PROBLEM TO BE SOLVED: To provide a method for producing a reinforcing base material for a composite material part even having a complicated curved surface while suppressing manufacturing costs and improving moldability and a composite material part.SOLUTION: The method for producing a reinforcing base material 6 used for a composite material part made of a fiber reinforced composite member, in which an aimed shape is an outline of the composite material part and which comprises: forming continuous loops 3 with a first reinforcing fiber yarn 2; knitting a knitted layer having a curved surface imitating the aimed shape by combining the continuous loops 3; and passing a second reinforcing fiber yarn 4 through the continuous loops 3 and interweaving it into the knitted layer to form a reinforced part.SELECTED DRAWING: Figure 4 【課題】複雑な曲面を有する複合材部品であっても、製造コストを抑制しつつ、成形性を向上させられる強化基材および複合材部品の製造方法を提供することを目的とする。【解決手段】本発明は、繊維強化複合材料製の複合材部品に用いられる強化基材６を製造する方法であって、前記複合材部品の輪郭を目的形状とし、第１の強化繊維糸２で連続的ループ３を作り、該連続的ループ３を組み合せて前記目的形状に倣った曲面を有する編物層を編成し、第２の強化繊維糸４を前記連続的ループ３に通して前記編物層に編み込んで強化部を形成する。【選択図】図４
