Mechanical properties of structural profiles
|
When using Fiberline structural profiles for load-carrying purposes, typical ultimate strength and deflection calculations are made. Complete calculations are carried out in accordance with the Fiberline Design Manual which takes the anisotropic properties of the materials into account. |
|
All values listed below are based on measurements carried out in Fiberline’s own laboratories or by independent testing institutes. |
Material parameters

Characteristic stiffness values and transverse contraction
|
[MPa] | [--] | |
| Elasticity modulus | E0° | 23,000/28,000 | |
| Elasticity modulus | E90° | 8,500 | |
| Shear modulus | G | 3,00 | |
| Poisson’s ratio | V0°,90° | 0.23 | |
| Poisson’s ratio | V90°,V0° | 0.09 |
|
The E-modulus of the profiles varies from 23 - 28 GPa depending on the geometry and reinforcement. See Fiberline Design Manual for the load-carrying capacities of the individual profiles. |
|
The material values stated are valid for temperatures between -20°C and 60°C (dry condition). |
| Characteristic strength values | [MPa] | |
| Bending strength, 0o | fb,0o | 240 |
| Bending strength, 90o | fb,90o | 100 |
| Tensile strength, 0o | ft,0o | 240 |
| Tensile strength, 90o | ft,90o | 50 |
| Compressive strength, 0o | fc,0o | 240 |
| Compressive strength, 90o | fc,90o | 70 |
| Shear strength | ft | 25 |
| Pin-bearing strength, longitudinal direction | fcB,0o | 150 |
| Pin-bearing strength, transverse direction | fcB,90o | 70 |
|
Note: For temperatures exceeding 60°C, strengths and stiffnesses must be reduced in accordance with the Fiberline Design Manual. |
|
The Fiberline Design Manual provides dimensioning guidelines, including tables of load-carrying capacities and more specific geometric properties. |
