honeycomb cutting in aluminum or nomex

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.

Aluminum honeycomb has been widely used in many industrial fields, especially the aeronautics and aerospace industries, owing to its high strength and stiffness to weight ratio. Machining of aluminum honeycomb is usually associated with deformations and burrs. Ultrasonic cutting has been introduced as a promising method to overcome these constraints.


2020-2-20 · Aluminum honeycomb also has the problem that it has no “mechanical memory.” On impact of a cored laminate, the honeycomb will deform irreversibly whereas the FRP skins, being resilient, will move back to their original position. This can result in an area with an unbonded skin with much reduced mechanical properties. Nomex honeycomb

Nomex Honeycomb Ultrasonic Machining - Industry Application. The application in Nomex honeycomb has skyrocketed recently through aerospace and defense industries. Due to its lightweight and tough structure, It is normally used in aerospace sandwich structure to reduce wings weight and increased the endurance within high impact and stress.


Nomex® is slightly more costly than aluminium honeycomb, so is generally used where the increased thermal resistance and formability advantage are required. These increased costs are mainly due to a slightly more complicated manufacturing process, higher wastage and more costly certification that is required especially for the aerospace grades.
