Abstract:
A manufacturing method of the present invention includes the steps of: winding a fiber reinforced resin member containing a fiber and a matrix resin around a mandrel to obtain an intermediate formed body; winding a wrapping tape around the intermediate formed body with an application of a tension; heating the intermediate formed body to cure the matrix resin; and pulling the mandrel out and removing the wrapping tape after the step of heating to obtain a cured tubular body. A base polymer of a base material of the wrapping tape is a polyolefin resin and/or a polyester resin. The step of heating includes: a first heating stage for heating the intermediate formed body at a temperature of 70° C. or higher and 90° C. or lower for a time of 120 minutes or longer and 4320 minutes or shorter; and a second heating stage for heating the intermediate formed body at a temperature of 120° C. or higher and 200° C. or lower for a time of 5 minutes or longer and 20 minutes or shorter after the first heating stage.
