A resin powder for solid freeform fabrication includes a particle having a pillar-like form, wherein the ratio of the height of the particle to the diameter or the long side of the bottom of the particle is 0.5 to 2.0, the particle has a 50 percent cumulative volume particle diameter of from 5 to 200 μm, and the ratio (Mv/Mn) of the volume average particle diameter (Mv) to the number average particle diameter (Mn) of the particle is 2.00 or less.

The present teachings contemplate forming a reformable epoxy resin material into a monofilament having a denier of from about 50 to about 5000 and a glass transition temperature of less than about 200° C.; loading one or more monofilaments onto a spool; co-weaving the one or more monofilaments with a reinforcing fiber to form a woven material, the reinforcing fiber having a glass transition temperature of greater than 200° C.; heating the woven material to form a composite to a temperature so that only the one or more monofilaments soften but the reinforcing fiber does not.

A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.

A method of forming a polymer-metal nanocomposite (PMNC) material with a substantially uniform dispersion of metal particles includes forming a composite solid preform by mixing a blend of micrometer-sized metal particles and polymer particles and subjecting the mixture to compression followed by sintering. The composite solid preform is drawn through a heated zone to form a reduced size fiber. The reduced size fiber is cut into segments and a next preform is formed using the bundle of the segments. The next preform is then drawn through the heated zone to form yet another reduced size fiber. This reduced size fiber may undergo one or more stack-and-draw operations to yield a final fiber having substantially uniform dispersion of nanometer-sized metal particles therein.
