Abstract: Methods for fabricating three-dimensional microstructures are provided. The method includes disposing a reflow material on a mold, heating the reflow material, and creating a pressure gradient across the reflow material to reflow the material towards a bottom surface of the mold. The mold includes a molding region, a boundary region, and a thermal-isolating region disposed therebetween. The molding region includes a cavity and a projection projecting upwards from a bottom surface of the cavity. The thermal-isolating region includes at least one pocket formed adjacent to and along a perimeter of the cavity of the molding region. During heating, the temperature of the molding region is higher than that of the boundary region and the thermal-isolating region controls the thermal conductivity and mass therebetween.

Abstract: In one embodiment, a method for making a high density structural composite includes depositing a plurality of fibrous materials on or adjacent a first plate or surface. A polymer liquid is deposited onto the plurality of fibrous materials to form a composite mixture. A first cyclic pressure is applied onto the composite mixture to compress the composite mixture. In some embodiments, the cyclic pressure may then be reduced to a valley pressure to complete a pressurization cycle. In some instances, the valley pressure may be below atmospheric pressure to induce trapped air and volatile gases to escape from the composite mixture before curing. The pressurization cycle may be repeated. A second pressure, which may be a constant pressure in some embodiments, may be applied to the composite mixture using, in some embodiments, a second plate until the polymer liquid has at least partially cured or partially solidified.
