And it is commonly used. Furthermore, in recent years, in order to achieve weight reduction of bulletproof shields and bulletproof helmets, an aramid fiber reinforced composite material plate (Japanese Patent Laid-Open No. 61-101799) or a high-strength polyethylene fiber reinforced composite material plate which is an invention of one of the applicants of the present invention. There are inventions such as the bulletproof article used (JP-A-60-178296). However, although the metal plate is excellent in durability and rigidity, there is a problem that it becomes too heavy to satisfy necessary bullet resistance. Therefore, in order to reduce the weight of bulletproof shields and bulletproof helmets, bulletproof shields and bulletproof helmets using the above-mentioned high-strength fiber-reinforced composite material have appeared, but these are superior to metal plates in terms of weight reduction, but during use It is easily scratched, has a problem in durability, and is inferior to a metal plate in terms of flameproofness.

望ましい。Here, the UD sheet is a sheet in which fibers in a woven or knitted fabric are orthogonally arranged at 0 ° and 90 ° and impregnated with a resin, and the woven or knitted fabric having the highest strength utilization rate of the yarn. It is in the form of. The light-weight, impact-resistant member of the present invention has a sheet-like material obtained by impregnating a cloth made of high-strength polyethylene fiber with a synthetic resin, and has a high-strength, high-elasticity polyethylene fiber with a single yarn denier of 1d to 10d. Resin-impregnated UD sheets, which are arranged orthogonally in the directions of 90 ° and 90 °, are laminated and formed so as to be 30% by weight or more with respect to the weight of the fiber-reinforced composite material, and at least the composite material It is desirable to join a metal plate having a thickness of 5 to 30% of the total thickness on one surface.

ができない。The high-strength, high-elasticity polyethylene filament yarn used in the present invention has a tensile strength of 20 g / d or more, preferably 30 g / d or more, and a tensile elastic modulus of 500 g / d or more, preferably 800 g / d or more. Is. When the tensile strength of the polyethylene filament yarn is less than 20 g / d and the tensile elastic modulus is less than 500 g / d, sufficient fabric strength and elastic modulus cannot be obtained, so that the impact energy-absorbing effect of the fabric is reduced. As a result, in order to obtain the required impact resistance properties, it is necessary to significantly increase the number of laminated fabrics, resulting in an increase in weight, and it is not possible to achieve the weight reduction as the object of the present invention.

レグを５０重量％以下になるよう複合積層してもよい。Further, if the ratio of the UD sheet to the weight of the above composite material is less than 30% by weight, the impact energy absorption amount per unit weight becomes insufficient, so that satisfactory impact resistance performance cannot be obtained. However, if the UD sheets are laminated so that the ratio of the UD sheet to the weight of the laminated plate is 30% by weight or more, preferably 70% by weight or more, excellent impact resistance per unit weight can be secured. When the fabric is used, the yarn having the highest tenacity factor is the use of the UD sheet. Therefore, in the present invention, the UD sheet is specified. In this case, a woven fabric using high-strength and high-elasticity polyethylene fibers combined with a UD sheet may be composite-laminated with a resin-impregnated prepreg of 50% by weight or less.

m 2 , preferably 80 to 110 g / m 2 , the content of synthetic resin impregnated is 15 to 45% by weight, preferably 25 to 40% by weight
Then, by stacking a large number of sheet-like materials as the composite material, the highest impact resistance can be secured. Furthermore, if a metal plate is bonded to at least one surface of the fiber-reinforced composite material, the warhead will be deformed when the bullet collides, the penetration resistance will be improved, and the surface will not be easily scratched even after repeated use. It has the advantage of greatly improving the durability of the bulletproof helmet. Generally, as the metal plate, metal aluminum, aluminum alloy, or titanium alloy is preferably used in terms of workability and light weight. If the thickness of the metal plate is less than 2% of the total thickness of the laminated plate, the effect of collapsing the warhead is poor, and if it is 10% or more, the weight of the metal plate becomes heavy and the weight of the bulletproof shield or bulletproof helmet is satisfied. It is inappropriate because it is not done.
