ABSTRACT:
A repair kit comprising fiber reinforced patching material impregnated with an ultra-violet light activated resin contained in a sealed package. In the preferred embodiment, the patching materials include a first piece of fiber reinforced material having randomly arranged fiber filaments or strands (i.e. a mat), and a second piece of fiber reinforced material having uniformly oriented fiber filaments (i.e. a cloth or roving). The impregnated first and second pieces of fiber reinforced material form a substantially inseparable, unitary patch when impregnated with the resin. The patch may also comprise a fiber reinforced mat and any variety of fiber reinforced cloth or roving attached thereto to form a single piece of fiber reinforced material such that the fiber filaments on one side of the patch are randomly arranged and the fiber filaments on the opposing side are uniformly oriented. The package containing the impregnated patching materials comprises oppositely disposed layers sealed together along a periphery to form a pocket for containing the patch and the resin. The package is impervious to ultra-violet light and chemicals to prevent exposure of the resin to ultra-violet light and to preserve the efficacy of the resin, respectively. The kit includes a paddle attached to the package for smoothing the patching materials to the area being repaired. An alternate embodiment of the kit may include protective gloves for preventing direct contact of the resin to the skin.
