The invention relates to multi-layered composite materials and methods for making multi-layered composite materials having good adhesion between the layers. The adhesion between a polymer layer and a metal layer of a multi-layered composite material may be improved by a process including a step of pre-treating a surface of the metal layer prior to contacting the metal surface with the polymer layer, and by including filler particles in the polymer layer. Using this approach, it is possible to increase the peel strength by about 10% or more, by about 20% or more, by about 40% or more, or by about 100% or more, compared with an otherwise identical composite material that does not include both of these features.
