  • Method of manufacturing laminated flexible bearings, in particular for engine nozzle joints
    Patent number: 5248361
    Abstract: To make a laminated flexible bearing constituted by rigid reinforcing layers made of composite material alternating with layers of rubber or elastomer, each reinforcing layer is formed by winding a resin preimpregnated thread directly on the underlying layer of rubber or elastomer. Advantageously, the flexible bearing is made by alternating layers formed by winding a resin pre-impregnated thread and layers formed of non-vulcanized rubber or elastomer, after which the resin is polymerized and the rubber or elastomer is vulcanized simultaneously.
