PURPOSE:To obtain a thin fiber reinforced resin sheet excellent in uniform mechanical property by drawing the fiber reinforced resin sheet with a thermoplastic resin sheet. CONSTITUTION:A fiber reinforced resin sheet is drawn with a thermoplastic resin sheet. As the fiber used for the fiber reinforced resin sheet of raw material, the fiber for ordinary fiber reinforced resin is used. For the thermoplastic resin sheet, a sheet having two times or more drawing property in the drawing direction, is used. For instance, a sheet of high density polyethylene, low density polyethylene or polyethylene, etc., is suitable. The kind of the resin in the thermoplastic resin sheet and the thickness of the sheet are selected so that the tensile strength of the thermoplastic resin sheet is larger than that of the fiber reinforced resin sheet of raw material in the draw-working condition, i.e. drawing direction, draw ratio and drawing temperature. The resin for the fiber reinforced resin sheet should have a good adhesion with the thermoplastic resin sheet. |
