A Field-Replaceable Composite Roll system (FRCR) consists of a complex composite cover and a unique mechanical mounting system, configured to allow the retrofit of existing silicone sleeved rolls, as well as manufacture new rolls, at substantially lower costs. The system of the present invention can be used for retrofitting existing dead-shaft or live-shaft rolls previously manufactured to use silicone sleeves, as well as fabricating new rolls in conjunction with the patented WINERTIA(R) brand tubing or conventional thin-walled tubing. The exemplary embodiment of the composite cover is fabricated of a filament wound tube bound together via a resin or the like having dielectric properties, the tube forming inner and outer walls, the inner wall coated with a conductive layer for receiving and conducting an electric current, the outer wall coated with a wear resistant layer (illustrated as ceramic coating), followed by a sealant layer. The composite cover is configured to slide over and envelope a roller body, and be anchored in place via mechanical mount formed of first and second expansion rings and associated compression bases.
