Gilles Hochstetter has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8627713
    Abstract: The invention relates to a method for evaluating the fatigue life of a polymer composition, including the following steps: i) providing a polymer composition; ii) manufacturing a plurality of axisymmetric test tubes cut from said composition; iii) subjecting said test tubes to a uniaxial traction fatigue test including a plurality of loading and unloading cycles for the test tube, the geometry of the test tube making it possible to subject the material to triaxial stresses, in the area of the test tube cut, simulating the stress conditions for the pressure sheath of a flexible pipe, particularly for off-shore use; and iv) predetermining the number of cycles until the rupture of said polymer composition. The invention is related to the use of said polymer composition selected through the predetermining method for manufacturing pipes or conduits to convey a pressurized and/or corrosive fluid.

  • Publication number: 20110288194
    Abstract: One subject of the present invention is a composition that combines at least one polyamide having at least one MXD entity, MXD denoting meta-xylylenediamine or a mixture of meta-xylylenediamine and of para-xylylenediamine, with a bioresourced reinforcement. The invention also relates to the conversion of these compositions, by injection moulding or extrusion, into objects that have good mechanical properties, said objects corresponding to technical application specifications such as may be found, for example, in the automotive industry, construction, sport and in electrical or electronic fields.

  • Publication number: 20100189946
    Abstract: The invention relates to a composite material including nanotubes of a chemical element selected from the compounds of the elements of columns IIIa, IVa and Va of the periodic table, dispersed in a polymer matrix including (a) at least one fluorinated homo- or copolymer and (b) at least one fluorinated homo- or copolymer grafted with at least one carboxylic polar function. The invention also relates to the use of the composite material and to the use of at least one fluorinated homo- or copolymer grafted with at least one carboxylic polar function for increasing the tensile strength of a composite material containing the above nanotubes dispersed in a fluorinated polymer matrix.
