Abstract: An article may be made of multilayer composite material. The multilayer composite material may include central element (I) between first and second reinforcement layers (B) to form structure (B)-(I)-(B). The central element (I) may include: first and second structural layers (A), each of the first and second structural layers (A) including at least one mat of needle punched thermoplastic fibers selected from polyester fibers, polyamide fibers, polypropylene fibers, or mixtures thereof bonded through thermosetting resin; and third reinforcement layer (B) between the first and second structural layers (A). The first, second, and third reinforcement layers (B) each may include fibrous material, including one or more types of fibers selected from glass fibers, natural fibers, carbon fibers, basalt fibers, aramid fibers, or mixtures thereof.

Abstract: The present invention refers to an article made of a multilayer composite material comprising a central element (I) arranged between a first and a second reinforcement layer (B) to form a structure (B)-(I)-(B), said central element (I) comprising: a first and a second structural layer (A) each comprising at least one mat of needle punched fibres of the thermoplastic and/or natural type or else a mat of expanded thermoplastic polymer, said structural layers (A) being impregnated with a thermosetting resin; a third reinforcement layer (B) arranged between said two structural layers (A), said first, second and third reinforcement layer (B) consisting of a fibrous material, comprising one or more types of fibres selected from the group consisting of glass fibres, natural fibres, carbon fibres, basalt fibres, kevlar fibres, aramid fibres or a mixture of such fibres.
