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.

A method of manufacturing a fiber-reinforced resin pipe comprising the steps of: forming a plurality of layers by alternately winding a readily impregnated thin loose cloth-like material, in the form of a loose cloth having a thickness of 0.1 to 0.5 mm and a density of 20 to 100 g/m2, and a continuo

A method of manufacturing a fiber-reinforced resin pipe comprising the steps of: forming a plurality of layers by alternately winding a readily impregnated thin loose cloth-like material, in the form of a loose cloth having a thickness of 0.1 to 0.5 mm and a density of 20 to 100 g/m2, and a continuous fiber on a core; placing said core with said layers formed thereon within a split type outer mold having an inner surface which forms a desired outer surface of said pipe; injecting a liquid synthetic resin at a pressure in a range of 1 to 2 Kg force/cm2 between said outer mold and said core so that said liquid resin is integrated with said layers and cured into a molded product; and then removing said molded product from said outer mold and removing said core from said molded product.
