Abstract: In order to solve the problems of insufficient continuous fiber and circumferential mechanical properties of needled carbon/carbon crucible, a prefabricated carbon/carbon crucible reinforced with carbon fiber was used. Based on the non-geodesic theory, the stable winding equation was established. Based on the tangential point method and the standard line method, the winding linear law of the non-axisymmetric head shell was summarized. The calculation formula of the center rotation angle when the fibers were uniformly filled was derived. The linear design process of carbon fiber winding reinforced by carbon crucible preform was proposed. Under the condition of equal suspension length, the work trajectory equations of four axis winding machine were solved. The effects of tangent points on winding line and winding machine trajectory were studied by simulation. The results of winding tests show that the fiber can be continuously and stably wound, and the fiber can be uniformly covered after a certain cycle. The correctness of the motion trajectory equation of each axis and the feasibility of the linear design method are verified.
