Abstract
A light-weight structural panel is formed by pultruding a closed-cell foam core embedded with high-strength reinforcing pins through a pair of heated platens along with upper and lower sheets of woven fiber glass wetted by a polymer resin. The lengths of the reinforcing pins exceeds the thickness of the core so the platens compress the skin sheets forming pockets which accumulate excess resin that, when it cures, forms a more stable panel.
