A method for making continuous fiber-reinforced plastic composites is disclosed. It involves the steps of (a) using an extruder to continuously extrude a first plastic resin through an extruder die to form a first plastic resin layer; (b) continuously pulling a plurality of prepreg strips along with the first plastic resin layer; and (c) combining the plurality of prepreg strips with the first plastic resin layer to form a sandwiched composite containing at least two prepreg layers separated by the first plastic resin. The prepreg strip contains reinforcing fibers impregnated with a second plastic resin. The fiber-reinforced and sandwich-structured plastic composites exhibit greatly improved flexural strength and flexural modulus approaching those of real wood, and can be drilled, nailed, chiseled, saw, etc, similar to natural wood.
