More Information
Summary:Provided is a pneumatic fender that can expand more greatly during use than when the pneumatic fender is not in use, such as when stored, transported, or the like, and that can correct distortion at or near a boundary between a body portion and each of hemispherical portions at both ends to expand an overall shape more similarly than in the related art. Reinforcing layers (3) of a body portion (2) and reinforcing layers (5) of a predetermined range (4A) in the longitudinal direction of a fender near a boundary between each hemispherical portion (4) and the body portion (2) are formed by aligning a number of cords (3a, 3b) and cords (5a, 5b) in parallel, and in a neutral state without expansion, the cords (3a, 3b) of the reinforcing layers (3) layered adjacent to each other meet each other and the cords (5a, 5b) of the reinforcing layers (5) layered adjacent to each other meet each other, and cord angles A and B are each set to from 15° to 45° with respect to the longitudinal direction of the fender. When the interior of the fender 1 is filled with air to be set to a specified internal pressure, the cord angles A and B increase to the extent of a static angle, and the body portion (2) and the predetermined range (4A) of each hemispherical portion (4) are greatly enlarged in diameter and expand.
