I'm designing a custom ultra stiff strut bar for a car. Achieving extreme stiffness usually adds a lot of weight, so I am looking into ways to reduce the weight. Honeycomb plates are extremely light, but are only stiff in certain directions. This is perfect for my application since I am transferring forces in a very controlled manner. My question is, how stiff are honeycomb plates under bend? That is, one side being held perfectly perpendicular, and a force applied tangentially to the other end. Also, in what direction is the honeycomb strongest? Thanks.
