Abstract
A method of manufacturing a fiber-reinforced resin pipe which including the steps of forming a plurality of layers by alternately winding a cloth-like material and a continuous fiber on a core. Placing the core in a split type outer mold having an inner surface which forms a desired outer surface of the pipe. Injecting a liquid synthetic resin between the outer mold and the core so that the liquid resin is integrated with the layers and cured into a molded product. Removing the molded product from the outer mold after the resin has cured and removing the core form the molded product.
