David Verlin Cunningham has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Densely woven quasi-unidirectional fabric for ballistic applications
    Patent number: 7820565
    Abstract: A fabric including a first layer of high-performance unidirectional yarns and a second layer of high-performance unidirectional yarns disposed transversely to the first layer. The fabric also includes warp and fill encapsulating yarns woven around the unidirectional yarns to substantially stabilize the unidirectional yarns. The encapsulating yarns have tenacities and tensile moduli substantially less than the tenacities and tensile moduli of the unidirectional yarns. The fabric has a cover factor between approximately 0.75 and approximately 1.50.

  • Unique ballistic composition
    Patent number: 7407900
    Abstract: A ballistic composite comprises multiple layers of a fabric having unidirectional ballistic resistant yarns in at least two layers and a resin layer between each pair of such multiple layers adhered to the ballistic resistant yarns but not encapsulation the same and not penetrating the layer of fabric. The ballistic yarn layers are at 90°±5° with respect to each other and the ballistic resistant yarns are stabilized by being woven in a second fabric. The second fabric is formed of yarns having a substantially lower tenacity and tensile modulus than the ballistic resistant yarn. The ballistic resistant yarns have a tenacity of at least about 15 grams per denier and a modulus of at least about 40 grams per denier. The resin in the resin layer has a modulus of at least about 7000 psi.

  • Penetration resistant fabric
    Publication number: 20030109188
    Abstract: A laminated fabric for penetration resistant e.g. ballistic applications. The fabric comprising a fabric of penetration resistant yarns having a linear density in the range from 100 to 700 dtex, said yarns being woven in a satin weave. The woven fabric is coated on at least one-side with a polymeric material in a micro-lamination process, the coating material being from 0.
