  • Patent number: 10239281
    Abstract: A process to create composite preforms and parts by stacking layers of two-dimensional fiber material (e.g., fiber cloth, fiber reinforced fabric, etc.) having pin-receiving holes and/or gaps disposed between the fibers of the fiber material is described. The stack is pinned together using a subset of pins, such as fiber reinforcing pins, inserted into a subset of the pin receiving holes and/or gaps, leaving at least some of the pin receiving holes and/or gaps available for pinning other layers, as layers of fiber material are added to the stack. As additional layers are added to the stack, different subsets of pins connect the additional layers to the stack, thereby building up the stack. Each layer of fiber material may have a different shape than the other layers and any arbitrary topology, potentially including non-convex and/or disjoint shapes. Furthermore, implementations may produce composite preforms having an arbitrary number of interconnected layers.

  • Patent number: 8656676
    Abstract: A laminated, plate-shaped element with at least a first and a second substrate, which are joined together at least indirectly by adhesive bonding, and also with at least one support element associated with the first substrate to fasten the laminated element to an infrastructure and active position fastening of the second substrate at least in the event of failure of the bonded joint. The position fastening is active only between the first and second substrates and is placed a certain distance from the edge of the second substrate. The active position fastening is particularly applicable in laminated elements placed in an inclined or vertical mounting position, for example in solar modules with incorporated solar cells.

  • Patent number: 8574703
    Abstract: Disclosed is a method and apparatus for positioning and assembly of two or more parts wherein at least one of which is of a creep sensitive material. The method and apparatus enable very precise positioning of parts during assembly by holding a rough alignment with free play permitting finer alignment. Creep resistant annular inserts are molded into the part and provided with flow apertures to conduct plastic material into the annular insert bore. A spindle defined the geometry of a centering hole within the bore during molding. The annular inserts are operable as compression limiters to prevent deformation of the creep sensitive material under the action of heat or tightening stresses.

  • Publication number: 20130266793
    Abstract: A building panel incorporates blocks (11) of a low density material contained within a surrounding wire support cage (12). The cage is formed from a plurality of wire trusses (1) which are spaced apart such that each truss separates adjacent low density blocks, and the trusses are held together by strapping wires (14) which are encased within layers of render (15, 16) in use. The truss has opposing longitudinally extending reinforcing wires (2, 3) to which the strapping wires (14) are connected, and intermediate wires (4) which are preferably formed in a zig-zag. Each truss includes at least one additional wire (5) which extends longitudinally of the truss.

  • Patent number: 8551596
    Abstract: A self-sticking fabric structure includes loop-like fabric structure, which is fabricated by the yarns of the conjugate fiber and split thereafter to recover smaller fibers, substantially all of the fibers forming loop-like fastening elements between the intersection of interlacing or interlooping, and a hook fabric structure, which is fabricated by the yarns of staple fibers for enabling the ends of the staple fibers to protrude over the surface of the fabric and to form a layer of fiber flock type hook-like fastening elements. The fabrication of the self-sticking fabric does not require any further brushing or pile-raising processing process, saving the manufacturing cost, reducing the fabric thickness, and widening the application of the fabric.
