  • Patent number: 9694441
    Abstract: The invention relates to a planar structure for joining, in particular for the material-uniting joining, of at least two components. According to the invention, the planar structure is flexible and formed by at least one reaction strand. The reaction strand comprises a preferably cylindrical core, which is provided, at least in some areas, with a coating, which is constructed with a plurality of coaxially applied layers with a small thickness. To produce the layers, two different materials are used, the layers being constructed alternately with one of the two materials. Because of the high degree of flexibility of the reactive planar structure and its arbitrary area extent, components with a complex geometry in the region of the joint faces as well as large-format components can be joined in a material-uniting manner without problems.

    Abstract: A composite spacer operable to be mounted on a first component is disclosed herein, wherein compression loads associated with attaching the first component to some other structure are born by the composite spacer to limit compressive deformation of the first component. The composite spacer includes a first body formed of resin and defining an aperture extending along an axis. The composite spacer also includes a plurality of first fibers positioned in the first body about the aperture. Each of the first fibers extends substantially parallel to the axis and increases a compressive strength of the first body relative to the axial direction.

  • Publication number: 20090323196
    Abstract: The present invention provides a clad glass composition that is excellent in devitrification resistance and that prevents the whole mother glass rod from devitrifying by preventing a core glass composition from devitrifying in forming a mother glass rod using a concentric crucible drawing method. The clad glass composition forms a clad of a mother glass rod for a gradient-index rod lens having a core/clad structure. The clad glass composition includes the following components, indicated by mol %: 45 to 65% SiO2; 0.5 to 10% TiO2; 0 to 15% B2O3; 0 to 7% Al2O3; 0.1 to 10% Bi2O3; 0 to 5% Li2O; 5 to 30% Na2O; 0 to 10% K2O; 0 to 15% MgO; 0 to 10% CaO; 0 to 10% SrO; 0.
