Engineering Model for Paperboard Laminates

Abstract

Paperboard laminates consist of single paperboard sheets flat laminated together, using an adhesive inter-layer. In contrast to fiber reinforced plastics like e.g. carbon fiber composites, where fibers are trapped in an epoxy resin matrix, paperboard laminates don’t consist of a matrix-fiber construct. Instead, the cellulose fibers of the paperboard sheets are connected to each other by hydrogen bonds. The in-plane structure of fiber reinforced plastics (FRP) composites possesses more distinctive principal directions with respect to paper materials, for which the distribution of fiber orientation can be idealized by an ellipse form. [GÖTZINGER, 2021] Despite structural differences, paperboard laminates and fiber reinforced composites exhibit similarities in their mechanical behavior.
