Most commonly used to measure "How Stiff" a tube or plate is
Units used are typically in msi (million pounds per square inch)
Considering a tube/plate with exactly the same "layup / 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
Standard Modulus | 34 msi, 700 ksi | Good structural properties - Stiffer than aluminum
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.
We have been using the high mod for around 3 weeks now. Extremely light weight and very rigid. I would highly suggest the upgrade.
