摘要:
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.
摘要:
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.
摘要:
A rear window shelf (10) for motor vehicle integrated with supports for objects with end pins (11) to fit into seats made on the sides of the vehicle to be rotated, the rear window shelf (10) having an upper surface (12) exposed inside the vehicle and a lower surface (13) which becomes an inner upper wall of a boot compartment, in which the lower surface (13) of the rear window shelf (10) is provided with series of supports (17-19; 20-22; 23) which hold the various objects. The supports are elastic elements which can be hooked, nets with elastic perimetric ring or hooks for objects.

摘要:
A roof panel lining of a vehicle with preassembled head protection elements so-called “head-bag”, comprising a complex element (22) with a head bag unit (25) with a shaped support (26a, 26b) and arranged integrally in relation to a roof panel lining (11) by reciprocal constraining elements (28, 29; 27, 30), in which the complex element (22) is arranged in a recessed zone (17) of the roof panel lining (11), covered by one or more longitudinal side covering and closing elements (18), in turn fastened to a body (14) of the vehicle by a handle (38) and provided with a weakening notch (43) which, in the inflation phase, allows release of a bag of the “head bag” unit (25).
摘要:
A multilayer product which comprises a first element consisting of a layer of spongy, semi-rigid polymer (A), impregnated on one or both sides with polyurethane resin (B), and inserted between two layers of glass fibre, natural fibre or a combination of glass fibre and natural fibre (C) coupled with the central layer (B) (A) (B), wherein the first element is coupled with at least a second element comprising a layer of spongy, semi-rigid polymer (A) , wherein the second element is impregnated on one or both sides with polyurethane resin (B), and wherein the second element is coupled with an additional layer of glass fibre, natural fibre or a combination of glass fibre and natural fibre (C).
