  • Patent number: 10648481
    Abstract: A spacer of a gas turbine engine is reinforced with a fiber. The fiber can be cured with a substrate to form a fiber reinforced composite material. As a gas turbine engine operates, the rotation creates forces which can deform, expand, contract or translate certain gas turbine engine components, including spacers. These forces can adversely affect gas turbine engine performance and reliability, particularly when they are either unpredictable or difficult to control. Reinforcing a spacer with a fiber may allow a lower system weight, more compact or configurable internal packaging or a high degree of reinforcement.

  • Publication number: 20150129115
    Abstract: Some embodiments relate to three-dimensional molds and methods of forming such molds. A mold can be prepared by combining three-dimensional molds together. Then, a composite material, such as carbon fiber wetted with epoxy or another reinforcement material, is inserted into column gaps and beam holes in the mold. A joint region can be formed by extending the composite material beyond corner combining elements to reach to another edge combining element, which may prevent the necessity of an additional bonding or joining part. A coating part can enclose the composite material in the mold. The mold can be placed into a vacuum bag for vacuuming processing and bonding of the gaps of the composite material (e.g., carbon fiber) with each other and gaps in the mold. A heat treatment can be performed in a furnace. The product can be extracted by melting the mold in which the product is shaped.

  • Publication number: 20150094409
    Abstract: Fiber composites are disclosed that have flame-resistant properties. The fiber composites can contain relatively long fibers having a fiber length of greater than 3 mm. The composites, in one embodiment, can be formed through a pultrusion process to produce continuous structures or pellets having a length of greater than 3 mm. The pellets can then be used to mold articles. In accordance with the present disclosure, the flame retardant composition contains a nitrogen and phosphorus compound, such as a pyrophosphate. The flame retardant is intumescent and can be halogen-free. The flame retardant composition can also be free of any flame suppressant.

  • Patent number: 8986583
    Abstract: The invention relates to a pultrusion process in which a continuous reinforcement profile is formed by canting of at least one prepreg strip composed of a fiber-reinforced plastics material. The first shaping of the profile takes place in a preform device, which is downstream of a pressure-molding device for final shaping and prehardening. The movement of the profile takes place synchronously with respect to the operating cycle of the pressure-molding device by means of a traction device. By using a cutting device, it is possible to cut the profile to length and/or to subject edges to subsequent mechanical operations to ensure that correct dimensions are maintained. A continuous (pultrusion) gusset is inserted between the prepreg strips in a radius region of the profile. The gusset has an approximately triangular cross sectional geometry and it is formed by a plurality of continuous fibers braided with one another.

  • Publication number: 20140367031
    Abstract: The invention relates to a method for depositing one- or two-dimensional fiber structures in order to form a two- or three-dimensional fiber structure, in particular a fiber structure in the form of a fiber-reinforced plastic (FRP) or FRP semi-finished product, using a production machine including at least one depositing device and at least one fiber support. The one- or two-dimensional fiber structures have at least one unidirectional fiber layer. The depositing device deposits the one- or two-dimensional fiber structures onto the fiber support in a depositing direction in a controlled manner such that the fiber directions of the deposited one- or two-dimensional fiber structures assume an angle ?>20°, preferably ?>60°, and a maximum of ?=90°, relative to the depositing direction. The one- or two-dimensional fiber structures are deposited on the fiber support in a substantially tension-free manner with respect to the fiber direction of the fiber structures.
