The present invention discloses a structural panel sequentially comprising a first face sheet having an outward facing thermoplastic surface and an inward facing bonding surface, a first thermoplastic bonding layer, a titanium honeycomb core, a second thermoplastic bonding layer, and a second face sheet having an outward facing thermoplastic surface and an inward facing bonding surface. The face sheet is formed by thermally consolidating a thermoplastic laminate composite and a bonding layer. The face sheet bonding surface and intermediate bonding layer are made from thermoplastic resinous materials having comparable melt temperatures that are lower than that of the thermoplastic materials of the laminate composite. The present invention also provides a method for fabricating a structural panel having thermoplastic face sheets and a titanium honeycomb core that includes the steps of forming a first and second thermoplastic face sheet; preparing a titanium honeycomb core for bonding to the face sheets; and thermally consolidating a panel assembly sequentially having a first face sheet having an outward facing thermoplastic surface and an inward facing bonding surface, a first thermoplastic bonding layer, a titanium honeycomb core prepared for bonding to the face sheets, a second thermoplastic bonding layer, and a second face sheet having an outward facing thermoplastic surface and an inward facing bonding surface.
