ABSTRACT:
In forming a reinforced fitting, an inner shell is first formed of alternate layers of glass filaments arranged transversely and parallel to the central axis of the tubular fitting portion of which comprising a part; the filaments are embedded in a matrix of cured resin such as epoxy resin. A rigid reinforcing metal cage is welded over the inner shell and a curable resin paste is applied to the outer surface of the cage so as to fill in all interstices between the cage and inner shell as well as interstices between the cage portions so as to form a substantially smooth outer surface in the partially-formed body with no voids therein. Additional resin-saturated glass filaments are then disposed over the smooth shell outer surface in a substantially uniform manner to provide a fitting construction of desired dimensions. The final fitting of desired dimensions is then subjected to desired curing procedures to assure desired resin hardening without effecting separation of the metal cage from the glass-resin matrix.
In the course of forming the inner shell, female threads may be integrally formed on at least one tubular end portion. The resulting reinforced fitting construction is of great strength; being resistant to great internal pressures, external collapse forces, tensile, shear and torsion forces.
