It is also flexible. This material is also tough. A bumper made entirely of carbon fibre is the lightest available
5.0.0 ADVANTAGES AND DISADVANTAGES OF EACH BUMPER MATERIALS
1. Can have an attractive finish and wide range of decorative finishes available
2. Steel has the highest melting point so less likely to degrade under higher temperatures so it is ideal for the outdoor environment.
3. Has the highest strength, hardness and durability in other bumper materials
4. Has a wider range of processors available for manufacturing …show more content…
It is thought as bumper material, without sacrificing its shock absorbing capacity. Its lightness also helps the bumper become aerodynamically efficient. Ceramics are strong but very brittle, so would not usefully absorb the kinetic energy of impact. The most promising are the relatively new carbon nanotubes. The promising characteristics are as follows:
(1) Carbon Nanotubes can have Young's modulus as high as 1 terra Pascal, so it is ideal as a strong bumper material
(2) Carbon nanotubes have the greatest of both tensile strength and elastic modulus. 
(3) A carbon nanotube is very hard. Standard single-walled nanotubes can tolerate a pressure of about 24GPa without being deformed. The highest pressure that the material can tolerated under experiments techniques is 55GPa. It has a greater bulk modulus of 462-546 GPA than that of the diamond.
(4) Resources to manufacture them is very abundant and from a few materials many can be constructed
(5) They are functional even in the extreme temperatures
