  • Patent number: 9809001
    Abstract: Flexural digital materials are discrete parts that can be assembled into a lattice structure to produce an actuatable structure capable of coordinated reversible spatially-distributed deformation. The structure comprises a set of discrete flexural digital material units assembled according to a lattice geometry, with a majority of the discrete units being connected, or adapted to be connected, to at least two other units according to the geometry. In response to certain types of loading of the structure, a coordinated reversible spatially-distributed deformation of at least part of the structure occurs. The deformation of the structure is due to the shape or material composition of the discrete units, the configuration of connections between the units, and/or the configuration of the lattice geometry. Exemplary types of such actuatable structures include airplane wing sections and robotic leg structures.

  • Patent number: 9803415
    Abstract: A flexible spacer body has two opposing faces adapted to engage the inner surfaces of glazing structures to define an insulating glazing unit. The spacer body may be desiccated polymeric foam such as a silicone foam rubber or EPDM. An adhesive capable of bonding the spacer body to the glazing structure is carried by both of the faces. The adhesive may be from about 0.050 mm to about 1.524 mm thick. The adhesive material also has the properties of low argon gas and low moisture permeability. The adhesive comprises polymers where butyl rubber and/or polyisobutylene polymers together make up the majority of the polymers. The adhesive may also comprise other materials as needed to make it pressure sensitive and to impart a water resistant bond to glass glazing structures. The space assembly may include additional materials to secure the adhesive to the spacer body.

  • Patent number: 9776373
    Abstract: The invention relates to a method for bending at least one edge of a composite sheet, which has at least two outer metallic layers and an inner plastic layer, in which the edge of the composite sheet is edge-bent in a first step and is bent into the finished form in at least one further method step. In addition, the invention relates to a correspondingly bent composite sheet. The object of making a method for bending a composite sheet available, in which cracks in the metallic layers of the composite sheet can be prevented and, at the same time, in which a seam can easily be provided, is achieved by using an edge-bending punch, a holding-down device and an edge-bending jaw during the edge-bending operation and by the edge-bending punch having a notch running in the bending direction below the bending edge of the edge-bending punch.

  • Patent number: 9738054
    Abstract: Provided are assemblies, each including a first structure having a uniform coefficient of thermal expansion (CTE) and a second composite structure having a variable CTE. Also provided are methods of forming such assemblies. The second structure has overlap, transition, and baseline regions. The overlap region directly interfaces the first structure and has a CTE comparable to that of the first structure. The baseline region is away from the first structure and has a different CTE. Each of these CTEs may be uniform in its respective region. The transition region may interconnect the baseline and overlap regions and may have gradual CTE change from one end to the other. The CTE variation with the second composite structure may be achieved by changing fiber angles in at least one ply extending through all three regions. For example, any of the plies may be subjected to fiber steering.

  • Patent number: 9738055
    Abstract: A fiber reinforced composite, a component for a wind turbine and a method for manufacturing a component for a wind turbine are provided. The fiber reinforced composite includes a plurality of first fibers, the first fibers being arranged in a unidirectional or biax-configuration, a plurality of second fibers, the second fibers being arranged perpendicularly with respect to a lengthwise direction of the first fibers, and a resin impregnating the first and second fibers, wherein a E-modulus of the resin equals an E-modulus of the second fibers. Since the E-modulus of the resin and the E-modulus of the second fibers are equal, an early initiation of fatigue cracks is avoided.

  • Patent number: 9731472
    Abstract: The plurality of pieces of low density cellular material, such as foam plastics, form a core panel having opposite side surfaces and with adjacent pieces having opposing edge surfaces extending between the side surfaces. Sheets of flexible material, such as veils or mats or scrim, are adhesively attached to the side surfaces, and portions of one sheet extend between the opposing adjacent edge surfaces for limiting flexing of the panel. The pieces may be tapered, and portions of the one sheet may project between the edge surfaces either partially or fully to form double wall webs. The webs may have flanges adhesively attached to the other sheet on the opposite side. One sheet may also be stretchable in areas not adhesively attached to the pieces to provide for curving the panel from a planar position maintained by the sheet on the opposite side.

  • Patent number: 9724895
    Abstract: A composite laminate includes two composite layers, at least one metal mesh of high strength and high capability of absorbing impact energy, and multiple unidirectional fibrous layers, wherein the metal mesh and the unidirectional fibrous layers are disposed between the two composite layers. By adding the metal mesh to a composite laminate for making parts, such as front forks, frames, and seat posts of bicycles, an interlocking structure can be formed in the composite laminate. Due to the metal mesh having high strength and toughness, a part being formed of the composite laminate will have a high strength and an enhanced impact resisting capacity and thus can be prevented from brittle fracture. Furthermore, with the metal-reinforced composite laminate, a failure of the part can be warned at an earlier time, so that the part can be prevented from catastrophic damages, thus ensuring safety for users.

  • Patent number: 9718252
    Abstract: A component (34A, 34B, 34C) has a core formed of a stack (25, 36) of sheets (20) of material with cutouts (22A) aligned to form passages (38) in the core. An outer casing (29) spans the stack axially (51), brackets at least parts of opposed ends of the stack, and holds the sheets together in axial compression (46). Respective cooperating elements (30, 31) on the casing and the stack may register the casing with respect to the stack. Pins (24) in some sheets may engage holes (23) in adjacent sheets to register the sheets with each other. The casing may be segmented (28A, 28B, 28C). A hoop (66) may be compressed around the segmented casing. A gas turbine fuel injector may be formed of a stack (36) with an inlet element (44) compressed (46) onto the stack by the casing (29).
