Abstract
A pipe is wrapped with a composite to form a pre-stressed interface to facilitate load sharing between the materials. Prior to being wrapped, the pipe is placed in tension via hydraulic devices or the like. Alternatively, a combination of cured and uncured composite wraps is used in proximity to each other to apply compressive stress to the pipe. In addition, the pipe may be subjected to cold temperatures to change its dimensions prior to being wrapped with a composite material.
