An article comprises a multi-directional textile of first reinforcing fiber tows extending in a first direction and second reinforcing fiber tows extending in a second direction. Filaments in the first fiber tows extend past a boundary of the textile and are spread. The tows are embedded in resin.
摘要:
The present invention sufficiently heats a repairing material while preventing change in quality of a base material provided with the repairing material so as to securely bond the repairing material to a repair target portion. The repair method of the present invention, in order to repair a repair target portion 14 existing in an outer panel 1, includes: a repairing material disposing step of disposing a repairing patch 21 including a resistance heating element 23 and a carbon fiber reinforced resin, and an adhesive 22A including a thermosetting resin before being hardened for bonding the repairing patch 21 on the repair target portion 14; and a heating-hardening step of heating and hardening the thermosetting resin of the adhesive 22A by causing the resistance heating element 23 to generate heat through supply of electricity thereto.

A restructured, recycled or repurposed slab such as stone, wood or the like which includes a primary component and a secondary component which fills a fissure, crack or break in the slab. The secondary component being configured to restore the structural integrity and/or providing a continuous surface. The secondary component configured to provide a noticeable contrast in appearance to the primary component.

A method for modifying a ceramic matrix component is disclosed including identifying a non-conforming region of a composite component capable of operating in a gas turbine engine; removing at least a portion of the non-conforming region to create an exposed surface of the composite component; preparing a preform in response to the removing at least a portion of the non-conforming region; applying a reactive constituent surface region to at least one of the exposed surface of the composite component and the preform, the reactive constituent surface region being capable of producing a non-equilibrium condition; positioning the preform to provide a contact region between the exposed surface of the composite component and the preform proximate the reactive constituent surface region; and reacting the reactive constituent surface region in an equilibrium reaction at the contact region to form a bond structure between the exposed surface of the composite component and the preform.
摘要:
A patch for reworking an inconsistent area in a composite structure includes a composite laminate patch adapted to cover the inconsistent area and bonded to the structure by a layer of adhesive. The patch includes a plurality of composite plies having a tapered cross section, and at least first and second regions respectively having differing fracture toughnesses.

This invention is a method and apparatus for repairing a hole in a surface with a perforated repair patch. The repair patch, which is affixed to and substantially cover over the hole, is indented inwards by applying cement compound into its perforations and pushing the repair patch into the hole as the cement compound hardens. A layer of drywall compound is then applied over the indented repair patch to smooth it with the rest of the wall. The perforated repair patch may include an additional layer of mesh sheet material to minimize cracking of the drywall compound.
摘要:
A drywall patch is coated with a premeasured amount of joint compound in its wet state making it immediately available for application to a wall surface. The patch with compound is sealed in an airtight wrapper or between unsealed wrapper halves which are in turn sealed in a surrounding airtight package so that the joint compound stays moist and will not harden over time. The wrapper includes a peel-away adhesive dry patch. In use, the dry patch is first applied over a crack or hole to be repaired. The wrapper and compound are applied directly over the dry patch and, while the wrapper remains in place, pressure is applied to smooth the compound over the patch and removed after the compound has dried. The wrapper is preferably composed of microporous breathable plastic film.

A technology for remedying a defect in a glass substrate which constitutes a display panel. There is provided a method of remedying a defect in a glass substrate which constitutes a display panel, which method includes performing grinding of glass material, until reaching internal bubble (1b) from surface (1s) of glass substrate (1), with respect to a region where the internal bubble (1b) occurring within the glass substrate (1) is positioned and further also grinding off a glass material position surrounding the internal bubble (1b).

The invention aims to enable rapid and efficient repair of damaged metal structures, in particular airframe fuselage skins, without necessitating any additional thickness compromising the transmission of waves. To this end it proposes a double internal/external plate constituted by a particular material. In one embodiment, the damaged structure having an external face and an internal face, the part features a substantially plane double internal/external plate adapted to be fastened to the internal face and the external face of the metal structure, respectively, and a central hub connecting the internal plate and the external plate. A groove is thus formed between these plates. The part is constituted of a single composite material block, and a glass ply, lining the groove, may be positioned between the plates and the structure. The hub may have passing through it at least one orifice adapted to allow connections to pass through the structure.
