    摘要: A circular multi-wave composite compression spring (10) is formed from a carbon fiber (58) reinforced laminate. The circular compression spring (10) is comprised of unidirectional graphite fibers (58) encased in a polymeric resin of generally rectangular cross-section such that adjacent crests (14) and troughs (16) of the waves in adjacent turns (12) of the spring (10) contact each other along a radial line generally extending from the longitudinal axis (30) of the spring (10). The line contact provides for increased fatigue life and more stable loading of the spring (10) under compression. The carbon fiber reinforced laminate provides comparable strength characteristics similarly configured springs fabricated from conventional materials while providing significantly reduced weight. Furthermore, the composite spring (10) offers increased performance parameters such as increased linearity response over a wider spring deflection range and with insignificant hysteresis.

    摘要: A colored yarn is made in an inexpensive manner that allows a wide variety of different colors or hues within the product line, and also allows a wide variety of different effects to be produced including yarns with minimal leather effect, or yarns with a distinct and desired heather effect. A first coarse feeder yarn, e.g. a 1/1 semi worsted yarn, is ring or open end spun with about 2.5 turns per inch. The coarse feeder yarn is dyed, dried, and then cut and opened up into individual fibers about four inches long or less (preferably two inches long or less). The individual fibers are blended with differently colored or hued fibers produced in the same way, and/or with greige or colored staple fibers, to produce a blended composite of fibers. The blended composite is then spun, for example ring spun or open end spun, into a final colored yarn. Rayon fibers may especially effectively and uniquely be utilized, although almost any fiber or mix of fibers can be used.

    摘要: A joint between an at least hollow ended, generally cylindrical first component and a second component. The first component has a first end portion terminating in a first free end region, a second end portion terminating in a second free end region, and a mid portion extending between the first and second end portions. The mid portion has a first pre-determined external diameter and the first end portion has an external diameter which increases gradually from the first pre-determined external diameter to a second pre-determined external diameter at the first free end region. The first end portion is adapted to be pushed onto a tapered pin extending from the second component to a joined position. To insure transmission of rotational forces, in the joined position the first free end region of the first component extends into a generally ring-shaped socket in the second component, with the socket having at least one substantially planar circumferentially and axially extending surface against which a corresponding planar surface extending axially from the free end of the first free end region abuts.

    摘要: A stand-alone, crash-energy absorbing structure and fabrication method are provided. A plurality of adjoining rigid cells are each constructed of resin-cured fiber reinforcement and are arranged in a geometric configuration. The geometric configuration of cells is integrated by means of continuous fibers wrapped thereabout in order to maintain the cells in the geometric configuration. The cured part results in a net shape, stable structure that can function on its own with no additional reinforcement and can withstand combined loading while crushing in a desired direction.

    摘要: Spiral bands having a plurality of convolutions of a high tensile strength composite material are formed by feeding a plurality of continuous high tensile strength fibers through an uncured resin to form a web, depositing the web on a release web having at least one substantially flat surface to form a laminate, winding the laminate around the mandrel to form a plurality of overlapping convolutions, curing the resin in the composite web to set the convolutions in a spiral configuration, and then removing the release web from the composite web. The convolutions of the spiral bands in accordance with this process have substantially flat surfaces and an elastic memory. These bands can be used to reinforce axially extending structures having internal forces directed radially outward therefrom by wrapping the band around the structure with a layer of adhesive applied to hold the convolutions in place.

    摘要: Fiber-reinforced composite springs having a unidirectional fiber wind. The present invention is a cylindrical torsion bar, or a helical tension or compression spring having a core that is either unreinforced, axial-fiber reinforced, or twisted fiber-reinforced, and a continuous-fiber-reinforced composite cladding having most or all of its fibers helically arrayed around the core. The core may be solid or hollow. The sense of the helical winding is that which places the fibers in tension when the spring is used as intended. A cladding fiber winding helix angle of approximately 55.degree. is used with a weak and unreinforced core, while larger or smaller helix angles are used only with a cores having sufficient stiffness to resist axial-normal stress. By carefully selecting the materials for the core and cladding, as well as utilizing a core twist and a fiber winding helix angle appropriate to the application, significant advantages over prior art springs are realized in energy per-unit-volume, energy per-unit-weight, and spring velocity.

    摘要: In a vehicle having a chassis, an axle and a pair of laterally spaced torque arm assemblies connecting the axle to the chassis and arranged longitudinally of the vehicle, each torque arm assembly includes a composite resin/glass fiber arm which has one end pivotally attached to the a chassis and which is attached to the axle at a first bolt by an end fitting. A clamp assembly is clamped to the arm along a length of the arm spaced from the end fitting and is fastened to the axle at a second bolt spaced from the first bolt. Cushioning between the clamp assembly and the arm is provided by rubber pads. The two torque arm assemblies produce an anti-roll effect by the bending of each arm in opposite directions during cornering or traversing uneven surfaces.

    摘要: An energy absorbing device, suitable for use in the leg structure of aircraft passenger seating for the purpose of attenuating crash forces, having first and second attachment fittings 11, 21 with a tube 10 of fiber reinforced plastics material extending between them. Tube 10 has a crush initiation band 17 at which buckling of the tube commences upon compressive overload. Long, tough fibers are used as the reinforcing material in the tube so that, when compression of the device has concluded, there is a residual tensile capability. Successful operation of the device is facilitated by providing attachment fitting 12 with a slider 15 which helps to maintain the collapsing portion of the tube in axial alignment with the uncollapsed portion. The slider also acts as a tube wall straightener to unbuckle the collapsed fibers when tensile load is applied.
