ABSTRACT:
Laminates comprising at least one reinforcing layer, for example of metal or of fiber-reinforced duroplast resin, bonded to a foamed polyimide layer are disclosed, wherein the particular nature of the polyimide foam imparts high temperature strength properties to the laminates and permits them to be made by methods, also disclosed, employing more extreme conditions of temperature, pressure, and time than are otherwise operable for making conventional laminates.
