The invention belongs to the technical field of bicycle frame machining processes, and relates to an integrally-formed carbon fiber bicycle frame process and application. The integrally-formed carbonfiber bicycle frame process comprises the steps: a mold is designed according to a product drawing, an integrated lost mold is manufactured, the surface of the lost mold is coated with a thin film, then standing and/or drying are/is conducted to obtain a glue film, the lost mold and the glue film are combined to form a core mold, and the core mold is rolled through cut carbon fiber cloth accordingto the lamination design requirement to obtain the integrally-formed carbon fiber bicycle frame. The core mold is manufactured, and then the carbon fiber bicycle frame is integrally rolled and molded, so that the continuity of the carbon fiber is effectively ensured, and the performance advantages of the carbon fiber composite material can be exerted. According to the process, bicycle frame production procedures are reduced, and the production cost is saved. According to the process, bicycle frame machining and gluing procedures are reduced, and the performance of the carbon fiber is kept stable. The strength of the bicycle frame manufactured through the process is remarkably improved on the premise of the same weight.

    本发明属于车架加工工艺技术领域,涉及一种整体成型碳纤维自行车架工艺及应用。一种整体成型碳纤维车架工艺,步骤为,根据产品图设计模具,制作一体式消失模,在消失模表面涂胶薄膜后静置和/或烘干得到胶膜,消失模和胶膜合称为芯模,芯模利用裁剪好的碳纤维布按照叠层设计要求卷制得到整体成型的碳纤维自行车架。本发明通过制作芯模,再进行碳纤维自行车架一体卷制、成型,有效保证了碳纤维的连续性,使得碳纤维复合材料能够发挥出其性能优势。本发明工艺减少了自行车架生产工序,节约生产成本。本发明工艺减少了自行车架机械加工和胶合的工序,使碳纤维性能保持稳定。采用本工艺制得的自行车架在相同重量的前提下强度得到显著提高。
