Abstract
A panel system is recited that includes a first panel having a periphery. The panel includes a first plastic layer having a periphery and a second plastic layer opposed and spaced apart from the first layer. The second layer also has a periphery. The first and second layers define a first cavity therebetween. A first in-situ foam core is disposed in the cavity and has a thermal bond to the first and second plastic layers. The panel is capable of supporting 0.1 to 0.5 lbf/in2.
Claims17
A panel, comprising:
- a first plastic layer having a periphery;
- a second plastic layer having a region opposed and spaced from the first layer, and a periphery joined to the periphery of the first plastic defining at least one substantially enclosed cavity between the first and second layers;
- and
- a foam core of thermally expandable plastic bead filling the cavity when expanded in situ to create a structural core having a thermal bond with the first and second plastic layers, wherein the panel is capable of supporting 0.1 to 0.5 lbf/in2.
