Further, in the auxiliary structure, the reinforcing fibers are arranged such that they have a predetermined intersecting angle and intersect with each other from three directions or more on the same plane, so that it is not only the axial direction of the corpus callosum or the circle φ of the corpus callosum. In the direction, since the reinforcing fibers are also disposed in the oblique direction, the resistance to the bending force or the shearing force applied to the body is strong. [Effects] It is possible to suppress deformation or cracking in the joint portion between the small-diameter side body and the large-diameter side body. And the 'auxiliary structure is not set to cover the full length of the carcass, but is limited to the front end and the end of the crotch. In this way, the strength of the joint portion φ can be increased, and the reinforcing fibers can be arranged in a direction in which the reinforcing fibers are arranged in three or more directions from a direction of three or more directions to have a predetermined intersecting angle, and the pinhole phenomenon can be suppressed.

According to a third aspect of the invention, the intermediate layer is an inner intermediate layer located at the innermost side in the plurality of intermediate layers, the width of one circumference of the shaft is wound, and the inner side of the first main structure in the direction of the circumferential direction of the strong body The outer middle layer on the outer side of the layer is a shape in which the width of the circumference of several times of the circumference is several times longer in the direction along the axial direction of the body, and is disposed at the corresponding position on the front side of the crucible. The structure is wound around the mandrel, and the corresponding position on the front side of the main crucible and the crucible structure are arranged such that the main structure is wound at a predetermined crossing angle, and the front end portion and the crucible of the reinforcing fiber are disposed by the direction. In the main structure of the tail end, the layer portion of the crucible which exhibits a stable strength is further constituted by the fact that the core fiber is disposed along the crucible, and the core portion has the core axis. And the main structure of the reinforcing fiber is configured, and the effect of (5) 1333833 is as follows. [Effects] The method of constituting the intermediate layer as the inner intermediate layer is a first main structure obtained by cutting a prepreg having reinforcing fibers along the circumferential direction of the corpus callosum, and When the impregnating material is wound around the mandrel and formed into a tubular shape, the reinforcing fibers disposed in the circumferential direction exhibit a tensile strength of φ and prevent the prepreg from being broken in the circumferential direction. Thereby, since the circumferential direction strength of the prepreg located inside is reinforced, even if the outer intermediate layer is wound around the inner intermediate layer, it can be stably performed. In addition, since the second main structure composed of the prepreg in which the reinforcing fibers are arranged in the axial direction of the crucible is disposed as the outer intermediate layer, the relative orientation is caused by the load of the fish. In the case of the bending moment in the case of bending, the above-mentioned reinforcing fiber can exert a resistance. φ By providing the reinforcing fibers in the inner middle layer in the circumferential direction of the crucible and the outer intermediate layer in which the reinforcing fibers are arranged in the axial direction of the crucible, it is possible to provide a strong resistance to cracks in the crucible body. Construction. According to a fourth aspect of the invention, the intermediate layer is formed in three layers, and the first intermediate layer located in the innermost layer in the intermediate layer has a width of one turn corresponding to the circumference of the mandrel, and the reinforcing fiber is disposed. The first main structure is formed in a direction along the circumferential direction of the body; and the second intermediate layer located outside the first intermediate layer is: -9- (6) having a circumference corresponding to the mandrel 1333833 several times the width of a plurality of turns, and the reinforcing fiber is disposed in a second main structure in a direction along the axial direction of the body, and the third intermediate layer located on the outer side of the second intermediate layer The strip-shaped prepreg tape having a short axial length along the axial direction of the corpus callosum is composed of a strip body wound around the entire length of the corpus callosum, and the effect is as follows. [Effects] B In addition to the effects of the third invention, the following effects are obtained. According to the fourth aspect of the invention, the prepreg tape is wound around the outer side of the second intermediate layer as the third intermediate layer. Thereby, the pre-impregnated belt exerts the force of tightening, which will cover the entire length of the carcass. Thereby, the occurrence of loss of voids or the occurrence of pinholes caused by the voids can be suppressed.

As shown in Fig. 1, the first main structure 3 is a prepreg obtained by impregnating a reinforcing fiber group such as carbon fiber aligned in a single direction and impregnating a thermosetting resin such as an epoxy resin, and cutting it into a predetermined one. Shape formed. -13- 1333833 do) The prepreg is a structure in which a reinforcing fiber such as carbon fiber is aligned in the circumferential direction of the crucible, and a thermosetting resin such as an epoxy resin is immersed in a reinforcing fiber arranged in a neat manner. Cut into: the length in the axial direction along the axial direction of the body is longer than the axial length of the auxiliary structures 1, 5, and the width d along the circumferential direction of the body is wound around the mandrel The width of one layer of 2. As shown in Fig. 1, the second main structure 4' is formed to have a structure substantially the same as that of the first main φ structure 3, but is cut so that the direction of the reinforcing fibers aligned in a single direction is set to the corpus callosum. The axial direction, and the width D along the circumferential direction of the body is the width of the plurality of layers wound on the mandrel 2 in a plurality of turns. As shown in Fig. 1 (β), the above-described auxiliary structures 1 and 5 and the main structures 3 and 4 are superposed and wound to form a crucible. In the state in which the above-described body A is joined into the drawn body, the protrusion # of the auxiliary structure 5 of the end portion of the small diameter body and the front end of the large diameter body are assisted. When the fitting portions formed by the structure 1 are pressed together, the joined state can be tightened, and since the reinforcing fibers constituting the auxiliary structures 1 and 5 are arranged in a direction inclined to the axis of the body, the front end portion or the crucible can be suppressed. The crack at the end. [Second Embodiment] As shown in Fig. 4, a place different from the first embodiment 'after the second main structure 4 is packaged, and before the second auxiliary structure 5 is packaged, covers the entire length of the carcass Wound: a long pre-impregnated strip 6 having a length of -14 (11) (11) 1,333,383 degrees along the axial direction of the crucible body as a third intermediate layer.

With the above configuration, the innermost layer is configured with the first auxiliary structure 1, the intermediate layer is configured with two main structures 3, 4 and the prepreg strip 6, and the outermost layer is configured with the second auxiliary structure 5 to constitute the crucible. Body A. [Third Embodiment] As shown in Fig. 5, the first auxiliary structures 1 and 1 are disposed in the same manner as the first end portion and the end portion of the crucible are wound around the mandrel 2. On the outer side of the first auxiliary structure 1, 1, the long pre-impregnated tape 6 is wound around the entire length of the carcass. The reinforcing fibers of the prepreg tape 6 are disposed in the circumferential direction of the carcass. Next, on the outside of the prepreg tape 6, the above-described second main structure 4 is wound, and the above-described second auxiliary structures 5, 5 are wound. The full length wound prepreg tape 7 of the carcass is covered on the outside of the second auxiliary structure 5. The reinforcing fibers of the prepreg tape 7 are arranged in the circumferential direction of the carcass. With the above configuration, the innermost layer is the first auxiliary structure 1 disposed, the intermediate layer is the main structure 4 and the prepreg tape 6, the outer intermediate layer is the second auxiliary structure 5, and the outermost layer is the prepreg.
