    Abstract: A laminated structural panel consisting of two plastic saturated sheets on opposite sides of a rigid foam plastic core. The core is foamed and cured between the sheets, each of which has previously been united with a fiber matting. The matting disperses throughout the core as it is foamed to reinforce the core and mechanically hold it to the sheets.
