 Next, the armor of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration perspective view of a sheet-like material constituting the armor of the present invention. A honeycomb structure sheet in which a mesh structure knitted fabric is fixed with a resin and a large number of protrusions are formed by deep drawing The sheet-like material 1 is formed by polymerizing the cloth and / or plate-like material 3 on the front surface side of the material 2 and polymerizing the cloth and / or resin foam 4 on the back surface side.

FIG. 2 is a perspective view showing an example of a kendo armor, and FIG. 2 (1) shows a surface 5 and FIG. 2 (2) shows a body 6.

FIG. 3 is a perspective view illustrating a breast pad 7 for a baseball referee, and FIG. 4 is a perspective view illustrating a sports pad 8 for various sports.

The honeycomb structure sheet-like product of the present invention includes (1) for example, polyamide fiber, aromatic polyamide fiber, polyester fiber, wholly aromatic polyester fiber, polyvinyl alcohol fiber, acrylic fiber, cellulose acetate fiber, etc. Multifilament yarn or spun yarn having a total fineness of 200 to 5,000 denier mainly composed of synthetic fibers, inorganic fibers such as carbon fibers and glass fibers, and spun yarns are used, for example, tricot and ratcell. A warp knitting method, a weaving method such as a flat knitting method, a rubber knitting method, or a plain weaving method is used to make a woven cloth having a mesh structure with a mesh of 1 to 7 mm, and the woven cloth is made of a phenol. Resin selected from resin, melamine resin, epoxy resin, polyester resin, urethane resin, vinyl chloride resin, etc., preferably A sheet-like material on which 20 to 120% by weight of a thermosetting resin is adhered and fixed with respect to the weight of the textile fabric. (2) For example, 10 to 50% by weight of a high melting point fiber yarn having a breaking strength of 5 g / denier or more and a melting point of 200 ° C. or more and a low melting point synthetic fiber yarn at least 20 ° C. lower than the melting point of the high melting point fiber yarn. A fiber with a total fineness of 200 to 5,000 denier obtained by blending, blending or twisting, and making a mesh structure with a mesh size of 1 to 7 mm, and heat treating it to heat-deform the low melting point synthetic fiber. A sheet-shaped product in which a woven fabric is fixed with a material, or a sheet-like product in which a thermal deformation product of a fiber and a resin are fixed. (3) For example, a core-sheath type composite fiber or a joint type composite fiber comprising a high melting point synthetic resin component and a low melting point synthetic resin component lower than the melting point of the high melting point synthetic resin by at least 20 ° C., or A fiber yarn having a total fineness of 300 to 5,000 denier obtained by mixing, blending or twisting high melting point fibers having a melting point of at least 20 ° C higher than the melting point of the low melting point synthetic resin component and usually having an opening of 1 to 7 mm. It is a sheet-like product in which a mesh-structured woven fabric is prepared and heat-treated to fix the woven fabric with a thermal deformation product of the low melting point component of the composite fiber, or a thermal deformation product of the fiber and a resin-fixed sheet product.

The shape of this sheet-like material is appropriately determined depending on the purpose of use and size of the armor, but it is usually ³ to 20 mm in depth and 9 to 9 protrusions with an average cross-sectional area of 0.2 to 9.0 cm ^2. A sheet of honeycomb structure was formed by deep drawing to about 200 pieces / 100 cm ² . Furthermore, in order to impart high impact strength to the protrusion of the sheet, the compressive deformation strength required to deform 20% by compressing the projections of at least 20 Kg / cm ^2, preferably 30 Kg / cm ² or more I shall. For that purpose, the thickness of the fiber, the selection of the resin, the amount of adhesion, and the hardness are adjusted. If the compressive deformation strength is small, it is deformed or damaged by an external impact force, which is not preferable as an armor. The average cross-sectional area is the average value of the areas of the cross section of the middle part of the protrusion and the area of the aperture.

One or two sheets of the honeycomb structure sheet-like material are laminated to form a core material, and the fabric that is polymerized with the core material is a non-woven fabric of fibers selected from ordinary synthetic fibers, natural fibers or inorganic fibers, Examples thereof include knitted fabrics, woven fabrics, and the like, or composite fabrics of non-woven fabrics and woven fabrics, and resin foams are, for example, expanded polystyrene, expanded polyurethane, expanded polypropylene, expanded vinyl chloride resin, and the like. The material is, for example, a molded plate obtained by resin-processing an ordinary non-woven fabric or a composite fabric of a non-woven fabric and a woven fabric, a resin-molded plate, a bamboo / wood board. The selection, combination, and thickness of these materials are appropriately selected depending on the desired armor. The honeycomb structure sheet and the polymer are joined by a heat bonding method such as ultrasonic method or high frequency method, a bonding method using an adhesive, or a sewing method, so that the sheet shape is lightweight and has high compressive deformation strength and toughness. The thing is obtained. This sheet-like material is molded into a desired shape to form various kinds of armor.

Example 1 A polyester knitted fabric having a mesh opening of 3 mm was made by a Russell knitting method, and about 52% by weight of a melamine resin was applied to the mesh knitted fabric, and hot press molding was performed to form protrusions having a diameter of 8 mm and a depth. 100/100 cm ² applied the compressive deformation strength of the protrusion of 4mm was obtained honeycomb structure sheet of 22 Kg / cm ^2. A non-woven fabric and a woven fabric were polymerized on both sides of this sheet-like material and joined by a sewing method to form a base material sheet-like object, and then the whole structure except the facial grill was constructed as shown in FIG. 2 (1). This product weighs about 3/4 of the weight of the conventional product, and a kendo surface with less discomfort was obtained.

Example 2 As a sheet to be polymerized on the surface side of the honeycomb structure sheet-like material of Example 1, after applying a thermosetting polyester resin containing a colorant to a nonwoven fabric mixed with thermal binder fibers Using the sheet obtained by heat treatment, the non-woven fabric and the woven fabric were polymerized on the back side, and the whole was thermoformed by the high frequency method to make a kendo barrel as shown in Fig. 2 (2). The obtained product weighed about 2/3 of that of the conventional product, had a high impact resistance, and was obtained with a body with less stuffiness.
