  • Publication number: 20140272324
    Abstract: Novel methods and kits for creating defects in composite materials, as well as an engineered part or structure with one or more designed defects, are disclosed. The disclosed inventions advantageously permit the intentional introduction of one or multiple defects of any desired size and shape, either between the same two chosen laminae or on different layers within a multi-layer composite, having mechanical and thermal properties that are akin to those found for actual defects. One disclosed method involves creating a mask having a cut-out in the size and shape of a desired defect, placing the mask at a location on a first substrate where the defect is desired, applying a release agent, removing the mask, and adding a second substrate over the first substrate with release agent. The first substrate may be a cured lamina or an uncured lamina pre-impregnated with resin having a barricade in the size and shape of the outline of the desired defect.

  • Patent number: 8309190
    Abstract: The invention relates to an article formed by a rotational molding process, having at least one layer formed from a high molecular weight polyamide. The high molecular weight polyamide is one having a molecular weight in the range of 20,000 to 35,000 and also having an inherent viscosity of 1.05-1.60 dL/g. Rotomolded articles having a high molecular weight polyamide layer have better low-temperature impact performance compared to articles formed from lower molecular weight polyamides.

  • Publication number: 20110259544
    Abstract: Provided are apparatus and methods for storing thermal energy. For example, an apparatus including comprising at least one phase change material, and a capsule containing the at least one phase change material. The capsule may be permanently or temporarily sealed to contain the encapsulation material. The encapsulation material includes at least one material that is chemically and physically distinct from the phase change material. The encapsulation material and phase change material are selected to store and discharge thermal energy at temperatures of greater than 400° C. without capsule failure.

  • Patent number: 6615559
    Abstract: A resiliently flexible construction beam includes a pair of lateral flange portions and a web extending therebetween, preferably, but not necessarily, so as to present a cross-sectional profile corresponding to commonly used construction beam members (e.g., 2″×4″ or 2″×6″). The resilience of the beam helps to attenuate sound transmission through the beam from one lateral member to the other. In particular, in a wall frame, beams according to the present invention are mounted at opposite ends thereof to end plates. In one example, the end plates include slits into which the webs of the beams can be received. The resilient web according to the present invention is conveniently made from a unitary piece of material such as, for example, steel.

  • Patent number: 6500539
    Abstract: A unique fabric with non-adherent characteristics making it suitable for use as a wound dressing, and particularly as a dressing for burns, is disclosed The fabric comprises cellulose acetate fibers and a siloxane finishing on the fibers. In a preferred embodiment, the dressing comprises cellulose acetate fibers, cellulose acetate fiber having an anti-biologic incorporated into the fiber resin, and a siloxane finishing on the fibers. The fabric of the invention was found to be less adherent to burns than dressings made from cotton or having a nylon net about an absorbent pad.
