Bending Nomex honeycomb

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?

It quite works on mild flat panel. If the shape is more complex, you have to fix the core in correct position over the vacuum bag during vacuuming. That's a nightmare work...
