  • Publication number: 20150147560
    Abstract: A method for alignment of high aspect ratio materials (HARMs) within a liquid matrix by means of magnetic particles. The application of an external magnetic field creates a forced motion of the magnetic particles. This in turn leads to a laminar flow within the matrix which imposes a drag force on the HARMs, aligning the HARMs across the matrix. The used magnetic particles eventually accumulate at one end side of the matrix container and can be removed either by an incision or an extraction process. Unlike the previously proposed methods, there is no need for the magnetic particles to be attached either physically or chemically to the HARMs. Thus, the ultimate aligned HARMs are mostly pure and free of any magnetic particles. Once the matrix is a polymeric solution, the mentioned method is capable of synthesis of aligned HARMs-polymer composites, which exhibit improved mechanical and electrical properties.

  • Publication number: 20130136890
    Abstract: A prepreg that contains a plurality of unidirectionally aligned continuous fibers embedded within a thermoplastic polymer matrix is provided. In addition to continuous fibers, the prepreg also contains a plurality of long fibers that are combined with the continuous fibers so that they are randomly distributed within the thermoplastic matrix. As a result, at least a portion of the long fibers become oriented at an angle (e.g., perpendicular) relative to the direction of the continuous fibers. Through such orientation, the long fibers can substantially increase the mechanical properties of the prepreg in the transverse direction (e.g., strength) and thus achieve a more isotropic material. Although unique isotropic prepregs are one aspect of the present invention, it should be understood that this is not a requirement.

  • Publication number: 20130130583
    Abstract: A method includes a step of bringing a plastic matrix substance in contact with a reinforcement fiber structure to form an intermediate material. Further, the method includes a step of curing the matrix substance of the intermediate material to form a composite material. Before the plastic matrix substance is brought into contact with the reinforcement fiber structure, it is mixed with a diluent to form a mixture.

  • Publication number: 20130089700
    Abstract: A composite board having a sorghum stalk material component and a thermoplastic binder component is disclosed together with a corresponding method of manufacture. To prepare the composite board, the sorghum stalk material is harvested, dried and refined into fibers, particles or slit-stalks. In some cases, the stalk material is first combined with a thermosetting binder such PMDI. Next, the stalk material is arranged into one or more layers and then combined with a thermoplastic binder, such as HDPE film, in a stack. In some instances, recycled HDPE may be used. The stack is thermocompressed in a press at a preselected temperature to compress the sorghum and thermoplastic binder to a preselected board thickness. The board is then cooled to below the softening temperature of the thermoplastic resin. After cooling, the board can be cut or trimmed to its final desired dimensions.

  • Patent number: 8337979
    Abstract: The present invention provides methods for uniform growth of nanostructures such as nanotubes (e.g., carbon nanotubes) on the surface of a substrate, wherein the long axes of the nanostructures may be substantially aligned. The nanostructures may be further processed for use in various applications, such as composite materials. For example, a set of aligned nanostructures may be formed and transferred, either in bulk or to another surface, to another material to enhance the properties of the material. In some cases, the nanostructures may enhance the mechanical properties of a material, for example, providing mechanical reinforcement at an interface between two materials or plies. In some cases, the nanostructures may enhance thermal and/or electronic properties of a material. The present invention also provides systems and methods for growth of nanostructures, including batch processes and continuous processes.
