  • Patent number: 10401030
    Abstract: Components and methods for forming components are provided. For example, a method for forming a component includes laying up a plurality of plies to form a component preform that defines an axis of symmetry and a circumferential direction. Laying up the plurality of plies includes overlapping ends of the plurality of plies to define overlap regions and offsetting the overlap regions along the circumferential direction such that any radial line drawn from the axis of symmetry through the plies passes through only one overlap region. In another embodiment, a component includes a body that is symmetric about an axis of symmetry and that defines a circumferential direction and a radial direction. The body is formed from a plurality of plies and has a substantially uniform thickness. Ends of the plurality of plies are overlapped to define a plurality of overlap regions, which are offset along the circumferential direction.

  • Patent number: 10160136
    Abstract: A system and method for automated bending of wood strips. The system includes an preprogrammed automated robot arm that is fitted with a gripper for grasping and manipulating the wood board around a hot mandrel in order to bend the wood into intricate bent shapes. The wood strips are first soaked in water so that they pliable to bend around the mandrel. The heated mandrel plasticizes the lignin to allow the fibers to reorient in the wet wood strips thus fixing or locking the wood in the bent shape. The grippers are preferably pneumatic grippers formed from two plates that move towards each other to grasp or clamp onto the wood strip. A friction plate urges the wood strips against the heated mandrel to provide consistent and constant contact between the wood strip and the surface of the hated mandrel.

    Abstract: A process for manufacturing pipes using thermoplastic pipe and “tape” (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature tape is wrapped around the cold pipe in a dry environment. An external heat source is used to heat up the pipe causing the thermoplastic to melt and the pipe to expand due to thermal expansion. Since the fibers have less stretch than the thermal expansion of the pipe the fibers will be embedded into the molten layer of the pipe, creating a permanent bond between the fibers and the pipe. A protective film is applied to the pipe. Portions of the tape and film are scraped from the surface of the pipe creating an area where the end of the pipe is coupled to another pipe using an electronic fusion coupler.

  • Patent number: 8353316
    Abstract: A subsea flexible pipe, including an internal sealing sheath (18), at least one tensile pressure armor layer (14, 16) wound around the internal sealing sheath, a retaining layer (12) having at least one reinforcing strip (34), the reinforcing strip having filamentary strands (36) directed substantially longitudinally. The filamentary strands (36) having polymer fibers (38). The polymer fibers have, at room temperature, an elastic modulus in excess of 55 GPa so that the reinforcing strip is able to prevent radial expansion of the armor layer, when the armor layer experiences radial force; and the polymer fibers furthermore have an elongation at break in excess of 4% such that the reinforcing strip is able to undergo deformation without breaking.

  • Patent number: 8151392
    Abstract: A method for additionally conducting the hot air for finishing the articles of clothing (14) along the articles of clothing (14) in counterflow to the transporting direction (13). This leads to more effective finishing of the articles of clothing (14) with greater energy efficiency, and therefore the tunnel finisher according to the invention consumes less energy.

  • Patent number: 8084108
    Abstract: A core having enhanced ID stiffness is provided. The core includes inner, intermediate, and outer wall zones. The intermediate zone is spring-like in that it minimizes deformation of the inner zone from a radial deflection of the outer zone by absorbing at least some of the deformation. Similarly, the intermediate zone minimizes deformation of the outer zone from a radial deflection of the inner zone by absorbing at least some of the deformation. The intermediate zone includes at least first and second intermediate layers and one or more intermediate support layers. The first and second layers include a number of plies and gaps that are offset from each other, i.e. the plies of the first layer are radially aligned with the gaps of the second layer. The intermediate support layers are between the first and second layers and extend radially across the gaps of the first and second layers.

  • Publication number: 20110297270
    Abstract: The manufacture of clad tubes (30) is described. Tube (10) intended to line the walls of a combustion chamber is made of a high strength material to contain the high-pressure steam created. However, these tubes (10) are typically not corrosion/erosion resistant. Manufacture of tubes (10) with both high strength and high resistance to corrosion/erosion would be prohibitively expensive. Therefore, tubes (10) are covered with a non-corrosive material to protect them. This is done by surface welding a strip (20) of high alloy material to the outer surface (12) of the tubes (10). It is preferable to use electric high frequency resistance welding to surface weld the strip (20) onto tube (10). The strips (20) are preferably attached with little melting and metal dilution allowing the strip 20 to keep its corrosion/erosion resistance properties.

  • Patent number: 8066033
    Abstract: A spoolable composite tube capable of being spooled onto a reel for storage and for use in oil field applications. The spoolable tube exhibits unique anistropic characteristics that provide improved burst and collapse pressures, increased tensile strength, compression strength, and load carrying capacity, while still remaining sufficiently bendable to be spooled onto a reel in an open bore configuration. The spoolable composite tube can include an inner liner, an interface layer, fiber composite layers, a pressure barrier layer, and an outer protective layer. The fiber composite layers can have a unique triaxial braid structure.

  • Patent number: 8006722
    Abstract: A pipeline for conducting air for air conditioning in aircrafts includes a body portion formed with foamed plastics material or with a dense plastics material. The body portion defines a longitudinal axis and includes an outer surface carrying a wrapping for reinforcing the pipeline. The wrapping includes a plurality of adjacent contacting layers formed by at least one linear reinforcing element wound into a plurality of windings, with adjacent layers having windings angled in opposite directions to form a net-like structure of the wrapping. At least one of the spacing between the windings along the longitudinal axis or the angle of slope between the windings and the longitudinal axis varies in certain sections to change the winding density as a function of local mechanical load requirements on the pipeline.
