摘要： PURPOSE:To lighten weight, to increase strength and to improve shock resistance by laminating fiber-reinforced resin boards on both surfaces of a light-metallic hollow-shaped structural plate and using ultra-high strength polyethylene as the resin board on at least one surface. CONSTITUTION:A prepreg sheet, in which a matrix resin is impregnated with reinforcing fibers, is laminated on an aluminum hollow-shaped structure 2 by a filmy adhesive material 3. One layer or more of fiber-reinforced resin boards 1 using ultra-high strength polyethylene fibers are laminated on at least one surface of the aluminum hollow-shaped structural plate 2 as reinforcing fibers in the laminated sheet. At least two sheets are superposed alternately so as to be crossed at right angles in the fibrous direction in the lamination.

摘要： PURPOSE:To obtain an inexpensive, lightweight helmet excellent in penetration resistance and shock absorptivity and having high protective effect by reinforcing the outer ply with glass fiber layer and also reinforcing the inner ply with high-strength, high-modulus polyethylene fiber cloth layer. CONSTITUTION:The objective helmet consisting mainly of glass fiber-reinforced thermosetting resin. For the region falling within the range of making the shock absorptivity test specified by at least the JIS T 8133 (1982), the outer ply is reinforced with glass fiber layer 3 and the inner ply with high-strength, high- modulus polyethylene fiber cloth layer 4. It is preferable that said polyethylene fiber cloth be prepared by making satin woven cloths >=25g/de in tenacity and >=1000g/de in tensile modulus into a laminate 200-1000g/m in weight.

摘要： PURPOSE:To obtain a high strength, highly elastic and see-through laminate excellent in light resistance and water resistance by a structure wherein knitted and woven goods, a part of the warps and/or woofs of which consist of ultra high-strength polyethylene long fibers and the remaining part of which mainly consists of polyester fibers, are employed as base fabric, to which a biaxially oriented polyester film is laminated. CONSTITUTION:The warp and woof constituting a base fabric are ultra high- strength polyethylene long fiber thread and/or polyester fiber thread. At least on one side of the base fabric, which is produced by knitting or weaving said warps and woofs, a biaxially oriented film is bonded and laminated. The preferable unit degree of fineness of the thread constituting the warp and/or woof is 0.5-20 denier. Further, preferable warp and/or woof is substantially nontwisted and has the tensile strength of 15g/denier or higher and the total denier of 50-800 denier. The preferable weight per area of the basic fabric is 20-250g/m . The proper thickness of the biaxially oriented film is 12-125mum.

摘要： PURPOSE:To obtain an inexpensive optical fiber cord having high quality by placing longitudinally PE fibers around an optical fiber core in parallel in the longitudinal direction thereof without twisting and welding and uniting at least the outside peripheral part of the PE fibers with a specific org. high-polymer compd. CONSTITUTION:The PE fibers (A) has the tensile strength of at least 20g/denier, more preferably >=30g/denier and the tensile modulus of at least 500g/denier, more preferably >=800g/denier. The org. high-polymer compd. (C) has =2 kinds of mixed components are preferably for said compd. particularly to weld and unite the same to the outside peripheral part of the PE fibers (A). The better result is obtd. in terms of the reduction in the weight and diameter of the optical fiber cord as the tensile break strength of the wire-shaped composite body constituted by welding and uniting the (A) and (C) to be used is higher. A measure of such strength is at least 40kg/mm , more preferably >=60kg/mm .
