Abstract
Cisterns or vats made by bending and edge bonding a flexible sheet of laminated reinforced resin to obtain a straight hollow body and then distorting that body to match the profile of at least one rigid prefabricated panel which forms a cap or bulkhead defining the cross-sectional shape of the vessel. The components are bonded together by curing then completed. The process is used for mfr. of reservoirs of maximum capacity w.r.t. some size location or access, e.g. a cave mouth. Initial lay-up as a flat sheet allows extra material thickness to be laid up in those zones which will be relatively highly stressed in the end use shape or position of the tank, unlike vessels produced with uniform or symmetrical wall thicknesses as unitary wound structures on mandrel lay-up equipment. Access holes, etc. may be generated before or after assembly.
