Forming method of cone-shaped prefabricated body with unequal wall thickness
The invention relates to a forming method of an unequal-wall-thickness conical preform, belongs to the technical field of preparation of fiber reinforced ceramic matrix composite components, and solves the problems that a three-dimensional woven unequal-wall-thickness conical preform is long in forming period and high in cost; the transition section of the prefabricated body is unequal in wall thickness and difficult to shape; the method comprises the steps of graphite mold punching, high-temperature treatment, inner mold assembly, first-time carbon fiber cloth laying, second-time silicon carbide cloth laying, third-time silicon carbide cloth laying, fourth-time silicon carbide cloth laying and fifth-time carbon fiber cloth laying, and further comprises the steps of graphite mold punching, high-temperature treatment, inner mold assembly, first-time carbon fiber cloth laying, second-time silicon carbide cloth laying, third-time silicon carbide cloth laying, fourth-time silicon carbide cloth laying and fifth-time carbon fiber cloth laying. And sewing the prefabricated body and the inner mold, and closing the mold. The forming method is used for preparing the cone-shaped preforms with the unequal wall thicknesses.
本发明涉及一种不等壁厚锥体形状预制体的成型方法，属于纤维增强陶瓷基复合材料构件制备技术领域，解决三维编织不等壁厚锥形预制体成型周期长、成本高；预制体过渡段不等壁厚难以定型；内外模之间无相互连接关系导致的复合材料壁厚变化及褶皱变形的技术问题，其包括石墨模具打孔、高温处理，内模模具组装，第一次铺碳纤维布，第二次铺碳化硅布，第三次铺碳化硅布，第四次铺碳化硅布，第五次铺碳纤维布，预制体与内模模具缝制，合模的步骤。该成型方法用于不等壁厚锥体形状预制体的制备。
