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.
