The method includes a step of cutting an intermediate reinforcing fiber layer (14a, 14b, 14c) after it has been applied, a step of withdrawing a cut portion prior to applying the following braided layer (14b, 14c), thereby locally building up an extra thickness of reinforcing layers on each portion of the cut layer that has remained in place, the extra thickness constituting local reinforcement of the part. Resin is subsequently injected into the various braided layers prior to the resin being polymerized in order to prepare a blank. The method applies in particular to the field of aviation.

  • Publication number: 20130029072
    Abstract: A reticular tubular structure formed by extruded filaments of synthetic plastic material extending in two oppositely tilted directions with respect to an axial direction of the tubular reticular structure. The filaments cross one another to form a tubular net of interconnected rhomboid meshes, vertices of the rhomboid meshes being formed by crossover points between two filaments fused together, while sides of the rhomboid meshes are formed by said filaments outside the crossover points. The tubular reticular structure is molecularly oriented in both longitudinal and transverse directions thereof, and is calendered so that the crossover points, at the vertices of the rhomboid meshes, and the filaments, at the sides thereof, have the same common thickness.

  • Publication number: 20120312848
    Abstract: A vehicle article carrier component and a method of manufacturing the component are disclosed. The method may involve forming a braided, tubular cylindrical form including a plurality of fibers having at least one of a curvilinear pattern or a helical pattern. A reinforcing form of unidirectionally oriented fibers may be positioned at a predetermined location on one of an interior or exterior surface of the braided tubular cylindrical form, to thus create a composite assembly. A resin may be used to saturate the composite assembly. An inflatable bladder and a molding tool may be used to form a finished, unitary composite part through a molding operation.

  • Patent number: 8323433
    Abstract: A method of making a corded surface flexible elastomer golf club grip. An underlist is extruded of seamless tubular uncured elastomer and a pattern of textile cords wound thereon. In one version of the method, an outer seamless tubular extruded uncured elastomer layer is assembled over the cord patterned underlist. A core rod is inserted in the underlist, an uncured elastomer cap assembled on the end and the assemblage cured in a heated compression mold. Upon removal from the mold, some material is removed from the outer surface to expose some of the cord. In another version, the uncured cord wound underlist with core rod is inserted in a mold cavity and a thin outer layer of elastomer injection molded thereover and the assemblage cured in the mold.

  • Publication number: 20120279635
    Abstract: The invention relates to a method of fabricating a composite material part in which one or more layers of braided, or woven, or indeed draped reinforcing fibers are applied onto a mandrel having the general shape of a body of revolution. After one or more layers have been applied onto the mandrel, an operation is performed of winding at least one tie helically around and along the assembly constituted by the mandrel and each layer of reinforcing fibers that it carries, so as to press each layer of reinforcing fibers against the mandrel. The invention relates to fabricating composite material parts such as beams, connecting rods, or arms made out of carbon fibers.

  • Patent number: 8241453
    Abstract: The object of the invention is a method for building hoses reinforced with spirally laid fibers, where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibers are unwound from drums (14). The drums (14) are rotated about two axes, the first axis being the principal axis of the drums (A) and the second axis (B) being nearly parallel with the direction in which the fibers are unwound, where the direction of rotation of the drums (14) about the second axis (B) is the same as the direction in which the hose under construction (3) is rotated.

    Abstract: A sleeve bearing assembly and method of construction therefor includes a woven inner portion bonded to an injection molded elastic outer portion. The inner portion includes a first yarn of lubricious yarn material and a second yarn of material that is different than the first yarn. The first yarn substantially provides an inner bearing surface and the second yarn substantially provides an outer surface that is bonded to the outer portion. The first and second yarns are woven together so that the first yarn is woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface to substantially provide the bearing surface and the second yarn is woven in a direction different than the first yarn to substantially provide the outer surface bonded to the outer portion.

  • Publication number: 20120111482
    Abstract: A catheter for diagnosing or treating the vessels found within a body or body space includes a center strut that is bonded, preferably thermally, along its longitudinal axis with the thermoplastic tubular member within which it is housed. The tubular member preferably has three layers: an inner layer, a braided layer and an outer layer. The composite catheter is made using a process in which two half-cylinder shaped mandrels are placed on each side of the center strut while the strut is heated in order to cause the thermal bonding. The bonded center strut provides in-plane deflection and improved transfer of torque to the tip of the catheter.

  • Publication number: 20120103502
    Abstract: In the field of aviation, a method of fabricating a composite-material rod. The method comprises a first step of fabricating a mandrel comprising a sleeve of composite material and solid inserts of composite material secured to the ends of said sleeve to constitute a rigid whole. Then, one or more layers of braided fibers are applied around the mandrel by using a fiber-braiding machine. Next, a resin is injected into the layers of braided fibers so as to establish cohesion rigidly bonding the braided fiber layers and at least the ends of the mandrel in order to form a rod body out of composite material having reinforced ends. Finally, respective holes are drilled at each end of the rod body, each hole passing through the layers of braided fibers and also through the corresponding insert.
