Abstract: An additive article stabilizing method includes prior to polymerization, adding a radiation-activated stabilizing composition to a liquid resin, forming the article from the liquid resin, layer by layer, using radiation such that the stabilizing composition does not stabilize the liquid resin but the formed article, and neutralizing free radicals generated during a degradation process initiated by exposure of the article to additional radiation post-cure.

Abstract: A composite part is manufactured by an additive process, which includes locating a layer of fibers, selectively depositing a matrix material in a predetermined pattern onto portions of the layer of fibers to form a matrix material layer, repeating these steps to generate a preform of the composite part, and applying heat and pressure to the preform to consolidate the layers of fiber and the layers of matrix material. During the depositing of the matrix material, voids are created within at least one layer of the matrix material by intentionally not depositing matrix material over predetermined areas of the layer of fibers, the predetermined areas configured to be within an outer boundary of the predetermined pattern of the matrix material.

Abstract: A method of manufacturing an injection molded part includes formulating recycled polyamide material from a waste polyamide powder with at least one crystallization agent and at least one lubricant agent, forming recycled polyamide pellets from the recycled polyamide material, and injection molding a part from the recycled polyamide pellets. The crystallization agent is a metal salt of an organic acid with a content in the recycled polyamide material, in weight percent, between 0.1% and 1.0%, and the lubricant agent is a metal stearate with a content between 100 ppm to 5000 ppm. The waste polyamide powder is waste polyamide powder from a selective laser sintering process, for example waste polyamide 12 powder. Also, the waste polyamide 12 powder is not graded before forming the recycled polyamide material.

Abstract: A method of forming a composite material includes disposing dried plant material, nanoparticles, and a supercritical fluid in a vessel. A cellular structure of the dried plant material expands when disposed in the supercritical fluid and the nanoparticles migrate into and are embedded within the expanded cellular structure of the disposed dried plant material. The disposed dried plant fibers with embedded nanoparticles are removed from the vessel and mixed with a polymer to form a polymer-nanoparticle mixture. A chemical additive can be added to the supercritical fluid and the chemical additive can remove at least one of hemicellulose, lignin and pectins from the dried plant material.

Abstract: A composite material is provided that includes a polymer matrix and fiber reinforcements within the polymer matrix, the fiber reinforcements including natural fibers having nanoparticles accumulated within a structure of the natural fibers. A method of forming the composite material is also provided that includes accumulating nanoparticles into the structure of the natural fibers to create accumulated natural fibers, drying the accumulated natural fibers, and mixing the accumulated natural fibers within the polymer matrix.

Abstract: A method of reducing aldehyde concentration in a vehicle cabin air, the method includes applying a solution comprising aldehyde scavenger(s) onto an outer surface of a foam article located or to be located within a vehicle cabin to form a top layer of the article such that aldehyde species are trapped within the article and prevented from being released into the cabin air.

Abstract: A method of forming a composite material includes immersing dried plant matter into an aqueous solution containing nanoparticles and applying a magnetic field and/or an electric field to the aqueous solution. A cellular structure of the dried plant matter expands when immersed in the aqueous solution and the nanoparticles migrate into and are embedded within the expanded cellular structure of the immersed dried plant matter. The method also includes removing at least one of hemicellulose, lignin and pectins from the dried plant matter by adding a chemical additive to the aqueous solution and/or wrapping or tagging the nanoparticles with a magnetic material such as nickel.
