FRP pipes are widely used in watertank, hot springs, chemical plants, and wastes disposal plants. However, conventional methods of manufacturing FRP pipes have several problems, such as high cost, emission of organic gas during manufacturing, etc. To overcome such difficulties, anew manufacturing method is developed. In this new method, FRP pipe is manufactured by centrifugal force generated by revolving of the mold. In this study, mechanical properties of this new pipe is investigated through tensile tests and bending tests. Also, the structure of the FRP pipe is examined through a microscope, and the results are compared with the ones of conventional pipes. It is found that the tensile strength of new pipe is rather higher than that of conventional pipe.
