Abstract
Continuous rod-like molding having a FRP core and an outer skin of thermoplastic resin is shaped by introducing the molding into a passage of a heated die, the passage having a diameter slightly smaller at an exit thereof than an initial diameter of the molding, plasticizing the thermoplastic resin by passing the molding through the passage, thereby removing a part of the outer skin, and solidifying the thermoplastic resin, thereby obtaining a product having a diameter equal to the diameter of the exit of the passage.
