CarbonX™ PEI + CF [Aerospace] is made using Sabic Ultem™ 9085 PEI (polyether imide) and Toray Torayca™ T800 Aerospace-grade carbon fiber. Toray’s T800 aerospace-grade carbon fiber offers excellent strength and stiffness and couples excellently to Ultem™ 9085 – creating an outstanding material with excellent flammability, thermal, mechanical, and chemical resistance properties.
CarbonX™ CF PEI 9085 Aerospace is made using Sabic Ultem™ 9085 resin and 10% certified Toray T800 chopped carbon fiber. This custom formulation is an excellent printing aerospace-grade material specifically formulated for our aerospace clients.
Ultem™ 9085 is FAA-approved for FST applications (Flame/Smoke/Toxicity) and meets FAR 25.853 and OSU 65/65 standards. Toray T800 carbon fiber has a 5µm diameter (vs. 7µm for standard carbon fiber) and allows for more fibers per cc3 of material than when using standard carbon fiber. This allows for superior strength and stiffness while maintaining excellent dimensional stability and printability.
Benefits of Ultem™ PEI+CF [Aerospace] Include:
- High thermal properties, Tg of 186°C and an HDT of 165°C
- Inherent flame resistance due to Ultem™ 9085 base resin
- Improved stiffness and strength for structural applications
- Excellent dimensional stability – lower CTE, warp, and shrinkage vs unfilled grades
- Resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions

PEI+CF Ultem 9085 Applications
- Aerospace: The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of ULTEM PEI+CF makes it an excellent candidate for aerospace and aircraft applications. ULTEM offers low toxicity, smoke, and flame evolution. Ultem resins are found in applications such as personal service units, oxygen panels and components, ventilation system components, connectors, cable ducts, latches, hinges, food tray containers, door handles, and interior cladding parts.
- Automotive & Transportation: PEI+CF resins provide automotive manufacturers with a high-performance, chemically resistant, thermally-stable, cost-effective alternative to metal that is strong enough to replace steel in some applications yet light enough to replace aluminum in others. For applications like transmission components, throttle bodies, ignition components, sensors, and thermostat housings.
- Electronics: PEI+CF may be an excellent material choice for today’s demanding electrical applications, including connectors, MCB components like housings, shafts and levers, hard disk drive internals, FOUPs, BiTS, PCBs, MCCB internals, Plenum devices, LCD projector internals, fuel cell components, and many other applications.
Carbon Fiber FilamentWhat Is It?
Fibers 5-10 micrometers wide made of carbon. The fibers are aligned following the axis of the material. This, along with their physical makeup, are what gives this material its excellent properties.What Does It Do?
Carbon Fibers demonstrate a lot of desirable material properties:
- High stiffness
- High tensile strength
- High heat tolerance
- High chemical resistance
- Low weight
- Low thermal expansion
Reinforcing plastic with carbon fibers produces a 3D printing filament that exhibits the best properties of both the carbon fibers and the plastic of choice.
What Is It Good For?
Ideal for any applications which require lightweight and rigidity. Carbon fiber reinforced parts, designed to use less material and save weight, are extremely popular in aerospace, civil engineering, the military, and motorsports.
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues. Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
