A pultrusion method is known in which the pultruded fibers are introduced into a mold having a structure, pultruded into a desired cross-sectional shape, and then cured in a curing mold, but the cross-sectional shape of the structural reinforcing material is different. For each case, all the molds for hardening of Yuzu are required,
The work of replacing the mold is troublesome, the production cost is high, the drawn fiber body still cannot be cured, the fiber body cannot be passed through the curing mold at a faster speed, and the The method of lifting the curing mold using sound has the disadvantage that there is a limit to the increase in productivity.

得る。The above process is not particularly different from the conventional pultrusion method, but according to the characteristics of the present invention, the tape 6 is not shown on the outer periphery of the fibrous body 1 that has been pultruded from the inside of the mold 5. The fibrous body is wrapped and coated using a wrapping device or the like to control its shape, and then the fibrous body is cured while being transported inside the gold heating furnace 7, and when it is sufficiently hardened, it is taken out of the metal heating furnace 7. The n7'c fiber body 1 is cut to a desired length to obtain a structural reinforcing material.
チーゾロとしては、紙テープ、金属テープ或いは該繊維

好ましい。It is also preferable to apply a release material 8 to the tape 6 so that the tape 6 can be easily removed after the drawn fiber body 1 has hardened.
又、テープ6は、発泡の多い熱硬化性剤4を用いる場合
には有孔m造にしておくのが好ましい。Moreover, when using the thermosetting agent 4 which foams a lot, it is preferable that the tape 6 has a perforated structure.

Moreover, the conventional pultrusion method using a hardening mold can only achieve a manufacturing speed of about 0.1 to 3 m/min, whereas the present invention, which does not use a hardening mold, can achieve a manufacturing speed of only about 0.1 to 3 m/min. ,ba10
A production rate of about rn/min can be obtained with fl, 7'C0 and
Even when using a thermosetting material 4 that involves a condensation reaction such as phenol resin or alkali metal silicate, the gas generated within the drawn fiber body 1 is released to the outside through the gap between the wound NFC fibers. Therefore, no air bubbles are left inside the fiber body 1.

, m, the body is impregnated with a thermosetting material, introduced into a mold having a desired cross section, and pultruded into a desired cross-sectional shape;
In order to harden the drawn fiber body while regulating its shape by wrapping a tape around the outer circumference of the drawn fiber body,
No matter what cross-section the pultruded fiber body has, the tape is simply wrapped around its outer periphery to cover it, so unlike the conventional pultrusion molding method, there is no need for a mold for hardening the plants, and production costs can be reduced. Moreover, since the drawn fiber body can be cured while its shape is controlled while the tape is wrapped around the outer periphery of the body, it is not necessary to use the curing iron itself, and productivity can be improved.
