  • Publication number: 20100040816
    Abstract: The present invention provides silk fibre reinforced composite materials comprising a thermoplastic polymer matrix, which are relatively light, whilst having a high impact resistance. The silk fibre reinforced composite materials of the present invention allow for an optimal dissipation of the impact energy such that they have a penetration resistance higher than 20 J per mm of plate thickness, more preferably more than 30 J per mm, most preferably more than 40 J per mm. Due to the high impact resistance of the fibrous composite material according to the present invention, panels or shells comprising such composites are particularly useful for the manufacture of objects, which in the course of their life cycle are subject to shocks or at risk of penetration.

  • Publication number: 20100008990
    Abstract: The invention describes a new class of crystalline silica material having two levels of porosity and structural order. At the first level, building units are nanoslabs of uniform size having zeolite framework. At the second structural level, nanoslabs are assembled, e.g. linked through their corners, edges or faces following patterns imposed by interaction with cationic surfactant or triblock copolymer molecules. After evacuation of these molecules, microporosity is obtained inside the nanoslabs, and a precise mesoporosity between the nanoslabs depending on the tiling pattern of the zeolite nanoslabs, as evidenced by X-ray diffraction. These materials are useful for the fixation of biologically active species, such as poorly soluble drugs.

  • Patent number: 7520929
    Abstract: This invention consists of a modified gluten biopolymer for use in industrial applications, such as composites and foams. In the present work, the fracture toughness of the gluten polymer was improved with the addition of a thiol-containing modifying agent. This work also resulted in the development of a gluten biopolymer-modified fiber bundle, demonstrating the potential to process fully biodegradable composite materials. Qualitative analysis suggests that a reasonably strong interface between the natural fibers and biopolymer matrix can form spontaneously under the proper conditions. Therefore this invention relates to a modified gluten biopolymer for use in industrial applications, such as composites, stabilized foams and molded articles of manufactures. The present invention relates to a new gluten based biopolymer with modified properties, such as an increase in impact strength, and prepared by using thiol-containing molecules.
