High Modulus Carbon Tubing
Very high stiffness ◾ Great thermal conductivity ◾ Strength similar to standard modulus carbon tubes ◾ Ideal for minimal bending
Within the carbon fiber family, there are modulus variations not unlike different grades of steel or alloys of aluminum. High modulus (HM) carbon fiber tubing offers great stiffness and thermal conductivity, and these properties increase with the ultra high modulus (UHM) option. But with all benefits there are some compromises. High modulus tubes have about the same strength as standard modulus tubes and ultra high modulus tubes are not as strong as standard, but they are still significantly stronger than metal. Cost effectiveness will depend on your specific program objectives. We can help you decide what’s best for project.
- Most commonly used to measure the stiffness of a tube or plate
- Units used are typically in msi (million pounds per square inch)
- If tubes (or plates) have the exactly the same layup and fiber orientation, the higher the modulus, the lower the deflection or bend
- Units used are typically shared in ksi (thousand pounds per square inch)
- The maximum stress that a material can withstand while being stretched or pulled before failing or breaking
Carbon Fiber Material: Modulus, Strength, Benefits, Features
- 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 and 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.
