The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

COMPOSITE MATERIAL AND METHOD OF FORMING COMPOSITE MATERIAL

The purpose of the present invention is to provide: a composite material which when bent and formed, can prevent the occurrence of problems such as the occurrence of wrinkles of the composite material, an increase in the number of forming steps, and difficulty in forming the composite material; and a method of forming the composite material. This composite material (1) comprises a laminate (2) in which a plurality of fiber sheets are laminated, wherein the laminate (2) has a to-be-bent portion (3) that is to be bent along a mold, and in a region (5) of the laminate (2) from an end edge (4) on a bent side to the to-be-bent portion (3), the laminate (2) is divided into a plurality of layers along the plate thickness direction of the laminate (2).

The article of headwear having at least one fabric panel with a non-embroidered, ornamental image. At least a portion of the fabric panel with the ornamental image is embossed in relief, to define an embossed portion of the fabric panel with the first surface of the embossed portion of the fabric panel having a raised profile and contour above a remaining portion of the first surface of the fabric panel, to define a three-dimensional effect to at least a portion of the ornamental image on the fabric panel.

Method of manufacture for thin, multi-bend optics by vacuum molding

A method includes placing an optical substrate onto a vacuum mold having a bent contact surface characterized by a surface roughness. The method further includes bending, by an applied bending force, the optical substrate and the protective sheet to cause the protective sheet to come into contact with the bent contact surface of the vacuum mold, generating a vacuum-induced holding force to hold the protective sheet against the bent contact surface of the vacuum mold. After a holding time period, the vacuum-induced holding force is released. During molding, a protective sheet provides a buffer layer between the bent contact surface of the vacuum mold and an optical surface of the optical substrate thereby mitigating against transfer of the surface roughness of the bent contact surface onto the optical surface.

Apparatus and methods of forming selected portions of integral sheets of material are disclosed. Unformed portions of the sheets may remain undistorted during the forming process, allowing them to contain text, art work, or other desired information without material risk of the information being degraded or becoming unintelligible during the forming process. This result may be accomplished, moreover, with less trim than usually occurs in conventional forming processes.

COMPONENT SHIELDING

A method of manufacturing a component for a gas turbine engine includes applying a thermoplastic polymer sheet over a composite body for the component; applying a shield over part of the composite body, the shield terminating at an end which overlies the thermoplastic polymer sheet and defines an interface between shielded and unshielded regions of the component; and pressing the shield into the thermoplastic polymer sheet so that the thermoplastic polymer sheet deforms around the end of the shield, such that the exterior profile of the component at the interface between the shielded and unshielded regions is flush.

System for producing a fully impregnated thermoplastic prepreg

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

Apparatus for forming a contoured hat stiffener

A flexible punch and die are used to form a flat composite laminate charge into a stiffener having a desired cross sectional shape. A desired contour is formed in the stiffener by bending the punch and die. Ply wrinkling is avoided during contouring by maintaining those portions of the stiffener subject to wrinkling in tension as the contouring is being performed. Bridging of the plies during the contouring process is avoided by first contouring those sections of the stiffener that are subject to wrinkling, and then contouring the remaining sections of the stiffener.
