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.

A rigid polymeric modular flooring plank that contains chlorinated polyvinyl chloride (CPVC) in the core or base layer. The rigid polymeric modular flooring plank has at least a polymeric core or base layer, a decorative layer, and a wear layer located above the decorative layer. The CPVC can offset the negative effects from any plasticizer present in the core layer, and thus permits the core layer to include plasticized material such as from recycled or reclaimed sources including rework and scrap materials. Methods of making the planks are further described. A method to control dimensional stability of a polymeric flooring plank is further described.
