  • Patent number: 9718932
    Abstract: A process is provided for overmolding an insert or substrate with non-oriented thermoplastic fibers present in an amount that allows them to thermally bond in the presence of non-oriented filler fibers. The thermoplastic fiber fusion retains the filler fibers within the insert upon cooling. The filler fibers are selected to modify the properties of the insert and an overmolded article formed with the insert therein. Such overmolded articles are used in applications including vehicle components such as automotive interior light bases, posts, undercar components, cross members, chassis components, and frame components; architectural components such as home door interiors, sound damping panels, and weather resistant wood replacement. Articles formed with the inventive process yield weight reductions compared to conventional insert overmoldings, along with low scrap generation, process flexibility with respect to part shape and fiber material.

  • Publication number: 20150033983
    Abstract: Building materials are generated by the simple mixing of cellulose nanofiber (CNF) slurry with typical wood-derived material such as wood meal, optionally with mineral particulate materials, and dried. Particle boards are made with wood meal particulates; wallboards are made with wood particulates and mineral particulates; paints are made with pigment particulates; and cement is made with aggregate particulates. The particle board samples were tested for fracture toughness. The fracture toughness was found to be from 20% higher up to ten times higher than the typical value for similar board, depending on the formulation. For cases of 20% by weight cellulose nanofibers and 80% wood, the fracture toughness was more than double that of typical particle board. The process sequesters carbon and oxygen into the building product for its lifespan—typically decades—and avoid releasing CO2 into the atmosphere.

  • Patent number: 8318618
    Abstract: A mat having a highly uniform porosity distribution is produced by consolidating 15 or more layers of melt blown webs (or the like) having different orientations. Control over the porosity is provided by using webs that exhibit a narrow, unimodal distribution of fiber diameters over the bulk of its distribution, such as in the top 80%. A compliance of the mats can be chosen by selecting a number and orientation of the webs. It is thus possible to produce mats that are good candidates for vascular grafts, for example. The uniformity of the porosity within the range of 6 ?m to 30 ?m permits seeding of the vascular graft with endothelial and smooth muscle cells. The mats have the demonstrated ability to retain, and support growth of, smooth muscle cells and endothelial cells.

  • Patent number: 8273201
    Abstract: A fiber mixture of natural fibers and binder fibers are blown from a storage container onto a first transport belt with a three-dimensional alignment of the fibers resulting in a fiber fleece. Thermally activatable synthetic resin granules are blown onto the fiber fleece and the fleece is defibered and remixed. The remixed fiber mixture is blown onto a second transport belt with a three-dimensional alignment of the fibers resulting in a mat. The thickness of the mat is obtained by the circulating speed of the second transport belt. The mat is transferred to an oven belt and is moved through a heating/cooling oven, for softening of the binder fibers and the synthetic resin granules, resulting in an intimate bonding of the wood fibers, the binder fibers, and the synthetic resin granules. The final thickness and the bulk density are set to specified ranges.

  • Publication number: 20120040461
    Abstract: Disclosed are composite arrays and methods of forming the arrays. Composite arrays include a hydrogel-forming polymeric network and a network of electrospun fibers embedded within the polymeric network. For instance, the polymeric network can include one or more extracellular matrix proteins. The network of electrospun fibers can describe an open configuration that incorporates sufficient space between adjacent fibers to allow for cellular ingrowth between and among individual fibers. Disclosed composite arrays can be utilized as a supporting scaffold for living cells, for instance in development of bioengineered tissue constructs.

  • Publication number: 20110308694
    Abstract: The process described herein presents a unique method and means of manufacturing medium density fibreboard (MDF) using agricultural plant stalks. The plant stalks are first depithed. The stalks are then broken down into fiber-like threads and made into fiber bundles. These fiber bundles are then combined with a resin component and a wax component, and the resulting mixture is cured. The MDF is economical to manufacture than prior art fibreboard in that it does not necessitate the use of expensive MDI resin. Further, the fibreboard is environmentally friendly in that it provides a beneficial use for agricultural waste.

  • Patent number: 8057614
    Abstract: A method of forming a molding mat formed bundles of reinforcing fibers and bonding materials is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The bonding materials may be any thermosetting material having a melting point less than the reinforcing fiber. The molding mat may be formed by partially opening the wet use chopped strand glass fibers and filamentizing the bonding materials, blending the reinforcement and bonding fibers, forming the reinforcement and bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the bonding fibers but below the temperature of the glass fibers. The molding mat thus formed may be used as a reinforcement material in sheet molding compounds.
