Unfilled FEP has low mechanical strength, low wear resistance, and high thermal expansion coefficient, which limits its application. FEP-based blends are ideal for injection or compression molding applications that require high temperature resistance, abrasion resistance, low friction, excellent chemical resistance, and toughness.
Properties
- Carbon fiber-loaded polymer composites have both high strength and low fatigue characteristics, and are lighter than most metals and alloys, and are widely used in the automotive and aerospace industries.
- It is well known that the mechanical response of carbon fiber-based composites will change significantly with changes in composition, including fiber content, porosity, type of epoxy adhesive and polymer-filler adhesion, as well as other microstructure details.

- Compared with pure resin, adding carbon fiber to FEP resin can reduce the surface resistivity, thereby dissipating static charges generated by surface-to-surface contact in rotating or moving equipment.
- In addition, the most important contribution of fillers and reinforcing materials to fluoropolymers is their influence on friction (friction and wear) properties.
Potential application areas of fiber-reinforced fluoropolymer composites
- Electronics and electrical industry (wiring, laminate, film)
- Aerospace industry (wiring of composite parts, release board)
- Automobiles (molded parts, fuel hoses, special wires, fuel cells)
