Pultrusion is a typical method for continuously obtaining fiber-reinforced plastic materials. In this molding method, fibers or pine materials impregnated with uncured resin are cured in a mold, and the shaped molded product is continuously taken off. Conventionally, there is no one that is straight in the direction and has a constant curvature.

The gist of the present invention is that in the thickness direction configuration in the direction in which curvature is desired, at least two types of fibers impregnated with resin and having different coefficients of linear expansion are glued together or run on a mandrel, and then pultruded. The object of the present invention is to continuously produce fiber-reinforced plastics having curvature in the longitudinal direction.
以下、図面に従つて本発明を説明する。 The present invention will be explained below with reference to the drawings.
