摘要： A system and method of reinforcing a portion of a pipe (30), including applying a fiber structure (12) to the portion of the pipe to be reinforced, and pressurizing.resin (41) through the fiber structure to the portion of the pipe to substantially saturate the fiber structure with resin, wherein the resin comprises a viscosity of less than about 10,000 cP and a surface tension of less than about 30 dynes. The resin is permitted to cure under ambient conditions at a peak exotherm of greater than about 200 OF, wherein the cured resin comprises a glass transition temperature of greater than about 150 OF and a heat distortion temperature of greater than about 150 OF. Pressurizing the resin may include use of a reinforcing containment (36) and underlying pliable mold (300) that is compressed to pressure the resin through the fiber structure to the pipe.
