<p><P>PROBLEM TO BE SOLVED: To provide a layered structure of prepreg which can improve the bonding strength of prepregs. <P>SOLUTION: The prepreg layered structure 10 has a structure in which prepregs 2A and 2B are layered. A 0°fiber layer 3 in which reinforcement fibers are aligned in the load direction where a tensile load acts (referred to as a 0°direction) is formed on one side of a prepreg 2A. A 90°fiber layer 4 in which reinforcement fibers are aligned in the direction perpendicular to the load direction (referred to as a 90°direction) is formed on the other side of a prepreg 2. The prepreg layered structure 10 has a two-layer bonded structure in which the prepregs 2A and 2B are layered so that respective 0°fiber layers 3 in the prepregs 2A and 2B are bonded in a state where the prepregs 2A and 2B are mutually shifted in a plane direction (load direction). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
