A composite formed of a polymer matrix phase having a reinforcement phase including polymeric microfibers. The microfibers are preferably formed of a highly oriented polymer, having a high modulus value and a large surface area. The large surface area can serve to tightly bind the microfibers to the polymer matrix phase. The microfibers can be provided as a fully-or partially-microfibrillated film, as a non-woven web of entangled microfibers, or as a pulp having free fibers. The microfibers can be embedded in, or impregnated with, a polymer or polymer precursor. Some composite articles are formed from thermoset resins cured about a highly oriented polypropylene microfiber reinforcement phase, providing a strong, tough, moisture resistant article. One composite includes a matrix and reinforcement formed of the same material type and having substantially equal refractive indices, allowing the composite to be optically clear.

What is claimed is: 1. A method for making a composite article, the method comprising the steps of: providing a polymerizable monomer or resin; providing a microfibrillated article comprising oriented microfibers having an average effective average diameter less than about 20 microns and a transverse aspect ratio of from 1.5:1 to 20:1; contacting the microfibrillated article with the monomer; and polymerizing the monomer(s) or resin into the matrix polymer. 2. A method for making a composite article as in claim 1, wherein the microfibers of the microfibrillated article have a surface area of at least about 3 square meter per gram. 3. A method for making a composite article as in claim 1, wherein the microfibers have a draw ratio of 10:1. 4.

A method for making a composite article as in claim 1, wherein the monomer is a precursor to a thermoset polymer. 14. A method for making a composite article as in claim 1, wherein the monomer is a precursor to an elastomeric polymer. 15. A method for making a composite article comprising the step of laminating at least one microfiber layer further comprising oriented microfibers having an average effective average diameter less than about 20 microns and a transverse aspect ratio of from 1.5:1 to 20:1 to at least one polymer matrix layer. 16. The method of claim 15 wherein said polymer layer is a thermoplastic polymer layer. 17. The method of claim 16 wherein said microfiber layer further comprises engineering fibers. 18. A method for making a composite article, the method comprising the steps of: providing a thermoplastic polymer; providing a microfibrillated article further comprising oriented microfibers having an average effective average diameter less than about 20 microns and a transverse aspect ratio of from 1.5:1 to 20:1; contacting the microfibrillated article with the thermoplastic polymer with heat and/or pressure. 19. The method of 18 wherein the thermoplastic polymer is injection molded. 20. The method of 18 wherein the microfibrillated article is extrusion coated with thermoplastic polymer. 21. The method of 18 wherein the microfibrillated article and thermoplastic polymer are laminated together.
