- 7. A tubular molded body according to claim 6, wherein said at least one layer including the resin bonded to said at least one film is an unreinforced resin layer.
- 8. A tubular molded body according to claim 1, wherein the at least one film bonded to the at least one layer including a resin is laminated and adhesively bonded to an inside surface of at least one fiber-reinforced resin layer, said at least one layer and film and said at least one fiber reinforced layer being laminated and adhesively bonded to one another.
- 9. A tubular molded body according to claim 8, wherein said at least one layer including the resin bonding to said at least one film is an unreinforced resin layer.
- 10. A tubular molded body according to claim 1, wherein the at least one film bonded to the at Least one layer including a resin is laminated and adhesively bonded to an outside surface and an inside surface of at least one fiber-reinforced resin layer, said at least one layer and film and said at least one fiber reinforced layer being laminated and adhesively bonded to one another.
- 11. A tubular molded body according to claim 10, wherein said at least one layer including the resin bonded to said at least one film is an unreinforced resin layer.
- 12. A tubular molded body according to claim 1, wherein a resin used in said at least one layer including the resin is a thermosetting layer.
- 13. A tubular molded body according to claim 12, wherein the thermosetting resin is a resin selected from the group consisting of an epoxy resin, a polyimide resin, an unsaturated polyester resin, a phenolic resin and a polyurethane resin.
- 14. A tubular molded body according to claim 1, wherein a resin used in said at least one layer including the resin is a thermoplastic layer.
- 15. A tubular molded body according to claim 14, wherein the thermoplastic resin is a resin selected from the group consisting of a polyphenylene sulfide, a polyether ketone, a polyether ether ketone, a polyether sulfone, a polyether imide and a polyamide imide.
- 16. A tubular molded body according to claim 4, wherein the fiber-reinforced layer is reinforced by a fiber selected from the group consisting of carbon fiber, glass fiber, aromatic polyamide fiber, boron fiber, alumina fiber, silicon carbide fiber, polybenzimidazole fiber and polybenzothiazole fiber.
- 17. A tubular molded body according to claim 4, wherein the reinforcing fibers in the fiber-reinforced resin layer consist of a unidirectionally fiber-arranged sheet.
- 18. A tubular molded body according to claim 4, wherein the fiber-reinforced resin layer comprises a sheet of reinforcing fibers, said sheet being selected from the group consisting of a woven fabric, a knitted fabric, a nonwoven fabric and a matted sheet.
- 19. A method of manufacturing a tubular molded bold, wherein at least one layer of a film comprised of an aromatic polyamide having substantially no melting point and having a tensile modulus of 700 kg/mm.sup.2 or more and a tensile strength of 35 kg/mm.sup.2 or more and having a thickness between 2 and 100 micrometers and at least one layer of a fiber-reinforced resin layer are wound and laminated to form a tubular molded body, the tension applied to the film at the time of winding the film being 8 kg/mm.sup.2 or more.
- 20. A method of manufacturing a tubular molded body according to claim 19, wherein the resin used in the fiber-reinforced layer is a thermosetting resin.
