摘要： PURPOSE: To prevent the decrease in strength in a bonded part without changing the thickness of the bonded part substantially from that of a non-bonded part by polymerizing a spot to be polymerized while transferring one divided bundle of fibers of lengths from the shortest to the longest to the other divided bundle of fibers of lengths from the longest to the shortest, the spot being transferred in sequence in the longitudinal direction of a reinforcing fiber bundle. CONSTITUTION: Surface coating materials 4 around the end parts of a pair of uncured fiber reinforced resin rod-shaped bodies A, B to be bonded are cut by 1m respectively, and the cut parts are peeled so that reinforcing fiber bundles 2 are exposed. Next, the exposed fiber bundles 2 of the end parts of the rod- shaped bodies A, B are divided nearly equally into divided fiber bundles a10, a9,...a2, a1 and b1, b2,...b9, b10, and the lengths of two bundles of the exposed parts are cut into five ranks from 1000mm to 200mm, respectively. Next, the length L of polymerization is made 200mm, and a10 and b10, a9 and b9, a8 and b8, a7 and b7, a4 and b4, a3 and b3, a2 and b2, a1 and b1 are transferred in sequence respectively in the longitudinal direction of the reinforcing fiber bundle 2 to be polymerized.
