PURPOSE: To provide a method of manufacturing, without the need of special facilities, a fiber reinforced thermoplastic resin sheet of being bent spontaneously and the most suitable for use in the material of a fiber reinforced resin cylinder.
CONSTITUTION: In the case of laminating two or more fiber layers and making an integrated sheet by impregnating a thermoplastic resin sheet to be a matrix thereto, there is provided an anisotropy in the direction of thickness by making a difference in the material and/or constitution of a lamination-fiber layer, and then heat-processing is effected to the one where at least one layer of the fiber layers is made a layer of being intersectionally arranged with long fibers under the existence of thermoplastic resin, thereby obtaining a curved sheet.
