Internal distribution of residual strain in high-pressure composite vessel using high energy synchrotron radiation X-rays at BL22XU in SPrng-8 was carried out for evaluation of durability improvements. The specimen was high-pressure vessel made of aluminum with 170diameter mm × 500 length mm and the thickness 4mm. The strain scanning method was used to obtain each strain distribution of 3 directions. From the distributions by 311 diffraction of aluminum, it was found that the strains of axial and hoop direction were compression and that of radial direction was tensile. And it was clarified that these result almost agreed with residual strains which were expected to generate for high-pressure vessel rolled fiber.
