HEAT SHRINK LAMINATED COMPOSITE PATCH FOR REPAIRING COMPOSITE COMPONENTS

摘要

A sheet of heat shrink laminated composite for use creating repair patches for repairing or building up a surface formed of a composite material such as fiberglass-reinforced plastic. The sheet includes first and second layers of a heat-curable adhesive. The sheet includes a reinforcement layer sandwiched between the first and second layers of the adhesive. The sheet further includes a pressure application layer, which is formed of a heat-activated shrink wrap film, abutting an outer surface of the first layer of the adhesive. The reinforcement layer may include a sheet of a porous fabric or cloth, which may be fibers of carbon or glass such as unidirectional e-glass fibers. The adhesive is cured when heated to a temperature in a curing temperature range, and the shrink wrap film is activated when heated to a temperature in an activation temperature range that overlaps the curing temperature range of the adhesive.
