Tube - Intermediate & High Modulus Blend - Fabric Plain Weave - 1.250 X 1.344 X 92.0 IN
1.250" ID Carbon Fiber Tube – Intermediate & High Modulus Blend
This carbon fiber tube features a strategically engineered blend of intermediate and high modulus fibers, delivering an exceptional balance of strength, stiffness, and durability. High modulus fibers run longitudinally to maximize bending stiffness, while intermediate modulus fibers in the hoop direction improve crushing resistance and overall structural integrity. :contentReference[oaicite:0]{index=0}
Constructed using precision roll-wrapped prepreg materials, this tube offers consistent performance and reliability for demanding applications. The 1k plain weave outer layer provides a clean, professional appearance with a durable gloss (cello wrap) finish.
Key Features
- Blended Modulus Design: Optimized stiffness and strength in multiple directions
- High Bending Stiffness: High modulus fibers reduce deflection under load
- Enhanced Crush Strength: Intermediate modulus hoop plies improve durability
- Precision Construction: Roll-wrapped for consistent quality and performance
- 1k Plain Weave Finish: Lightweight with a clean cosmetic appearance
Features & Benefits
Carbon Fiber Material | Modulus, Strength | Benefits, Features & Notes
- Standard Modulus | 34 msi, 700 ksi | Good structural properties - Stiffer than aluminum - Readily available
- Intermediate Modulus | 42 msi, 825 ksi | Great structural properties - Highest strength option - Great balance of stiffness and strength
- High Modulus | 57 msi, 670 ksi | Very stiff - Good thermal conductivity / stability - Typically used in all 0° & 90° (or off-axis) plies throughout the ply sequence / laminate orientation.
- Ultra High Modulus | 94 msi, 414 ksi | Stiffest option available - Great thermal conductivity - Used primarily as 0° plies in combination with lower modulus / higher strength fibers in the 90° orientation to create a well-balanced and functional composite structure.

- 0° fibers maximize bending stiffness and run along the length of the part. Consider bending a tube over your knee.
- 45° fibers maximize torsional stiffness and are typically plied together in an opposing manner, i.e. ±45°. Consider twisting a tube like a vehicle's driveshaft.
- 90° (or "hoop") fibers maximize crushing stiffness and generally assist in overall durability. Consider laying a tube on the ground and stepping on it.
