Cellular gradient polymer composites

The invention relates to a foamed polymer composite product incorporating several fillers and/or fibres and several pores characterized by the fact that it shows two distinct gradients, namely a filler and/or fibre density gradient and a pore density gradient. The polymer composite according to the invention may advantageously be used in tissue engineering, bone replacement, consumer goods, transportation or in any other suitable field. The invention also includes a process for manufacturing said polymer composite.
