| 摘要 |
There is provided a component part (1) made up of a tubular skeleton member (1B) that is formed by a structural material-purpose reaction injection molding of a thermoplastic resin reinforced by a continuous fiber and that is enhanced in rigid strength, and projection-and-depression structures (1A, 1C) that cover two end openings of the tubular skeleton member and that are made of a thermoplastic resin that is of the same family as and is highly compatible with the foregoing thermoplastic resin. In the production method for the component part (1), before the thermoplastic resin used in the structural material-purpose reaction injection molding finishes polymerizing, the thermoplastic resin is injected to a mold cavity that surrounds the tubular skeleton member (1B), so that the component part (1) having high rigid strength is efficiently produced. |
