1. A laminate for use in an automated tape laying machine wherein said laminate includes a curable flexible electromagnetic hazard resistance laminate that has an external face having a first tackiness, wherein said external face is to be adhered to a mold surface and an opposing external face having a second tackiness, said opposing external face being adhered to an internal surface of a backing sheet, wherein said backing sheet is pulled from said electromagnetic hazard resistance laminate after said external face is adhered to said mold surface, said laminate comprising:
a releasable backing sheet having an external surface and an internal surface on which a curable flexible electromagnetic hazard resistance laminate is carried, said electromagnetic hazard resistance laminate comprising an external face having a first tackiness and an opposing external face having a second tackiness, said opposing external face being adhered to the internal face of said releasable backing sheet, said electromagnetic hazard resistance laminate comprising:
a conductive layer comprising electrically conductive metal material and thermosetting resin, said conductive layer comprising a first side and a second side located closest to said backing, sheet, said conductive metal material weighing from 50 gsm to 200 gsm;a first veil layer located on the first side of said conductive layer, said first veil layer comprising a mat of randomly oriented fibers, said first veil layer weighing from 5 gsm to 20 gsm;a second veil layer located on the second side of said conductive layer, said second veil layer comprising a mat of randomly oriented fibers, said second veil layer weighing from 5 gsm to 20 gsm; anda first layer of thermosetting resin located adjacent to said first veil layer, said first layer of thermosetting resin forming said external face having said first tackiness; anda second layer of thermosetting resin located adjacent to said second veil layer, said second layer of thermosetting resin forming said opposing external face having said second tackiness wherein the ratio of the amount of thermosetting resin in said first layer of thermosetting resin and the amount of thermosetting resin in said second layer of thermosetting resin is about 2.8:1 and wherein said first tackiness is greater than said second tackiness such that said laminate exhibits the property of being able to have said releasable backing sheet pulled from said electromagnetic hazard resistance laminate, after said external face has been adhered to a mold surface, without detaching said electromagnetic hazard resistance laminate from said mold surface. |
