A heated composite structure and a method for forming a heated composite structure. The structure includes carbon fibers embedded within a thermoplastic matrix. The carbon fibers are connected with first and second electrodes that are configured to be connected with an electric source such that applying current to the electrodes causes current to flow through the embedded carbon fibers to provide resistive heating sufficient to heat the composite structure to impede formation of ice on the composite structure.

A method of manufacturing an acoustic treatment panel including at least one cellular structure with at least one anchor layer at the level of at least one of its faces. The anchor layer includes at least one adhesive sheet chosen from an adhesive film or a ply of pre-impregnated adhesive fibers in contact with the cellular structure. The method of manufacture includes, before the integration of the cellular structure in an acoustic treatment panel, a step of placing the anchor layer on a support, the adhesive sheet being the last to be placed, a step of placing the cellular structure on the anchor layer in contact against the adhesive sheet, and then a step of polymerization of the anchor layer and of the cellular structure.

A method of monitoring a curing process for fiber reinforced composite materials that includes positioning an actuator on uncured composite material at a first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. The waves propagate through the composite part due to internal reflection. At least one wave metric is measured at the second location utilizing the sensor. At least one parameter of the curing process may be adjusted based, at least in part, on a wave metric measured by the sensor.

A method of placing a fastener plate on a structure made of composite material, the structure being obtained by a technique of injecting resin under a vacuum, the technique including placing a fiber preform in a closed mold, injecting a thermosetting resin into the mold, and polymerizing the resin prior to cooling. The method includes mounting a metal fastener plate against a wall of the mold before putting the fiber preform into place, the fastener plate coming into contact with one of faces of the fiber preform while the fiber preform is being put into place in the mold, and the resin becoming deposited between the fastener plate and the fiber preform while the resin is being injected into the mold. The method may be used in particular for fastening equipment on a composite material fan casing of a gas turbine for an aeroengine.

Systems and methods for curing complex fiber-reinforced composite structures utilize two distinct heat sources. A first heat source is utilized for heating a complex fiber-reinforced composite structure from within an internal portion of the complex fiber-reinforced composite structure. A second heat source is utilized for heating the complex fiber-reinforced composite structure from an external surface of the complex fiber-reinforced composite structure.

A rigid coupler for use in electrically isolating an electrically conductive fluid conveyance system is described. The rigid coupler includes a nonconductive liner having a first end configured to couple to a first adjoining section of the fluid conveyance system, and a second end, opposite said first end, configured to couple to a second adjoining section of the fluid conveyance system.
