Methods and systems for making fiber reinforced moldable mixtures for making FRP products by mixing and/or compounding of at least one, normally hot, polymer and at least one wet fiber product. Intermediate FRP moldable mixtures and finished FRP products produced by the methods and systems are also disclosed. The polymers preferred are thermoplastic polymers, but mixtures that form thermoset polymers are can also be used. Wet fiber product(s) containing water, a solvent, or other liquid are used by the systems and methods disclosed. Packaged wet roving fiber strand products are also disclosed. The FRP products made with the invention have lower cost, more complete and uniform fiber dispersion and/or more uniform and improved appearance and/or physical properties than conventional FRP products made using conventional dry reinforcing fiber products.
