... to provide clamping pressure for the wet, ambient-temperature cure adhesive. Many other methods to produce mast tubes have been tested and, in some cases, developed to commercial level for specific size-range products. These include wet lay-up over tapered mandrels, bladder molding of prepregs for small...

.... The sleeve can then be removed from the mandrel, with the uncured tube in place. The tube and rubber liner are then placed in a closed mold and the bladder is inflated during the cure. This method is particularly useful for fabricating irregularly shaped tubes. For round tubes, the mandrel can be left...
