Table 1. Mechanical properties of Flag fibers with different values of the alignment parameter, α.
| α | Einitial (GPa) | σu (GPa) | εu | WF (J/m3) |
|---|---|---|---|---|
| 0 (MS) | 5 ± 1 | 800 ± 100 | 0.76 ± 0.08 | 250 ± 50 |
| 0.45 | 7 ± 1 | 900 ± 100 | 0.67 ± 0.03 | 250 ± 20 |
| 0.9 | 6.5 ± 0.6 | 730 ± 70 | 0.41 ± 0.04 | 140 ± 20 |
Einitial: slope of the initial linear part of the true stress-true strain curve. σu: True stress at breaking. εu: True strain at breaking. WF: Work to fracture, measured as the area under the stress-strain curve up to the breaking point. Values shown as mean value ± standard error.
