A composite construction panel and process for its fabrication. The contruction panel has a lightweight cellular insulation core adapted for receiving imbedded electrical conduits and further includes a cementatious fireproofing layer. The panel is completely clad within glass fiber reinforced concrete. In addition, reinforcing steel can be incorporated into the concrete encasement. Adjacent panels are designed for bolted and/or adhesive interconnection with registration of the respective conduits thus forming a continuous internal conduit network. The method of fabrication includes a molding operation wherein a rigid foam core is formed from a flowable urethane composition, the core is bonded to the fireproofing layer and then enveloped within a cement matrix having glass fibers. Mold inserts are utilized to provide void areas such as for window and door openings, bolt connection pockets and utility box placement. The panel can be manufactured in planar and simple and compound curve shapes.
A molded composite construction panel formed in a continuous molding procedure and suitable for casting curvilinear structural components comprising a lightweight cellular core of rigid foam material, said core having a cementaceous fireproofing layer interfacially bonded to one side of said core, a relatively thin skin of sprayed glass fiber reinforced concrete encasing said core and fireproofing layer, said panel further including at least one integrally formed lateral rib section of said fiber reinforced concrete, said rib section being coextensive with at least one side of the panel and including connection means for securing adjacently placed panels.
