[Structure of shelter body 1 and hatch 2]
Although the shelter body 1 and the hatch 2 are formed of reinforced plastic, it is desirable to have the following three-layer structure so as to withstand an impact such as a disaster. The shelter body 1 may have the following laminated structure, and the hatch 2 may have a structure different from the three-layer laminated structure.
Further, the shelter body 1 and the hatch 2 may be formed of one layer of the following fiber-based reinforcing material, or may be formed of two layers of the following fiber-based reinforcing material and a foam or core material. In a two-layer structure, the fiber reinforcement is on the outside and the foam or core material is on the inside.

  The laminated structure (this laminated structure) of the shelter body 1 or the hatch 2 is obtained by sandwiching a foam or a core material between a first fiber-based reinforcing material and a second fiber-based reinforcing material and bonding them with a resin. In addition, hard urethane, polystyrene, polyethylene, or polypropylene is used as the foam, paper honeycomb, aluminum honeycomb, or the like is used as the core material, and glass fiber, carbon fiber, aramid fiber, basalt fiber, or biomass is used as the fiber reinforcement. Using fibers, etc., and unsaturated polyesters, vinyl esters, epoxies, phenols, polyimides, biomass, etc. as resins, and manufactured by L-RTM (Light-Resin Transfer Molding) forming method or infusion forming method. Because of its simple structure, it has enough strength to be used as an evacuation shelter. It can be a structure.

This laminated structure will be specifically described.
This laminated structure is a sandwich structure (laminated structure) in which a foam or core material (such as a foam) is sandwiched between a first reinforcing material and a second reinforcing material and joined together by a resin. is there.

  As the first and second reinforcing materials, fiber-based reinforcing materials such as glass fibers, carbon fibers, aramid fibers, basalt (basalt) fibers, or biomass fibers (natural fibers such as hemp and bamboo) are used. In particular, the basalt fiber is an environment-friendly high-strength fiber melt-spun from basalt, and has excellent tensile strength, heat resistance, ultraviolet resistance, acid resistance / alkali resistance, and strength comparable to an aramid fiber.

As foams such as foams, hard urethane, polystyrene foam, polyethylene, polypropylene, or the like is used.
As the core material such as foam, a paper honeycomb, an aluminum honeycomb or the like is used.
As the resin, unsaturated polyester, vinyl ester, epoxy, phenol, polyimide, biomass, or the like is used.

This laminated structure is manufactured using an L-RTM molding method or an infusion molding method.
