<p>PROBLEM TO BE SOLVED: To prevent the occurrence of a slip by a method wherein after the surface of a pipe formed of uncured thermal curable resin prepreg is coated with an antibacterial agent, thermal curable resin is cured and treated, a specified difference in level is formed in the longitudinal direction of a pipe surface. SOLUTION: A substance wherein two one-way prepregs formed of reinforcing fibers and epoxy resin are laminated such that prepreg fiber directions are extended at right angles with each other is wound around a mandrel made of iron three times. Further, the surface of prepreg formed of thermal curable resin wound around the mandrel formed of iron is spray-coated with an anti-bacterial water solution and after a tape is wound therearound and placed in a curing furnace to effect curing, the tape is removed. A handrail having 10-700μm differences in level formed in the longitudinal direction of a pipe surface at internals of a distance of 1-50 mm is molded. This constitution reduces the generation of cold and static electricity without mounting a cover, and simply manufactures a handrail having anti-bacterial operation.</p> |
