Carbon fiber or Polyurthane
So I was looking at two different splitters for my car one carbon fiber and the other polyurethane now I don't really know the difference ? Which one is better ? Which ones Stronger?? Is there a difference?
Now some of you are going to be like "google it " but I want first hand experienced responses. Tell me what one u think is better !! |

carbon fiber is strong for how light it is.
compared to the same thickness and weight of PUR (polyurthane) it will be stronger. most people buy carbon fiber to keep them bare carbon with no paint. if you are going to paint it is wasting your money to get carbon. saying that, the price of PUR painted vs bare carbon, will be very close. |

CF is more aesthetically appealing to some. If you're going to paint it, get the poly. CF is probably more expensive anyway.

while carbon fiber is very strong in tensile strength, it is very brittle in compressive strength. what that means is that when you bottom out your splitter, carbon fiber is much more likely to crack and shatter, where as poly will bend a lot more before it breaks.
Poly will be more durable in everyday use. I'd much rather use poly in a place where it might see some impact. |
