摘要:
The invention relates to an apparatus for manufacturing a composite panel (28) comprising a first and a second copper sheet (2, 3) opposite to each other and adhering to a double sided adhesive film (4) interposed therebetween. The apparatus includes a first and a second lamination stage (1, 2). The first lamination stage (1) comprises a first and a second cylinder (5, 6) crossed by a first belt (7) made of PET on which the first copper sheet may be laid. The cylinders rotate in opposite directions, so as to cause the first belt and the sheet laying thereon to slide therebetween. The first cylinder is partially surrounded by a second belt (10) made of PET and by the double sided adhesive film which is thus dragged between the aforesaid cylinders and is caused to adhere to the first copper sheet so as to form a semi-finished panel (16) comprising one of the two copper sheets and the double sided adhesive film. The second lamination stage (2) comprises a third and a fourth cylinder (21, 22) crossed by a third belt (23) made of PET on which the semi-finished panel may be laid at the first copper sheet. The cylinders rotate in opposite directions so as to cause the third belt and the semi-finished panel laying thereon to slide therebetween. The second lamination stage also comprises a chute (25) on which the second copper sheet (3) may be laid and by means of which the latter may overlap the semi-finished panel at the double sided adhesive film included in the latter. The third and fourth cylinders compress the second copper sheet against the double sided adhesive film of the semi-finished panel so as to form the aforesaid composite panel.

A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.

Described herein are organogermanium modification layers and associated deposition methods and inert gas treatments that may be applied on a sheet, a carrier, or both, to control van der Waals, hydrogen and covalent bonding between a sheet and carrier. The modification layers bond the sheet and carrier together such that a permanent bond is prevented at high temperature processing as well as maintaining a sufficient bond to prevent delamination during high temperature processing.

Underbody shield materials that can provide an underbody shield with high impact resistance are described. In some configurations, an underbody shield composition comprises a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material. In some instances, the underbody shield composition may also comprise a film such that an underbody shield produced from the composition can withstand at least 50 individual impacts as tested using a SAE J400 protocol.
