Does Carbon Fiber tape around seatpost make it a Carbon Fibe seatpost?
Hi I hae something creative in mind. Will wrapping around my alloy seatpost with several carbon fiber tape reduce vibration ?
Will first of all I'm not sure if the purpose carbon fiber on bikes is to vibration and weight

Nope. Vibration will still be transmitted through the aluminum. The vibration dampening of carbon fiber composites comes from the way all of the materials deform together.
Plus, you'll be changing the size of the seatpost and it won't fit in the seat tube anymore.

As noted, you can't increase the diameter of your seatpost and still have it fit. If all you planned to do was wrap carbon tape around the exposed portion of the seatpost you will only change the cosmetics and have no other benefit.

The frequency of vibration dampening will be changed by adding weight to the seat post.
CF is one way. Another would be filling the seat post with molten lead or a slug of depleted
uranium for maximum effect. You seem to want more vibration ("reduce vibration dampening"
as you phrased it) so a steel seat post might be a better idea. Steel vibrates a bit better
than aluminum or CF.

Why would you suggest filling a seatpost with a toxic substance like lead? A solid steel rod would be just as effective, and less hazardous to one's health.
I'm currently working on wrapping cardboard tubes from paper towel rolls with carbon fiber tape. Predicted weight for the full carbon frame is under 1.5 pounds.

CF is at least as hazardous as lead if you are cutting the tape to fit. The
small shards of CF produced by the cutting are toxic to the lungs.
The post was TIC, extrapolating on the consequences of the OP's approach.
Otherwise an interesting approach to making a mandrel for a CF frame
using paper towel rolls.

Also a misconception. There are harsh steel bikes too. But I must admit I've never ridden one that had the jack-hammer-up-your-ass effect of some (rather expensive) aluminum frames.

It would be too hard to obtain the PVC elbows with correct angles... I'm not trying to built a chopper with a 45 degree head tube angle...
A respirator will keep out the CF dust...

If you're looking to reduce vibration, for god's sake, don't remove the load bearing decals.

You Know!? For Kids!
For those of you cutting the carbon fiber tape and paper towel rolls, please remember not to run with scissors and to keep the points down. If at all possible, use safety scissors with rounded points.

One time? at camp? Becky Frout had some carbon fiber? And she totally exploded.
