Typical properties for some synthetic fibres [38].
| Material | Density (kg/m3) | Young's Modulus (GPa) |
Tensile strength (MPa) | Tensile strain to failure Ɛf (%) | Coefficient of thermal expansion in the axial direction of fibre (10−6/K) |
|---|---|---|---|---|---|
| E-glass | 2600 | 76 | 2000 | 2.6 | 4.9 |
| Kevlar™ | 1450 | 130/10 (axial/radial) | 3000 | 2.3 | –6 |
| HM carbon | 1950 | 380/12 (axial/ radial) | 2400 | 0.6 | –0.7 |
| HS carbon | 1750 | 230/20 (axial/radial) | 3400 | 1.4 | –0.4 |
