碳纤维复合材料假脚的成型工艺制造技术

本发明专利技术涉及一种碳纤维复合材料假脚的成型工艺，包括预浸料、裁剪、铺层、热成型、打磨和喷砂。预浸料包括单向碳纤维预浸料、３Ｋ碳纤维束编织布预浸料、树脂膜，然后把上述预浸料裁剪成所需形状。铺层环节尤为重要，把预浸料按铺层方式贴合在模具上形成预成型体，在铺层过程中设置中间层，单向碳纤维预浸料按不同方向交替铺层且关于中间层对称，用电熨斗把树脂膜均匀熔渗于预成型体中。在热成型环节中，类平板的部件采用模压成型，弧度较大的部件采用袋压成型。脱模后，对成型的假脚进行打磨和喷砂处理。使用本发明专利技术生产的复合材料假脚具有整体强度高、质量轻、耐疲劳、弹性好、与连接件配合好、几何结构匀称、热稳定性好、变形量小等优点。

Forming process of carbon fiber composite false foot

The invention relates to a molding process of a carbon fiber composite material false foot, which comprises prepreg, cutting, laying, thermoforming, polishing and sand blasting. The prepreg comprises unidirectional carbon fiber prepreg, 3K carbon fiber bundle, woven fabric prepreg, resin film, and then cut the prepreg to the desired shape. Link layer is particularly important, the prepreg by layers attached to the mold forming preform, intermediate layer is disposed on the layer in the process of unidirectional carbon fiber prepreg according to different layers and alternating direction on the middle layer is symmetrical, with an electric iron to resin film uniform infiltration in the preform. In the hot forming process, the parts of the flat plate are molded by compression molding, and the larger radian parts are molded by bag pressure. After demoulding, the molded feet are polished and sand blasted. The composite material made by the invention has the advantages of high integral strength, light quality, good fatigue resistance, good elasticity, good coordination with the connecting parts, symmetrical geometrical structure, good thermal stability, small deformation, etc..
