It can sufficiently withstand bending force and impact force, and can be used, for example, as lightweight hollow frames and mechanical parts in the fields of aviation, space, automobiles, ships, and railways, as well as columns, piping materials, and internal pressure in the civil engineering and construction fields. It can be used as a lightweight structural material in various other fields, such as hollow structural materials such as containers.

た。′−Δ growth. Traditionally, long and lightweight structural materials have been required in the various fields mentioned above, and carbon fiber, glass, etc. have traditionally been used as such structural materials.
Fiber-reinforced composite materials using a-fibers as reinforcing fibers have been proposed. In order to further reduce weight, composite materials are formed into hollow pipe shapes, and in order to further reduce weight, the wall thickness of hollow pipes tends to be thinner, but as the wall thickness becomes thinner, the bending strength and compressive strength increase. This resulted in a decrease in impact resistance, and there was a limit to how thin the wall could be made. Further, when the wall thickness of such a hollow pipe made of a composite material is reduced, airtightness is lost, and when such a pipe is used as a piping material, there is a problem in that fluid leaks to the outside. Furthermore, especially in pultrusion molding, problems such as damage to the molded product inside the mold and at the pull-out portion occur, making molding difficult.

It is possible to realize long, lightweight hollow fiber-reinforced composite resin molded products that can sufficiently withstand compressive force, bending force, and impact force.

。In addition, the elongated thin-walled hollow tube can function as a mandrel when manufacturing molded products by pultrusion, so there is no need to prepare a special mandrel, and furthermore, it can be used as a mandrel. It has been found that there is an advantage that there is no need to pull out the molded article from the mandrel after molding, and therefore, the molded article can be produced extremely efficiently and quickly without damage.
