A fiber reinforced thermoplastic composite panel is described. One use of the panel is to construct bridge decks although the panel may have several other uses. It comprises two flat plates formed of commingled glass fiber reinforced polypropylene secured in spaced parallel relationship to a core. The core is formed by either two corrugated sheets interconnected together along connecting ridge sections or else by a plurality of elongated FRP channel members disposed transversely between the flat plates. The corrugated sheets or channel members form hollow core spaces between the two flat plates and the core material and these hollow spaces are filled with a filler material to add stability to the panel. Both the flat plates and the core material are formed of commingled glass fiber reinforced polypropylene (FRP).
