Abstract: The preforms of SiC fiber (SiC_f)/SiC composite cladding were fabricated by winding forming process under the layering scheme of one hoop layer + one spiral layer, hoop layer yarn width of 1.1 mm, spiral layer yarn width of 0.85 mm, spiral layer winding angle of ±45°, one cut point, and winding tension of 0–5 N. The optimal winding tension of the preform was determined by the requirements of the wall thickness （0.45–0.56 mm）, fiber volume fraction （45%–55%）, and surface quality of the preform. By changing yarn width and winding angle of the spiral layer, the theoretical thickness of preforms was calculated, and preform layering schemes that met the wall thickness requirements were obtained. The preforms were prepared, and the influence of the winding angle of the spiral layer and the number of cut points on wall thickness and fiber volume fraction was studied. After pyrolytic carbon, chemical vapor infiltration （CVI） and chemical vapor deposition （CVD） on preforms, the cladding was obtained. The density, porosity, circumferential and axial strength of the prepared cladding under different layering schemes were compared and studied, and the superior layering scheme was determined. The results show that the optimal winding tension was 3 N, and the surface of the preform was flat, the yarns were evenly arranged, the wall thickness was 0.5 mm, and the fiber volume fraction was 50%. The larger the spiral layer winding angle, the greater the the amount of protrusions on the surface of the cladding, and the poorer the surface quality. The increase in the number of cut points led to more fiber bridging and voids in the preform, which had a positive effect on CVI densification, and the porosity of the prepared cladding decreased. The layering schemes that met the preform wall thickness requirement were one hoop layer + one spiral layer, hoop layer yarn width of 1.1 mm, spiral layer yarn width of 0.85 mm, winding angle of ±40°, and three cut points （Scheme 1）, and one hoop layer + two spiral layers, hoop layer yarn width of 1.1 mm, spiral layer yarn width of 1.35 mm, winding angle of ±35°, and three cut points （Scheme 2）. The axial strength and porosity of the prepared cladding under Scheme 1 did not meet the index requirements, while the performance of the prepared cladding under Scheme 2 met the index requirements, with a hoop strength of 197 MPa, an axial strength of 235.2 MPa, a porosity of 6.45%, and a density of 2.87 g·cm⁻³.
