When the nonwoven fabric substrate (1) is seen in planar view, the nonwoven fabric substrate (1) has an aperture region (11) formed by the aperture portion (3h) of the plurality of grooves (3), and a non-aperture region (12) formed by the non-aperture portion (3n), and the aperture region (11) and the non-aperture region (12) are arranged in a predetermined pattern.

A baffle or reinforcer includes a carrier configured to be disposed in a cavity and a fixation mechanism disposed on the carrier and configured to at least partially support the carrier in the cavity. The fixation mechanism defines an opening for receiving an expandable material. The fixation mechanism has an anti-return device configured to prevent at least a portion of the expandable material from escaping through the opening during expansion. A method includes inserting the carrier into the cavity, injecting the expandable material into the cavity via the opening in the fixation mechanism, expanding the expandable material within the cavity, and preventing at least a portion of the expandable material from escaping through the opening during expansion.

A method for modifying an aperture in a component, a system for modifying flow through a component, and a turbine component are disclosed. The method includes providing a substrate having at least one aperture having an electrically-conductive surface, providing a deposition device including an ESD torch, the ESD torch including an aperture penetrating electrode including a conductive material, inserting the aperture penetrating electrode at least partially into the aperture, and generating an arc between the aperture penetrating electrode and the electrically-conductive surface to deposit electrode material within the aperture. The system includes the ESD torch removably supported in an electrode holder. The turbine component includes at least one aperture having an electrospark deposited material along an electrically-conductive surface, the electrospark deposited material providing modified fluid flow through the turbine component.

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.

The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure and a protective cover element constructed and arranged to fit various structures, such as boat propellers.

Aspects herein relate to apparel items and apparel systems that utilize applied or printed foam nodes to provide, among other things, stand-off between an apparel item and a wearer's skin surface. One or more of the foam nodes, or areas of the textile surrounding the foam nodes, may be perforated to provide a fluid communication path between an inner-facing surface and an outer-facing surface of the apparel item. The communication path may be used to facilitate air exchange between the external environment and the wearer's body and/or to provide an exit path for moisture vapor generated by the wearer.
