This article covers applications of PTFE high-temperature fabric in carbon fiber flat composite products. Compression molding: placed between molds and prepregs preventing epoxy resin adhesion, enabling easy demolding; sandwiched between multiple thin panels to avoid mutual adhesion. Vacuum bag molding: reusable release film between prepreg and breather cloth, allowing gas/resin passage while enabling easy peeling after cure; textured side transfers fine surface texture to improve bonding roughness, eliminating sanding. Continuous production: seamless non-stick conveyor belts carry prepregs through heating/pressing zones; cushion layer distributes pressure evenly reducing localized indentations.
