Abstract
Description
【発明の詳細な説明】 本発明は繊維強化複合部材の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a fiber-reinforced composite member.

７−１７３６８７号参照）。The applicant previously applied a high-pressure solidification casting method as a manufacturing method for this type of molded material, and developed a fiber molded product by applying high hydrostatic pressure to the molten metal near at least one end of the rod-shaped fiber molded product. We have proposed a method of filling and compounding (patent application filed in 1973).

て未充填複合箇所を発生ずるおそれがある。The above-mentioned filling and compounding of the molten metal into the fiber molded body must be done efficiently in a short time because it is carried out when the molten metal reaches a semi-solidified state, but conventional fiber molded bodies do not bind long fibers together. Since it is formed into a solid shape, when pressurizing the vicinity of one end, even if the filling composite property is good in the longitudinal direction of the fiber molding, the filling composite property is not good in the direction perpendicular to the longitudinal direction of the fiber molding. The properties of the molten metal are not very good, and therefore the molten metal cannot efficiently fill the entire fiber molded body, and the molten metal may cool down within the fiber molded body, resulting in unfilled composite areas.
本発明は上記に鑑み、繊維成形体全体に対する溶湯の充
