Table 1 Main physical and mechanical properties of the three types of fibres.
Fiber type | Length, in mm | Diameter, in mm | L/D | Bending performance | Elasticity modulus, in GPa | Tensile strength, in MPa |
|---|---|---|---|---|---|---|
Ordinary steel fiber | 35 | 0.87 | 40 | > 90 | 210 | 425 |
Ultrashort ultrafine steel fiber | 6 | 0.2 | 30 | > 90 | 240 | 880 |
Flexible fiber | 12 | 0.03 | 400 | > 90 | 3.85 | 500 |
