摘要：A method of constructing a collapsible mandrel for use in fabricating filamentwound vessels or tanks includes the steps of preparing a rigid mandrel and supportingthe mandrel on a rotatable axle, applying one or more layers of strips of rubberlongitudinally on the mandrel to form an enclosure, applying coats of rubber solutionover the layers, winding a layer of fibers over at least one of the layers, and curing therubber layers. The layers are cut into two parts, removed from the rigid mandrel, andrejoined by using reinforcing straps along the seam of the joined parts. The collapsiblemandrel may be used to fabricate either filament wound tanks or other collapsiblemandrels, neither of which would have a seam or joint since, after constructing the tankor second mandrel on the first inflated collapsible mandrel, the first mandrel would bedeflated, collapsed and removed from the interior of the tank or second mandrel. Thiswould leave a tank or second mandrel with continuous, unbroken layers forming theshell.
