Abstract

A composite plate of thermoplastics is constituted of two parallel outer layers each having on its inner face anumber of parallel ribs, the ribs of one layer crossing those of the other at an angle and being bonded to them. In a variant, there is an additional intermediate layer also having ribs on both its faces, these ribs crossing and being bonded to the inwardly projecting ribs of the outer layers. In yet another variant, there are two such intermediate layers on the same principle. The ribs of the outer layers are in general parallel within each layer, and may be straight on both outer layers, curved on both outer layers, or curved on one layer and straight on the other. The presence of ribs running in more than one direction gives the same stiffness against bending normally possessed by corrugated packaging material or the like, but in the present case stiffness in every direction.
