Abstract

Multifunctional surfacing materials for use in composite structures are disclosed. According to one embodiment, the surfacing material includes (a) a stiffening layer, (b) a curable resin layer, (c) a conductive layer, and (d) a nonwoven layer, wherein the stiffening layer (a) and the nonwoven layer (d) are outermost layers, and the exposed surfaces of the outermost layers are substantially tack-free at room temperature (20° C. to 25° C.). The conductive layer may be interposed between the curable resin layer and the stiffening layer or embedded in the curable resin layer. According to another embodiment, the surfacing material includes a fluid barrier film between two curable resin layers. The surfacing materials may be in the form of a continuous or elongated tape that is suitable for automated placement.
