DescriptionCFC Smooth RodsTemperature Rating:In vacuum – 5432℉ | 3000℃Grade: Smooth PC70Benefits of CFC Smooth Rods High strength and modulus. Fire-resistant and dimensionally stable. Configuration of Carbon Fabric. Fatigue and fracture resistant. Cracks will not propagate as with molded graphite fixtures. Lightweight and low thermal mass permitting one to load more parts in each furnace due to the material’s excellent strength to weight ratio while reducing cycle time. Thermal deformation-resistant. CFC will remain flat and increase in strength at elevated temperatures reducing scrap and maintaining stricter part tolerances in comparison to a metal that warps over time.Applications of CFC Smooth Rods Aerospace and military Heat treating and furnace fixtures Primary and secondary structures Windmill blades Brake linings, automotive, and tooling Solid rocket nozzlesPropertiesTypical PropertiesUnitsPC70PC70HWL60IC50Fiber Direction / LengthRandom / ShortRandom / ShortUnidirectional 0° / 90° / LongRandom / ShortBulk Densityg/cm³1.71.7 1.61.5Flexural StrengthMPa200200 100100Tensile StrengthMPa120145200N/AYoungs ModulusGPa455065N/ACompressive StrengthMPa120200 N/AN/AInterlaminar Shear StrengthMPa1919 1110(Room Temp‑1300℃) Coefficient of Thermal Expansion∥ ⊥10 -6/℃ 10 -6/℃1.3 10TBA TBA1.1 91.1 9Thermal Conductivity∥ ⊥W/m · k35 1235 1233 1035 12Specific Heat20℃J/Kg · K720720TBA720Electrical ResistivityμΩcm2800TBA2800N/ACharpy Impact StrengthKJ/m²2020TBATBAShore Hardness75TBATBAN/ATemperature Rating℃ ℉2000 36322000* 3632*2000 36322000 3632Notes:∥ Parallel to fiber Axis ⊥ Perpendicular to Fiber Axis * Possible to use at higher temperatures at users discretion.
