CONTINUOUS FIBER COMPOSITE MATERIAL STRUCTURE, METHOD FOR MANUFACTURING THE SAME, AND COMPOSITE MOLDED OBJECT USING THE CONTINUOUS FIBER COMPOSITE MATERIAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To precisely provide a continuous fiber composite material structure enhanced in strength and rigidity with high productivity.

SOLUTION: The continuous fiber composite material structure is composed of continuous fiber bundles arranged in a state substantially parallel to each other and thermoplastic resin and has a specific curvature. This structure contains parts having a curvature of 1/(20×d) (rad/mm), wherein d is the width (mm) of the structure in the direction crossing the orientation direction of continuous fibers at a right angle before bending is imparted, or above (A) and satisfying that the sum total of the center angles of the parts having the curvature of 1/(20×d) (rad/mm) or above is 30° or above (B) with respect to a skeletal line connecting the center parts in the width direction of the structure in the direction crossing the orientation direction of the continuous fiber bundles at a right angle without buckling the continuous fiber bundles.
