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.
  • Artful appearance
