PROBLEM TO BE SOLVED: To provide a reinforced sheet which includes a sheet material with a high elongation and a good tensile strength, and which has excellent processability and environmental characteristics, and a sheet-like structural material using the same. SOLUTION: The reinforced sheet which can be impregnated with an adhesive is obtained by paper-making a composition including a natural fiber, and has a plurality of linear cut parts provided approximately perpendicularly to the paper-making direction. Non-linear cut parts are preferably disposed so as to enclose one end or both ends of the linear cut parts respectively. Preferably, the non-linear cut part has its center resided on the linear cut part and is formed as an approximately arc having a central angle of not less than 120 degrees and not greater than 240 degrees. The composition preferably further includes a thermoplastic synthetic fiber and/or a non-thermoplastic chemical fiber. The disposed density of the linear cut parts is preferably not less than 10 parts/100 cm<SP POS="POST">2</SP>and not greater than 30 parts/100 cm<SP POS="POST">2</SP>. COPYRIGHT: (C)2012,JPO&INPIT |
