Abstract
The invention relates to composite sleeves for producing a cured in place pipe, to materials and methods for producing the composite sleeve, to methods for repairing a native pipe with the composite sleeve, and to improved cured in place pipes. The composite sleeve has multiple layers including a core layer of a curable one-part resin composition. The curable one-part resin composition is a solid material at 25° C. Preferably the resin composition is pliable at 25° C. so that it can be flexed during manufacturing and/or during installation in a native pipe.
