摘要:
A multilayer web panel with improved impact resistance having two substantially flat exterior walls and webs connecting the walls as one piece. At least one exterior wall has at least two adhesively bonded layers of one or more plastics, wherein the bearing layer of the exterior wall consists of an acrylic glass layer which is about 50% or more of the total thickness of the exterior wall, and the inner side of the acrylic glass layer has a thinner inner layer which is adhesively bonded thereto and is made of a plastic with a higher elongation at rupture than that of the acrylic glass.
