Though I agree on the use for it on this chassis w/o the modification i mentioned above w a sliced chassis and a mono shock. | Drop a piece of Carbon fiber with 4lbs of weight on it from 4 feet and then drop a piece of delrin with the same and see what happens to the carbon fiber. as always the epoxy cracks or hairlines. which in turn weakens the carbon fiber. Delrin will more likely take the abuse as it has a better flex rating due to its oil based composite structure.
Im not saying you cant make a Carbon fiber chassis, Im saying the give and take resitance is a huge differance. The reason it is cross patterned is to take shock and it depends on how it is made and with what types of material.
Ohh and in case no one realizes this. Carbon fiber does effect radio signal. This is why it is widely no longer used for most RC Heli and RC Plane applications. There are many products still on the market, but it doesnt mean that its a good prodyct when use of radio signal is involved.
Most carbon fiber material you see used in RC are concidered class III, a weaker cheaper material used more for looks than strength. its cheaper to make and are based off a pitch based material of carbon and base B Exoxy. This is known a (CAN)
Colyacrylonitrile thisaline
These are products made for Auto accessories, RC toys, Cell phone covers. Things that can take some impact, but are not based on protection.
the Class I products are truely a much better brand based off a Rayon or Strung kevlar material and suited in a base A Epoxy resin with polymer. Mostly used in commercial applications. This form of CF is known as (PAN)
Polyacrylonitrile phenoline
These are products made for Automotove hoods, performance parts in commercial use, ect where its imparative that the material be made to take abuse to protect something and still mantain structure.
The cost differance is huge in comparrison. |
