Abstract: A method of manufacturing a reinforcing fiber sheet includes the following steps (a) to (c). In the first step, a screen having a mesh size which is coarser than a standard mesh size is set on top of a cloth layer constructed of vertically and horizontally woven vertical strips and horizontal strips which are assemblages of numerous reinforcing fibers. In the second step, an ink that exhibits good flexibility after drying is supplied onto the screen in a screen printing, and the cloth layer is impregnated with the ink. In the third step, the cloth layer impregnated with the ink is dried to form a cloth core. This cloth core is embedded in a matrix resin and used as a reinforcing material for a molded article, or a synthetic resin high-stretch sheet material and the resulting assembly is used as a material for dress-up sheets.

Abstract: The reinforcing fiber sheet of the present invention has a cloth core 4 that includes a cloth layer 13 constructed of vertically and horizontally woven vertical strips 11 and horizontal strips 12 which are assemblages of numerous reinforcing fibers, and a binding and reinforcing layer 14 impregnated into the cloth layer 13 so as to allow the cloth layer 13 to deform at ordinary room temperature with the vertical strips 11 and horizontal strips 12 remaining in a mutually bonded state. This cloth core 4 is embedded in a matrix resin and used in this way as a reinforcing material for molded articles, or a synthetic resin high-stretch sheet material that is transparent and has good stretch is permanently bonded to the cloth core 4 and the resulting assembly is used as a material for dress-up sheets.

Abstract: High stretchable sheet material according to the invention is adapted to maintain the flexibility of an ink applied to a base over an extended period of time, so that the sheet material may be even stuck on a curved portion, which increases the stretch ratio of the base, without suffering the degradation of the color or glossy appearance thereof. The high stretchable sheet material of the invention is arranged such that a binding/reinforcing layer (3) is formed on a back side of a base (2) formed of a synthetic resin sheet by impregnating a binder into the base (2), the binder including an ink (11) exhibiting a high flexibility in a dry state, and that a back side of the binding/reinforcing layer (3) is covered by an adhesive layer (6) and a separator sheet (7) adhered to a back side of the adhesive layer.
