  • Patent number: 10036164
    Abstract: Matrix basalt reinforcing members for concrete. The basalt members are specifically formed to provide tension support having a beneficial use with pervious concrete used in large areas such as sidewalk and parking lot. The basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable of supporting heavy loads such as trucks without cracking while allowing water to pass through the concrete. The basalt reinforcing members are formed from roving crosses and interlaces in between each side of the figure 8 shape to mitigate potential for sheer at crossovers.

  • Patent number: 8313600
    Abstract: A method and system for fabricating a geometrically versatile composite lattice support structure having a seamless three-dimensional configuration. The lattice support structure is created by forming two or more cross supports, such as helical, longitudinal, circumferential and/or lateral cross supports, which intersect to form a plurality of multi-layered nodes. The lattice support structure may be designed without any protrusions extending outward from the overall geometry, thus enabling efficient tooling, and thus enabling ease of mass production. The lattice support structure may comprise a completely circumferentially closed geometry, such as a cylinder, ellipse, airfoil, etc. The method for fabricating the lattice support structure comprises laying up a fiber material, in the presence of resin, within rigid channels of a rigid mold, thus creating a green, uncured three-dimensional geometry of unconsolidated cross supports and multi-layered nodes where these intersect.

An expansion block is placed in each of the cavities, and is held in place by an elastomeric contact adhesive having adhesive properties that are substantially diminished when the adhesive is heated to an elevated curing temperature. The assembly is then autoclave cured. After cooling, the formed structure is separated from the base tool and the expansion blocks are removed from the cavities. A grid-stiffened sandwich structure is formed by applying an outer skin over the ribs and expansion blocks, before curing the assembly. After cooling, the outer skin is removed to allow extraction of the blocks, and subsequently bonded to the ribs.

  • Patent number: 8177933
    Abstract: A first insert (15) forming a ring is placed inside and in contact with a core (10) in degradable material. On the outer face of the core a plurality of inserts (20) is arranged each comprising a platform (21) applied against the outer face of the core and at least one blade (22) extending substantially radially outwards. A fibrous structure (56) is wound around the core passing over the platforms (21) and over the inner surface of the ring-shaped insert (15). Molding of the fibrous structure, impregnated with a composition containing a resin, is performed before polymerization of the resin and removal of the core.

  • Patent number: 8123888
    Abstract: A technique facilitates construction of high temperature fiber reinforced polymer oilfield tubulars. The technique comprises a method of combining a fiber material and a high temperature thermoset resin to create a high performance composite material. The composite material is formed into an oilfield tubular that can be used in a variety of downhole applications. The method of combining the high performance materials with low modulus, high temperature coating materials during the manufacturing process produces composite tubular products that can survive prolonged exposure to deleterious well fluids in high temperature and high pressure downhole environments.
