Description of the Related Art In recent years, with the development of industrial technology, a material having a plurality of functions that cannot be realized by a single material, for example, two types of materials having different characteristics have been highly improved by being compounded. The demand for composite materials has increased. In order to composite these two different materials, a composite material can be manufactured by applying a blending method or the like. By the way, the required properties for composite materials are becoming more complicated,
For example, a first member made of a polyimide resin having excellent mechanical properties and heat resistance is combined with a second member made of a tetrafluoroethylene / pafluoroalkoxyethylene resin having a small friction coefficient and excellent wear resistance. It is also required to do something. However, the melting temperature of the tetrafluoroethylene / pafluoroalkoxyethylene resin is lower than the melting temperature of the polyimide resin, and during the process of fusing the polyimide resin, the tetrafluoroethylene / pafluoroalkoxyethylene resin melts and flows out. Therefore, the shape of the product cannot be maintained, and it is very difficult to obtain the desired material properties.
