全体を軽くできるのである。(Function) Since there is a thickening layer (2) on one side in the radial direction of the high-strength fiber layer (1), it is possible to increase the overall wall thickness per unit weight.
The bending strength per unit weight can be increased, and since the thickened layer (2) includes a large number of micro hollow spheres and hardly contributes to the tension, the tension against the increased thickness is reduced. The increase in bending strength can be made very small, making it easy to bend, and the increase in weight due to the increase in bending strength can be minimized, making the overall weight lighter.

ト（Ｓ）の端面から外方に流出してしまう恐れがある。Thus, the tubular body constructed as described above is obtained by winding the prepreg (P) around the outer periphery of the core bar so that the fiber direction of the aligned high-strength fibers is the length direction. )
A thickening layer (2) is formed by winding a synthetic resin sheet (S) with micro hollow spheres interposed around the outer periphery of this high-strength fiber jl (1'). Then, a cellophane tape is wrapped around the outer periphery of the thickening layer (2) to bind the high-strength fiber layer (1) and the thickening layer (2), and the high-strength fiber layer is heated and fired in a heating furnace. (1) and the thickening layer (2) are integrally combined. In addition, the synthetic resin sheet)
The microscopic hollow spheres in (S) are very small, 5 to 150μ, and the thermosetting synthetic resin interposed with these microscopic hollow spheres melts when hardened by the baking process, resulting in a low viscosity. In this case, there is a risk that the micro hollow spheres may flow outward from the end surface of the sheet (S).

Then, during firing, the synthetic resin sheet (
It is preferable to prevent the micro hollow spheres in S) from flowing outward from the sheet end surface.

くできるのである。In this way, the high-strength fiber layer (1) can provide a predetermined bending strength, and the thickening layer (2) can increase the wall thickness relative to the unit weight, so the bending strength relative to the unit weight can be increased. The strength can be increased. Furthermore, since the micro hollow spheres of the thickening layer (2) hardly contribute to the tension of the tubular body that is not dispersed and intervening, the increase in tension due to the thickening layer (2) is extremely important. It can be made smaller and easier to bend.

The bending strength with respect to weight and the bending with respect to tension (rigidity) of the tubular body (A) and the tubular body (B) in which the thickening layer (2) is laminated inside the high-strength fiber layer (1) in the radial direction. When comparing the strength, as shown in Figures 5 and 6, according to the present invention, the bending strength against weight can be increased compared to the conventional tubular body (C), and the bending strength against tension can also be increased. This makes it possible to form a tubular body that has low tension, is easy to bend, is lightweight, and has high bending strength.

強度増大に対する重量増大を最小にでき、軽くて、曲げ
強度の大きい管状体を形成できるのである。(Effects of the Invention) As described above, according to the present invention, a large number of fibers are formed on one side in the radial direction of the hollow high-strength fiber layer (1) made of high-strength fibers wrapped with prepreg impregnated with a synthetic resin. By laminating thickening layers (2) made of synthetic resin with micro hollow spheres interposed between them, it is possible to increase the overall wall thickness relative to unit weight, so it is possible to increase the bending strength relative to unit weight, and this bending strength This makes it possible to minimize the increase in weight and form a light tubular body with high bending strength.
しかも、前記増厚層（２）は、多数の微小中空球体が介
在されていて、張りに対しては殆んど寄与しないので、
増厚に対する張りの増大を非常に小さくでき、従って、
曲がり易くて、曲げ強度の大きい管状体を形成できるで
ある。Moreover, the thickening layer (2) has a large number of micro hollow spheres interposed therein and hardly contributes to the tension.
The increase in tension with respect to the increase in thickness can be made very small, and therefore,
A tubular body that is easy to bend and has high bending strength can be formed.
