An synthetic wood composite ball bat (10) having no wood components comprises a rigid shell of fiber reinforced composite material filled with expansible urethane foam to develop compressive stressed therebetween. The foam is locked to the shell during the manufacturing process by use of an intermediate dry woven fiber tube into which resin from the composite shell flows during curing of the composite shell and into which urethane foam flows during expansion of the urethane foam filler.
