  • Patent number: 10479031
    Abstract: The invention relates to a method and a device for infiltrating a fiber preform of a component of fiber composite material with a matrix material. On the method side, it is proposed that an elastic coating (3) is applied onto the fiber preform (1, 23, 37), wherein the elastic coating (3) is widened to form a gap space (22) between the fiber preform (1) and the coating (3). The matrix material (21) is then fed into the gap space (22) and the elastic coating (3) is subsequently pressed against the fiber preform (1, 23, 37). On the device side, it is claimed that an elastic coating (3) is arranged on the fiber preform (1, 23, 37) and means are provided, which are in operative connection with the elastic coating (3), by which the coating (3) can be widened while forming a gap space (22) between the fiber preform (1, 23, 37) and the coating (3). A matrix material (21) can be fed into the gap space (22) and the coating (3) can be pressed against the fiber preform (1, 23, 37).

  • Patent number: 10226601
    Abstract: A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. The length of the fibers of the second group varies progressively in accordance to their proximity to the fibers of the first group; the fibers of the second group closest to the fibers of the first group being longer than the fibers of the second group further from the fibers of the first group. The fiber of the second fiber layer winds circumferentially around the longitudinal axis of the balloon substantially over the entire length of the balloon.

  • Patent number: 10030793
    Abstract: To produce a flexible pipe body, a length of tensile armour element (300) of pre-preg composite material is fed towards a fluid-retaining layer (602). The tensile armour element (300) passes through a guide (604) an a pre-heater (606). The tensile armour element (300) is then applied to the fluid-retaining layer (602), being wrapped around the fluid-etaining layer (602) by virtue of the rotation of the layer (602), the linear translation of the layer (602), and the fixed position of the tensile armour element feed (601). The element (300) is fed to the fluid-retaining layer under a constant, predetermined controlled tension. Positioning head (608) helps to position the element (300) on the fluid-retaining layer (602). As tensile armour element is wound onto the pipe body, the pipe body continues to move in a, linear direction and the pipe body moves through an oven (610).

The method calls for the use of continuous filament high modulus yarns in a braided structure, pressurizing the balloon, inserting the pressurized balloon inside the braided structure, applying axial tension on the braid, thus causing the braided structure to collapse onto and conform to the shape of the pressurized balloon and bonding the reinforcement braid yarns to the exterior surface of the pressurized balloon.

  • Patent number: 7799160
    Abstract: The present invention relates to a method for manufacturing a composite container with different opening sizes, which is accomplished by winding with fibers impregnated with resin. First, fibers impregnated with resin are wound on a first substrate for winding a first container, wherein first openings are positioned at both ends of the first container. Then, cut the first container into two shells with a first opening each, and slip one of the shells on a second substrate. Next, fibers impregnated with resin is used for winding the second substrate and the shell such that the fibers impregnated with resin wound on the second substrate and the shell are combined to form a second container, where both ends of the second container are the first opening and a second opening with different opening sizes. Thereby, filament winding can be applied for manufacturing containers with different opening sizes on both ends, and the technique of manufacturing and performance of containers are enhanced.

  • Patent number: 7479201
    Abstract: A method for fabricating a grid-stiffened structure from fiber-reinforced composite materials. Ribs are formed on a smooth hard base tool. Expansion blocks are placed in the shallow cavities formed by the ribs and the base tool, and held in place by a synthetic elastomer-based adhesive while a skin is placed over the ribs, expansion blocks, and base tool. The assembly is then placed in a vacuum bag and autoclave cured. After cooling, the expansion blocks are removed and the formed structure is removed from the hard base tool. This abstract is provided to comply with the rules requiring an abstract, and is intended to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 7384492
    Abstract: The present invention provides a method of forming hybrid and composite filters, which are more durable than that of the prior art. The method of forming a hybrid tubular filter includes wrapping a first layer of fiber, wrapping a filtering material and then wrapping a second layer of fiber. A mandrel is retained in a lathe chuck or the like and an end of fiber is attached to the mandrel. A fiber guide moves parallel to a length of the mandrel according to the direction of a control device. The method of forming a composite tubular filter includes wrapping a first layer of fiber around a mandrel.

  • Patent number: 6835263
    Abstract: An undercritical drive shaft and a method of producing the undercritical drive shaft from fiber composite material is disclosed. The drive shaft, which is produced of fiber composite material and is to be used as an undercritically operating shaft, has a high damage tolerance with respect to resistance to torsion and the manufacturing process requires lower expenditures. For the drive shaft, the fiber composite material consists of several successively individually wound-up webs of prepreg. For the method of producing the drive shaft from fiber composite material, as the fiber material, the web-shaped prepreg is wound onto the winding spindle and this prepreg is deaerated and simultaneously compressed by the winding-on of a thermoplastic woven band which is prestressed in a defined manner. The thermoplastic woven band is unwound again and additional prepreg layers are then wound up which are then deaerated and compressed in the same manner by a thermoplastic woven band.

  • Publication number: 20040211508
    Abstract: A method for the production of curved thread-reinforced tubular structures composed of rubber layers and of strengthening layers and an accompanying device. In one aspect, the method includes the application of a first rubber layer to the circumference of mandrels driven forward in a feed direction (X) and winding on of a multiplicity of parallel reinforcing threads, having defined thread angles (&agr;) with respect to the feed axis (x), by means of a bobbin creel, to form a first thread ply. The mandrels are led through a rotating deflection element surrounding the mandrels and the reinforcing threads are guided so as to be distributed on the inner circumference. An application of a covering rubber layer may be performed (after the optionally multiple execution of the previous steps, alone or in combination). The mandrels are led through the deflection element of the bobbin creel eccentrically in the region of the deflection element.
