A sandwich material comprising two metal plates affixed to and separated by a fibrous core, is characterised in that the core comprises a three-dimensional porous network comprising metal fibres, wherein substantially all of the fibres are inclined at an acute angle to the plates. The sandwich material is lightweight, thin and handles like a monolithic sheet. It displays high beam stiffness and is easy to weld. It as therefore particularly useful in the manufacture of aircraft and vehicle parts.
