之后增加开纤工序，开纤时添加树脂；所述的添加树脂是指将热塑性树脂粉体悬浊液喷洒到已开纤的功能化碳纤维上。本发明在添加热塑性树脂前增加开纤工艺，并在添加热塑性树脂时针对所述的功能化碳纤维选用喷洒含热塑性树脂粉体的悬浊液的方式从而有效控制预浸料带树脂含量，制备较为均一的，孔隙率低的连续功能化碳纤维增强热塑性预浸带。
摘要（英）：

The invention relates to a preparation technology of a continuous functionalized carbon fiber enhanced thermoplastic resin tape. The technology comprises the following steps: yarn guiding, resin adding, hot press moulding, and reeling; the functionalized carbon fiber is prepared by subjecting carbon fiber to a surface treatment; a functionalized carbon fiber splitting process is added between the yarn guiding process and the resin adding process; or the splitting process is added behind the yarn guiding process, and resin is added during the splitting process; and during the resin adding process, thermoplastic resin powder suspension is sprayed over the splitted functionalized carbon fibers. A splitting process is added before the addition of thermoplastic resin and during the thermoplastic resin addition process suspension containing thermoplastic resin powder is sprayed over the functionalized carbon fibers so as to effectively control the prepreg tape resin content, and finally uniform and low porosity continuous functionalized carbon fiber enhanced thermoplastic prepreg tape is obtained.
