Carbon fibre is well-known for being one of the worlds lightest and strongest materials. In this video by Hydraulic Press, a Finish based YouTube channel intent on squashing anything and everything with a hydraulic press, put different pieces of carbon fibre composite to the test.
First up was a piece of carbon fibre tubing places on its side, then a section of driveshaft, designed to withstand twisting forces, and finally a carbon fibre sandwich which proved too much for the press and was only defeated when a nut was added to the surface.
Instead of shattering the carbon fibre almost disintegrates as the weave breaks down. These pieces of carbon fibre composites are made to be extremely strong in one direction but when you pressurise it in a different angle the material will completely implode rather than slowly deform like steel.
