Abstract: In an embodiment, a material includes at least one outer section and a midsection attached to the outer section. The midsection includes a first antimicrobial membrane patch layer configured to contact a body, a second antimicrobial membrane patch layer disposed adjacent to the first antimicrobial patch layer, and an air gap disposed between the first patch and second antimicrobial patch layers. The first and second antimicrobial patch layers each are formed from respective balanced warp tows and fill tows in a plain-weave pattern, and each layer include copper filaments disposed in a plurality of the tows, each of the copper filaments including at least Cu+ or Cu+++ ions. Such a material may be suitable for notification and protection of a body from a soil deposited on the material.

Abstract: A process for preventing multiplication of a bacteria, virus, or fungus, via: embedding Cu+ and Cu+++ ions into a material; contacting the bacteria, virus, or fungus with the material; and diffusing the Cu+ and Cu+++ ions into a cell and thereby reducing a biological energy-producing ability of the cell, via creating an inhibitory protein molecular structure degrading a membrane anatomy of the cell, thus suffocating the cell, thus protecting a skin from infection and preventing multiplication of the bacteria, virus, or fungus. Also described is a process for sensing: a load, a strain, or a liquid, on a fabric, that includes forming the fabric comprising a multi-walled nanomaterial tube copper bio-sensor via: spacing apart from one another, rows of multi-walled nanofibers, the rows of multi-wall nanofibers comprising copper; and spacing a continuous filament apart from and disposed substantially perpendicular to the rows of multi-walled nanofibers.

Abstract: In an embodiment, a garment, such as a smart pull-up, includes at least one outer section and a midsection attached to the outer section. The midsection includes a first antimicrobial membrane patch layer configured to contact a wearer's body, a second antimicrobial membrane patch layer disposed adjacent to the first antimicrobial patch layer, and an air gap disposed between the first patch and second antimicrobial patch layers. The first and second antimicrobial patch layers each are formed from respective balanced warp big tows and fill tows in a plain-weave pattern, and each layer include copper filaments disposed in a plurality of the tows, each of the copper filaments including at least Cu+/Cu+++ ions. Such a smart pull-up may be suitable for either adult who cannot use the toilet, or child, or healthy adult and, therefore, may urinate and defecate himself/herself.

Abstract: A patch for a structure has a rework area with an inconsistency formed therein. The patch comprises a patch body having at least two regions including a fail-safe region and a safe-life region encompassing the fail-safe region. The safe-life region has a mode I interlaminar fracture toughness that is less than the mode I interlaminar fracture toughness of the fail-safe region.

Abstract: A system for repair of damaged holes in composite structures incorporates a repair system tool device having a sleeve sized to be closely received in a hole in a composite structure. The sleeve has a central bore for receiving parent resin and an array of orifices for radial expulsion of the parent resin into the hole. A caul plate seals the central bore and a vacuum bag covering the caul plate is sealed to the surface of the composite structure. Introduction of vacuum in the vacuum bag provides a differential pressure for infusion of resin from the orifices in the sleeve into delaminations extending from the hole.

Abstract: A unitized composite aircraft wing includes upper and lower composite laminate wing skins that have differing stiffnesses and are bonded to a composite grid structure. The grid structure includes grid spars extending in a span-wise direction, and cross beams extending in a chord-wise direction of the wing. The grid spars include caps bonded to the upper and lower wing skins.

Abstract: A bond surface testing apparatus includes a solution chamber; a plurality of solutions in the solution chamber, the solution chamber adapted to dispense the solutions onto a bonding surface; an information capture module carried by the solution chamber and adapted to capture information relating to bonding surface properties of the bonding surface; at least one analysis module interfacing with the information capture module and adapted to analyze the bonding surface properties of the bonding surface; and a structural wettability factor prediction module interfacing with the at least one analysis module and adapted to predict a structural wettability factor based on the bonding surface properties.

Abstract: The condition of a bond surface is determined. A 3-D wettability tension curve is generated for the bond surface which represents a range of possible wettings of an adhesive on the bond surface that may result in a bond joint of acceptable quality. At least three surface energies on the bond surface are measured, and the wettability curve is used to determine whether the condition of the bond surface is acceptable based on the measured bonding surface energies.
