    摘要: A metal-plastic-metal structural laminate which can be formed into various useful articles having compound curves using conventional metal forming techniques. The laminate comprises two metal skin layers and a centrally disposed polymer layer comprising a core layer, and optionally first and second adhesive layers. Each metal skin layer is 2 to 20 mils, the ratio of the core thickness to skin thickness is less than 9:1 and the total laminate thickness is 5 to 65 mils. The laminate can be bent to 90.degree. to a critical radius, the distance between the pivot point and the inner skin surface of the laminate, without metal rupture.

    摘要: A method for adhering a coating material to at least one surface of a densified random-fiber composite sheet is provided. The method comprises applying sufficient heat to a surface of the composite sheet to form an activated surface whereby the fiber component of the sheet is projected outward from a plane defined by that surface, and contacting the activated surface with the coating material. The coating material is generally of a viscous or liquid nature such that it can physically interact with the projected fibers to adhere thereto. A method for adhering asphalt to a metal substrate employing a densified random-fiber composite sheet is also provided wherein the metal is coated with an adhesive and then adhered to an activated surface of a composite sheet. Asphalt is then coated onto the exposed surface of the composite sheet which has been activated or is activated by coating with hot asphalt.
