Method and apparatus for making filament reinforced storage vessels
Abstract
Abstract A FIBERGLASS REINFORCED STORAGE TANK FORMED BY CONSTRUCTING A FILAMENT REINFORCED CYLINDRICAL SIDE WALL AND ENCLOSING THE TRANSVERSE ENDS WITH A PAIR OF END DOMES. THE EMD DOMES ARE PREFRABICATED IN A CIRCULAR MOLD OF PROPER CONTOUR AND SIZE. A SOLVENT DISPERSED MOLD RELEASE AGENT IS SPRAYED INTO THE MOLD OVER THE ENTIRE MOLD SURFACE. GLASS FILAMENTS ARE THEN LAID ALONG WITH A SPRAY OF CATALYZED BINDER RESIN IN THE ROTATING HEATED MOLD, BEGINNING AT THE CENTER AND EXTENDING TO THE OUTER PERIPHERY THEREOF TO FORM THE RESIN CURED RIGID END DOMES. THE ANNULAR CYCLINDRICAL SIDE WALL IS FORMED BY APPLYING FIBERGLASS RESIN TO THE INTERIOR SURFACE OF A ROTATION CYLINDRICAL MOLD IN THE PRESENCE OF A CATALYZED BINDER RESIN WITH THE FORMED END DOMES SECURED TO THE TRANSVERSE ENDS OF THE MOLD DURING SIDE WALL FORMATION. A PARTICULATE MATTER SUCH AS SAND MAY BE ADDED TO THE COMPOSITION. THE MOLD IS DIVIDED INTO LONGITUDINAL ARCUATE SECTIONS WHICH ARE CAPABLE OF SEPARATING FOR REMOVAL OF A FINALLY FORMED STORAGE TANK.
