High-performance racing bicycle frames can be manufactured using either aluminium alloy or carbon fibre composite.
| Property | Aluminium alloy | Carbon fibre composite |
|---|---|---|
| Density / g/cm3\text{g/cm}^3g/cm3 | 2.70 | 1.60 |
| Relative strength | 1.0 | 4.0 |
| Vibration damping | Low | High |
| Corrosion resistance | Medium | High |
Explain two reasons why carbon fibre composite is preferred to aluminium alloy as the material for high-performance racing bicycle frames.
