Abstract
Conventional ship launching airbags are made of several layers of rubber and fiber meshes bonded together by vulcanization. With the existing fabrication process, an airbag is strong in standing heavy pressure at its surfaces, but weak against the cutting by sharp edges of metal debris or oyster shells. An airbag's functional failure during a field operation can cause not only stoppage, but also explosion, hence a serious safety hazard. To overcome such structural weakness, a new type of airbags with anti-cutting capability is disclosed in which a conventional ship launching airbag is covered with a layer of anti-cutting armor made of steel cord ply sheets, a standard off-the-shelf product for the making of tires, embedded at the surface of the airbag's main body.
