    Abstract: Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.

    Abstract: A plastic laminate (10,12,14) includes three nominal layers (16,18,20), each formed of a selected thermoplastic polymer. A top layer (16) is formed from one or more sheets (17) of a first acrylic material. A second, intermediate layer (18) is formed of one or more PVC sheets (19), at least one of which has a face presenting an image that is at least partially viewable through the top layer. The third, bottom layer (20) is formed of one or more sheets (21a,21b) of either a second acrylic material (which may be the same as the first acrylic material) or an ABS material. Preferably, the bottom layer has a thickness at least as great as the thickness of the top layer. Relatively thicker top and bottom layers are preferably formed of multiple plies of like-thickness sheets which are bonded to one another when the top, intermediate, and bottom layers are hot pressed.
