A disposable surgical gown is provided. The gown includes a front panel and sleeves formed from a first spunbond layer, a nonwoven (e.g., SMS) laminate, and a liquid impervious, moisture vapor breathable elastic film disposed therebetween. The gown also includes a first and second rear panels formed from a nonwoven laminate that is air breathable and allows for an air volumetric flow rate ranging from about 20 standard cubic feet per minute (scfm) to about 80 scfm. The gown further includes a collar formed from an air breathable knit material positioned adjacent a proximal end of the gown. The collar defines a neck opening having a v-neck shape adjacent the front panel. The v-neck shape forms an angle of greater than 90° at the neck opening. The combination of features results in a reduced-glare gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.

A hole plug that can be used during rework or repair of a composite fiber assembly includes various features that allow placement of a vacuum force to the surface being reworked or repaired. In some implementations, the hole plug can include a plurality of nubs positioned around a shank. The nubs can secure the hole plug to the composite fiber assembly until a cure of an adhesive. The hole plug can further include a plurality of longitudinally oriented grooves extending along the shank and positioned between the plurality of nubs, and can include a notch positioned circumferentially around the shank. The grooves and notch can be used as adhesive carriers that assist with dispersal of a sufficient volume of the adhesive onto other portions of the shank and the composite fiber assembly during insertion of the hole plug into a hole in the composite fiber assembly.

A composite structure of a cargo body and a method of making the same are disclosed. The composite structure includes at least one electrical grid embedded within fiber-reinforced polymer (FRP) layers. The embedded electrical grid includes a plurality of conductive fibers and a plurality of insulating fibers integrated into a polymer matrix of the FRP layers. The embedded electrical grid may be used for power distribution, structural strengthening and stiffness, and/or puncture detection.

This invention relates to a wind turbine blade component, a method of manufacturing such a wind turbine blade component and a wind turbine blade comprising the wind turbine blade component. The wind turbine blade component comprising a stack of layers arranged in a first group and in a second group, wherein the layers of each group has the same width. The layers of each group is continuously offset in an edgewise direction to form a tapered edge profile. The first group of layers may be arranged relative to the second group, or in an alternating order. The layers of the first group may further have a first length which is greater than a second length of the layers of the second group.

A patient securing overlay is provided that includes a sheet of fabric for supporting a patient's torso on a surgical table. The sheet of fabric has an upper surface configured to face the patient and a lower surface configured to face a surgical table mattress or underbody support. The sheet of fabric includes friction enhancing elements applied to at least a portion of the upper surface thereof. The sheet of fabric can include an extension at a foot end of the sheet of fabric that provides material to be tucked under a foot end of the surgical table mattress or underbody support for securing the foot end of the sheet of fabric to the surgical table mattress or underbody support. The extension can include one or more friction enhancing elements.

A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

In an aspect of the invention there is provided a blast protection panel, comprising a package of fibre-reinforced resin sheets, each sheet having a dominant unidirectional fibre orientation, said package of fibre-reinforced resin sheets formed in packed stacks, each stack comprising at least four fibre-reinforced resin sheets with dominant unidirectional fibres oriented, within said each stack, alternatingly at about right angles relative to each other; and said each stack packed against adjacent stacks, said adjacent stacks comprising sheets with dominant unidirectional fibres oriented at acute angles relative said each stack thereby forming a delamination interface.

Provided are a thermosetting epoxy resin composition and a prepreg, laminated board and printed circuit board using the thermosetting epoxy resin composition. The thermosetting epoxy resin composition comprises the following components in parts by weight: 2-10 parts of a phosphorus-containing anhydride, 5-40 parts of a phosphorus-free anhydride, 5-45 parts of an epoxy resin, 40-70 parts of a filler, and 0-15 parts of a phosphorus-containing flame retardant, with the total part by weight of all these components being 100 parts, wherein the phosphorus-containing anhydride has a structure as represented by formula I or II, and the epoxy resin is selected from one of or a combination of at least two of a bisphenol A epoxy resin, a bisphenol F epoxy resin and a biphenyl epoxy resin. The thermosetting epoxy resin composition also has good heat resistance, discoloration resistance and dimensional stability after curing while ensuring V-0 grade flame resistance, and can be used for the preparation of printed circuit board substrates in the field of LEDs.

A preformed material for use in fiber-reinforced composite materials, the preformed material including one or more fiber rovings including parallel fibers wherein the fiber rovings include one or more folds in a direction parallel to the direction of the fibers and wherein the unfolded width of the fiber rovings have a width included in a range from 0.3 mm to 5 mm. The fiber density by volume may be included in a range from 10% to 75% of fibers. The thickness of a fiber roving may be included in a range from 50 .Math.m to 2 mm.
