Carbon fiber driveshaft

Has anybody ever thought about having one built. Like instead of a 2 piece with the cardone joint and a carrier bearing do a 1 piece carbon fiber driveshaft. Has anybody thought about that?

 

Why? It is a pickup truck not a sports car.

 

Im sure its been considered, but the end question is WHY? The price of a carbon shaft would be 6X an OEM part, the weight savings would give you no benefit and all its going to save you is maybe greasing a joint every 30K miles.

So...while its a novel idea....its just not practical.

 

There's a reason you'd be the only one to have one.

 

i like unique things and that would definitely be a very unique item to have. Plus if you consider how strong carbon fiber is.

 

You only grease your u joints every 30k?

 

Unique sure. But still not practical for the cost in a pickup truck.

 

Strong enough to land on a boulder?

 

I know carbon fiber is strong, can handle way more torque than steel. I didn't really think how it would handle an impact.

 

This.

 

CF may be stronger and lighter, but again... it's a Tacoma, and thus a pointless mod.

Kinda like Lambo doors.

And if you use your truck as a truck, or actually wheel, steel is going to be a lot more forgiving for shock and impacts; even it it bends and/or dents a bit, it can still have enough rotational integrity to limp you back to the trail head. CF is very stiff with extremely minuscule elasticity. It cannot appreciably dent or bend, but instead cracks and shatters, leaving you sitting and needing another custom $$$$ driveshaft...

 

What's it's IMPACT resistance compared to a steel one?

my buddy just had a one piece steel shaft made for $500. Double the price for a carbon one piece doesnt seem entirely bad...
