PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material which can be manufactured at low cost. SOLUTION: An x thread layer and a y thread layer formed by arranging continuous fibers in one direction are laminated alternately in plural layers to form a laminated fiber group 6 of biaxial orientation. A fiber structure 1 is provided with a non cut-off domain 2 and a cut-off domain 3; wherein the continuous fiber of the laminated fiber group 6, combined by a thickness direction thread 7 and a fall-off preventing thread 8, of the non cut-off domain 2 is not cut off, while the continuous fiber of the cut-off domain 3 is cut off. The cut-off domain 3 is provided in a part where a deformation is required on shaping into product shape. Also, both end parts of the fiber structure 1 serve as the non cut-off domain 2. The cut-off domain 3 is easy to deform due to weak binding since a portion of the threads is cut off. Therefore, deformation on shaping is easy even if the continuous fiber in three dimensional fiber structure is used as a reinforcement. COPYRIGHT: (C)2008,JPO&INPIT |
