ABSTRACT:
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.
