Advantages of Fiberous Composite Materials
- High design freedoms：fiber, resin and process selection.
- High specific strength/stiffness：two/five times of aluminum/steel.
- High fatigue resistance：90% / 50% of its ultimate strength for fiber composite/metal material.
- No corrosion protection required：Could be totally avoid the coating/painting process.
Advantages of Carbon Fiber
- Advantages of Carbon Fiber：1/5 of steel and 1/2 of aluminum.
- Fatigue resistance：The static strength of aluminum alloy or steel is 50% whereas the rate is 90% for composite material.
- Anti-corrosion：Under the exposure of air and steam, coating is necessary for metals while carbon fiber is corrosion-resistant, coating is not obligatory.
- Dimensional stability：smaller expansion coefficient, able to produce net shape or almost net shape parts which save post-production cost.
- Structure effectiveness：Minimize the amount of parts by design, which decreases the assembly cost and increases the structural stiffness and effectiveness.
