Hello,

I recently purchased a panel of your 4.8 mm Nomex honeycomb, thickness 10 mm. I have a project where I need to bend a strip of the honeycomb about 5 cm wide into a cylinder and glue it on the inside of a tube with a radius of 100 mm. What happens is that the honeycomb gets warped (picture attached) and I could only glue it on the edges. Does anybody have any advice how to solve that? Is this a characteristic of this particular honeycomb or do all behave like that?

This is a characteristic of honeycombs in general.  If you were bonding it and holding it in place using a vacuum bag then you would probably be ok.  Aluminium honeycomb may be easier to use on a curve as you can take the curve out by very slight compressing of the cells around the curve.

I am willing to use Nomex paper honeycomb sheets for my project work, is there any specific process to bend it and give it a shape? or if you know any research paper having the info related to the bending process of nomex honeycomb or honeycomb composite, then kindly share the name or DOI of the paper. 
Thanks
