TESTABLE COMPOSITE SYSTEMS FOR THE REINFORCEMENT OF METALLIC STRUCTURES FOR CONTAINING FLUIDS

摘要

A composite system for reinforcing a section of a curved metallic structure configured to contain fluids comprises a fabric carrier configured to be saturated with a uniformly dispersed reactive precursor. The reactive precursor chemically configured to activate and harden after removal of the reactive precursor from a protective packaging. The reactive precursor includes a radiopaque substance within a range of about 3 percent to about 50 percent by weight of the reactive precursor. The fabric carrier is adapted to be applied in overlapping layers to a surface of a curved metallic structure.

主权项

1. A repair kit for the reinforcement of a section of a curved metallic structure for containing fluids, the repair kit comprising:
a moisture impervious bag; and a woven fabric carrier including a continuous reinforcing fiber, the woven fabric carrier being pre-impregnated with a uniformly dispersed polyurethane resin reactive precursor, the woven fabric carrier being sealed in the moisture impervious bag isolating the reactive precursor from premature chemical activation, the reactive precursor chemically configured to activate and harden after removal of the woven fabric carrier from the moisture-impervious bag; wherein the reactive precursor includes a radiopaque substance within a range of about 3 percent to about 15 percent by weight of the reactive precursor, the reactive precursor uniformly dispersed within the woven fabric carrier, the radiopaque substance being suspended within the reactive precursor, the woven fabric carrier adapted to be applied to a curved metallic structure in overlapping layers of the fabric carrier.
