Group: Forum Members Posts: 26, Visits: 301	Hi guys, I hope somebody can help me. I have to make a 27,2mm diameter tube, and to make this I'will wrap more times a single sheet of carbon around a 1" diameter tube (25,4mm). the tube will be used to be connected to the hull of a saddle I'm going to create. My question is: does anybody know the thickness of a single layer of carbon? In this way I will know the number of wrapping I have to do in order to reach the 27,2mm. Consider that, after the wrapping, the created tube will be closed into the bag and used with the vacuum bagging, so that the carbon will be more compressed. In the end I will give a layer of glossy finishing. Thanks a lot for the help

If you're using regular 200g fabric, then each layer is approximately 0.25mm when consolidated under vacuum. How accurate do you actually need to be? I think you might struggle to get it to exactly 27.2mm, especially if you are using wet lay. Edited 10 Years Ago by Hanaldo

I use 200gr Plain fabric so, if you say its final thickness is 0,25mm I should wrap 7 layers. That's why 27,2mm - 25,4mm = 1,8mm (thickness of the carbon tube I have to make) So 0,25 x 7=1,75mm that should be good enough I will let you know, thanks Hanaldo (24/04/2015) Depends on the weight of fabric you are using.
