  • Patent number: 7104210
    Abstract: A sailcloth in roll good form permits efficient and cost effective construction of cross cut and vertical cut, laminate sails based on “off-angle,” (assymetrical) load bearing fibers. The sailcloth also may include a conventional warp and fill thread or fiber layout. Such sailcloth illustratively is significantly less susceptible to load force stretch, creep elongation, and airfoil shape deformation because, among other things, it is not dependent on the load bearing limitations of symmetrical, woven or knitted roll good sailcloth.

  • Patent number: 7041357
    Abstract: Apparatus and methods are presented for reinforcing and stiffening a printed circuit board (PCB) in selected locations by utilizing preferentially oriented fibers. Selected fibers within the polymeric material matrix of the PCB fiber-matrix layer are removed and replaced with a similar quantity of fibers in a preferential orientation. Various combinations of layering of modified fiber-matrix layer material with conventional fiber-matrix layer material are presented to achieve the desired PCB stiffening. Printed circuit boards, under the weight of heavy attached electronic components, may deflect or flex along an axis, defined as the characteristic fold. This flexing is exasperated with manufacturing and handling loading, particularly when mounted in a chassis. Preferentially orientated fibers laid transverse to the characteristic fold reinforces the area to resist flexure within the area surrounding the characteristic fold.

  • Patent number: 7011731
    Abstract: Provided is a method for manufacturing a papermaking belt structure using tapes made of a solid thermoplastic resin surrounding a fibrous matrix. The method calls for applying a layer of CD oriented tapes to a mandrel surface, then applying a layer of MD oriented tapes over the CD layer, applying pressure and heat to the mandrel containing the CD and MD layers so to melt the resin and entirely bond/encapsulate the fibrous matrix. The belt structure thus obtained may thereafter be grooved, drilled or other processed as desired. Additionally, the above method can be reversed as to the MD/CD order of layering. Also, a layer entirely of resin can be applied, preferably prior to, but also after or in between the MD/CD layers. Also, rubber can comprise one or more layers.
