熱加圧硬化してヘルメットとしたものである。FRP helmets have been used to protect the head. Conventional FRP helmets use glass fibers (chopped strand pine 1~, glass cloth, or a mixture thereof) as reinforcing fibers, which are impregnated with unsaturated polyester resin, then laminated, molded, and heated and pressed. It was hardened and made into a helmet.

くなるなどの問題点があった。However, in such conventional FRP helmets, the resin content of FRP is 60 to 95% by weight, which results in poor bullet resistance, and the specific gravity is high at 1.8 to 2.0, making it heavy. there were.
この発明は上記のような従来の問題点を解決するための

量％とする。The reinforcing fibers used in the present invention are aramid fibers, unlike conventional glass fibers, and among them, cloth with a high density and a weight per unit area of 451 to 471 g/m2 is used. Further, the resin used in the present invention is an unsaturated polyester resin, and the resin content is smaller than conventional resins, and is 15 to 20% by weight of the total.

溶媒に溶解して含浸させ、加熱して溶媒を気化させると
ともに、半硬化させてＢステージのプリプレグとする。If the resin content is small like this, if you impregnate it as is, the resin will clump in one place and will not spread throughout the area, so in order to uniformly impregnate the entire area, dissolve the resin in a solvent such as acetone and impregnate it. The material is heated to vaporize the solvent and semi-cured to form a B-stage prepreg.

It is cured to produce an FRP helmet. At this time, the bending strength ab of the product is 2-10 kg.

による損傷は少ない。The lightweight FRP helmet of the present invention is worn on the head and protects the head in the same way as the conventional FRP helmet. Since the lightweight FRP helmet of this invention has a low resin content, the resin does not completely fill the gaps between the reinforcing fibers, and the reinforcing fibers are in point contact to form a mesh structure, making it lightweight with a specific gravity of 1.5. . As a result, the load on the head is small, allowing users to exercise freely for long periods of time with little fatigue. In addition, since it has a mesh structure, the impact propagates one after another, making it highly resistant to bullets and less likely to be damaged by impact from bullets or the like.
