Abstract: Method for producing a multilayer composite material, according to which said multilayer composite material, multilayer composite material obtained by the methosod and mechanical parts or structures produced with said material. The present invention. concerns a method for producing a multilayer composite material, according to which said multilayer composite material comprises one or a plurality of thermoplastic polymer layers, one of which is a surface layer (1) comprising a thermoplastic polymer A, and comprises a substrate layer (2) comprising a thermoplastic (meth)acrylic polymer matrix and a fibrous reinforcing material, said method involving cutting at least one window in the thermoplastic polymer layer or layers and at least one window in the fibrous material, said windows being intended to coincide; impregnating the fibrous material with a liquid (meth)acrylic syrup such that it fills said windows, or inserting a transparent thermoplastic plate into said window; polymerizing the liquid (meth)acrylic syrup impregnating the fibrous material and present in the absence of a thermoplastic plate in the window or windows. The invention is applicable applies to the production of mechanical parts of structured elements or decorative items made from multilayer composite material and requiring transparent windows.
