The invention involves fluorine plastic liner manufacturing and application technology, particularly a fluorine plastic lining composite product and its manufacturing method. Its characteristic is: it contains glass fibers, fluorinated ethylenepropylene copolymer and PTFE, they are coiled on stainless steel supporting mold consecutively, then the out surface is coiled with alkali-free glass fiberbelts, it is pressed and sintered in high-temperature and molten condition, fluorinated ethylenepropylene copolymer permeates into the glass fiber gap laid on surface, cooling out furnace, disassembling the alkali-free glass fiber belts and demolding, then the product is completed or is sheared into sheets. It aims at designing a fluorine plastic composite product which can process the fluorine plastic and metal components with lining on site and its production method. The invention fills the technology gap of large equipment can not process PTFE with lining, reduces a lot of costs of electricity, coal energy and transportation, greatly expands PTFE lining equipment application scope, and plays a positive role of replacing the products made by expensive rare metals materials.
