  • Publication number: 20140158285
    Abstract: Structural members having enhanced load bearing capacity per unit mass include a skeleton structure formed from strips of material. Notches may be placed on the strips and a weave of tensile material placed in the notches and woven around the skeleton structure. At least one pair of structural members can be jointed together to provide very strong joints due to a weave patterns of tensile material, such as Kevlar, that distributes stress throughout the structure, preventing stress from concentrating in one area. Methods of manufacturing such structural members include molding material into skeletons of desired cross section using a matrix of molding segments. Total catastrophic failures in composite materials are substantially avoided and the strength to weight ratio of structures can be increased.

    Abstract: Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products.

    Abstract: A method of forming a textile fabric using a frame (20) which has pegs (22) spaced apart around the perimeter with yarn wound a first direction (26) between parallel pegs forming a warp. Yarn is then wound a second direction (28) 90-degrees from the first directly on top creating a woof-like layer, but not interlaced. Yarn is crocheted in a chain stitch a first (30) and a second (32) diagonal or right-angled direction across the frame tying the warp and woof layers together into a fabric. Yarn is finally crocheted in a chain stitch through the perimeter of the textile joining the edges together into interlocked loops that will not unravel. The fabric is then removed from each peg by pulling the yarn upwardly off the peg by means of a crochet hook.

  • Patent number: 4081885
    Abstract: A method of making a textile product. In the preferred form a rectangular loom is utilized. The strands of string are applied transversely between opposite sides of the loom forming a gridlike backing web. Then yarns which may be colored are extended transversely between opposite sides of the loom in alignment with the strands of the web. From the opposite side of the web, as formed, the intersections of the strands of string and overlying yarns are secured together by being tied preferably by way of clove hitches. Then an implement in the form of a stiff member is passed between backing web and adjacent runs of yarn and then yarns that are transverse to the said member are cut midway between the intersections. All the yarns are cut in this way. Cut yarns then form rosettes. The ends of transverse strings are then tied to hold the rosettes at the ends in place and fringes or tassles may be formed along the edges of the articles after removal from the loom.
