Embodiment 1
[0050] Tubular fiber layered preforms (such as figure 2 ) as an example, the inner diameter is 500mm, and the thickness of the preform is 28mm. Both the laminated yarn and the laminated yarn are made of quartz glass fiber, which adopts a shallow cross-bending fiber layered structure. The specification of the laminated yarn is 190Tex×4 strands, and the density is 9 strands / cm; the specification of the laminated yarn is 190Tex×7 strands, and the density 2 roots / cm.
[0051] Assuming that the outer diameter of the mandrel (model) of the tubular fiber layered structure preform is R, the thickness of the innermost unit is determined by the number of arrays of double-layered yarns, and the number of weekly units is M, which is the same as the number of arrays of double-layered yarns. The tubular fan-shaped unit (dividing the tubular fiber layered structure preform into equal-sized n equal parts, the smallest unit among them) changes in both the circumferential and radial thickness...
Embodiment 2
[0061] The preform is connected with tapered fiber layers (such as image 3 ) as an example, the inner diameter of the preform is 500mm, the cone angle (the angle between the busbar and the central axis) is 16 degrees, and the height of the cone section is 500mm. The thickness of the preform is 28 mm. The designed double-layered yarn and laminated yarn are all quartz glass fibers, and adopt a shallow cross-bending fiber layered structure. The specification of the double-layered yarn is 190Tex×4 strands, and the density is 9 strands / cm; the specification of the laminated yarn is 190Tex×7 strands. Density 2 / cm.
[0062] The thickness of the innermost unit of the preform determines the number of continuous-layer yarn arrays, and the number of units per week is the same as the number of arrays of continuous-layer yarn bundles. Equally divided, the smallest unit in it) changes with the change of radius and axial size. When the fan-shaped unit is equivalent to a parallelepiped u...
Embodiment 3
[0074] It is basically the same as Example 1, except that the thickness of the preform is 12mm.
[0075] The difference between Example 3 and the Comparative Example is that Example 3 is manufactured according to the mold and integrally formed, while the Comparative Example is offline unfolding and profiling. The epoxy resin of model GT-807A was used to compound the fabrics obtained in Example 3 and Comparative Example, and the mechanical properties of the composited fabrics are shown in Table 1.
