A method for producing a polylactic acid (PLA) shaped article by thermoforming and thermoformed PLA articles. The method for producing a shaped article includes: heating a sheet of crystallizable polylactic acid (PLA)-based resin having a ratio of cold crystallization over total melting enthalpy (ΔHcc/ΔHm) greater than 0.70 as determined by differential scanning calorimetry (DSC), wherein heating includes a heating step the sheet is heated from a surface temperature of at most 80° C. to a surface temperature of at least 90° C. to at most 150° C. at heating rate of 5° C. to 25° C. per second, to provide heated sheet having a ratio of cold crystallization over total melting enthalpy (ΔHcc/ΔHm) greater than 0.5 as determined by DSC; and immediately after heating, forming heated sheet to provide a shaped article by means of a mold having a temperature of at least 70° C. and at most 120° C.

A ballistic-resistant composite includes at least one layer that has a network of ballistic fibers and a resin matrix. The resin matrix includes blocked isocyanate that is composed of isocyanate bonded with a blocking agent. The resin matrix is cross-linkable by heating to a temperature that causes the isocyanate to liberate from the blocking agent and the liberated isocyanate to reactively cause cross-linking of the resin matrix.

A method of forming a polishing pad that has a polishing region and a window region, wherein both regions are made of an interpenetrating polymer network formed from a free-radically polymerized material and a cationically polymerized material.

Described herein are resilient floor coverings produced by using digitally printed UV-cured inks and exhibiting high adhesion properties between an ink layer and a wear layer. Also described herein are methods for manufacturing same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Provided are a molded article excellent in a Charpy impact strength and a method of producing the same. A molded article contains a methacrylic resin composition containing at least one methacrylic resin, in which a pencil hardness is 2 H or higher, and a craze formation time is 19 seconds or longer, the craze formation time being measured by sequentially performing the following steps 1) to 5): 1) preparing a test piece that is a strip-shaped molded article, the test piece having a through-hole provided on one end side in a longitudinal direction; 2) heating and drying the test piece; 3) clamping the other end side of the test piece in the longitudinal direction and fixing the test piece to a fixing table so that extending directions of an upper surface and a lower surface of the test piece coincide with a horizontal direction; 4) applying ethanol one or more times to a predetermined region of the upper surface while generating a surface stress on the upper surface by applying a load calculated by a specific equation in a vertical direction at a position where the through-hole of the test piece is provided, and maintaining a state in which the ethanol is applied; and 5) obtaining the craze formation time by measuring a time from the start of the application of the ethanol to the formation of the craze in the test piece.

A net-shape ballistic panel is formed by a process of arranging a fiber bundle on a substrate to form a layer, the layer following a shape of the ballistic panel, securing the fiber bundle to the substrate with a plurality of stitches to form a preform layer, arranging additional layers of fiber bundles on the preform layer, each layer of the additional layers following the shape of the ballistic panel, and each fiber bundle being secured with a plurality of stitches to each layer of the additional layers to form a plurality of preform layers. A resin is then impregnated into the preform layers and subsequently cured using a process such as compression molding. The resulting ballistic panel is relatively thin while exhibiting an excellent ballistic rating (e.g., V50).
