Multi-cell heating blankets that facilitate composite fabrication and repair
Systems and methods are provided for curing a composite part. The method includes the steps of: disposing a heat blanket at a composite material; applying, with a controller, power to heaters distributed across multiple cells of a heat blanket to heat the composite material at the heat blanket; monitoring, with the controller, a temperature of the composite material at each of the multiple cells via thermocouples distributed across the multiple cells; and individually adjusting, with the controller, an amount of power applied to the heaters, for each of the multiple cells, in response to the monitored temperature and a target temperature.
Methods of embedding an elongate susceptor within a thermoplastic body
Methods of embedding an elongate susceptor within a thermoplastic body and systems that perform the methods are disclosed herein. The methods include extending the elongate susceptor such that an extended portion of the elongate susceptor extends between a guide structure and a body-contacting structure. The methods also include heating a segment of the elongate susceptor to produce a heated portion of the elongate susceptor. The methods further include pressing a leading region of the heated portion of the elongate susceptor through a body surface of the thermoplastic body and into the thermoplastic body. The methods also include operatively translating at least one of the guide structure, the body-contacting structure, and an application tool that includes the guide structure and the body-contacting structure along an embedment pathway for the elongate susceptor.
METHOD FOR REPAIRING A RADOME USING THE RADOME AS A HEATING CHAMBER AND TOOL FOR IMPLEMENTING SAME
A method and tool for repairing a damaged zone of an aircraft radome, using the actual radome itself as a heating chamber to avoid resorting to an autoclave and the removal of certain parts of the radome which cannot withstand the curing temperature needed for the repair. The method for repairing a radome, wherein the radome comprises a composite panel exhibiting a double curvature forming a dome, the panel comprising at least one damaged zone, comprises the steps of closing an interior space of the panel using a cap to form a repair chamber. The surface of the panel forms the repair chamber containing the damaged zone. Another step is heating the space inside the repair chamber to form a heating chamber allowing the curing expected for repairing the damaged zone.
INSPECTION AND REPAIR OF ADHESIVE-BONDED JOINT USING ULTRASONIC PULSES
A method of inspection and repair of a joint in an assembly. The joint is formed by a first work piece and a second work piece. An adhesive placed between the first and second work pieces to define the joint. The assembly includes an ultrasonic welding device including an ultrasonic horn configured to deliver ultrasonic energy to the joint. A controller is operatively connected to the ultrasonic welding device. The controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of inspecting and repairing the adhesive-bonded joint. The controller is programmed to deliver a first ultrasonic pulse (P1) to the joint, via the ultrasonic welding device, and determine an adhesive coverage (AC) based at least partially on the first ultrasonic pulse (P1).
THREE-DIMENSIONAL SELECTIVE REPAIRING SYSTEM, APPARATUS AND APPLICATION METHOD THEREOF
A three-dimensional selective repairing system, which is for selectively repairing an area of an unrepaired element by sintering, includes a scanning device, a comparing device, a spraying device and a sintering device. The scanning device is for scanning the area to obtain a repairing data. The comparing device is connected to the scanning device to receive the repairing data and produce a repairing parameter. The spraying device is controlled by the repairing parameter and includes an electrostatic generator which sprays a plurality of electrified pulverulent bodies through the electrostatic generator to form an electrified pulverulent film on a medium covered on the area. The sintering device is controlled by the repairing parameter to provide a power beam to selectively heat the electrified pulverulent film. The electrified pulverulent film melted or sintered to form a solid mass on the area.
METHODS AND SYSTEMS FOR CURING MATERIALS WITHIN CAVITIES
Provided are methods for heat curing of various materials, such as heat curable materials or more specifically potting compounds, which are disposed within cavities with limited access to these materials. Also provided are curing for executing such methods. In some embodiments, a heat curable material disposed within a cavity may be heated by a heating rod protruding into the cavity or through the cavity. The heating rod is thermally coupled to the heat curable material and is used to transfer heat to the heat curable material. For example, the heating rod may include a resistive heating element. The heating element may be positioned in such a way that the heat curable material is selectively heated within the cavity without significant heating of surrounding components. In some embodiments, the heating rod may be also used to compress the part containing the cavity or a stack including this part.
