STIFFENED PART FORMED FROM A THERMOSET COMPOSITE MATERIAL WITH A BOXED STRUCTURE AND MANUFACTURING METHOD
A stiffened part formed from at least two members of thermoset composite material including at least one body of a first structure and optionally a second structure. A manufacturing method includes: forming a fibre preform and impregnating each body of the first structure with thermosetting resin or forming a pre-impregnated fibre preform to obtain a body formed from uncured thermosetting composite material supported by a mandrel; optionally partially or fully polymerising at least one body supported by a mandrel; optionally, providing the second structure formed from uncured, partially uncured or fully uncured thermosetting composite material; optionally, depositing a layer of uncured thermosetting adhesive on an area where a fully cured member makes contact with another member of the part; joining the members, each member being juxtaposed with; or stacked upon, at least one other member; fully curing the assembly by heat treatment; removing the mandrel from each fully cured body.
IMPROVED STIFFENING STRUCTURE INTENDED TO STIFFEN A COMPONENT MADE OF THERMOSETTING COMPOSITE MATERIAL, AND ASSOCIATED STIFFENING METHOD
Structure intended to stiffen a component made of thermosetting composite material by being fitted to at least one of its surfaces, including: at least one longitudinal body, with first and second longitudinal edge faces on opposite sides, and first and second lateral faces on opposite sides; at least one base including at least one mounting base, each base having a plate and first and second tongues which delimit, with the plate, a housing for at least one body, the first and second tongues extending from a main face of the plate and being pressed respectively against the first and second lateral faces of the body. Each mounting base has a plate which is secured to the first longitudinal edge face of a body and which is intended to be pressed against the surface of the component to be stiffened. Each body and each base are made of thermosetting composite material.
Injection molded dielectric antenna formed with an antenna mold that compensates the dielectric during curing
In accordance with one or more embodiments, a method includes injection molding of a dielectric material in a pre-distorted antenna mold; and curing the dielectric material. The pre-distorted dielectric mold has a shape that compensates for shape distortion of the dielectric material during the curing.
BODYWORK PART WITH INTEGRATED ANTI-PINCHING SYSTEM
A bodywork part for a motor vehicle is provided. The bodywork part includes a main body made from a plastic material and an anti-pinching system. The latter comprises a capacitive sensor comprising at least a first conductive wire integrated into the thickness of the main body by welding, said capacitive sensor being able to detect the presence of an object or a hand of a user in said peripheral zone.
Injection molding electroplating for three-dimensional antennas
An antenna fabrication method includes depositing a conductive material on a surface of a double injection mold that includes a first surface portion comprising a primary material corresponding to a slot of the antenna and a second surface portion comprising an overmold material corresponding to a conductive surface of the antenna such that conductive material does not deposit on the primary material while it deposits on the secondary material, thereby resulting in multiple loops of the conductive material on the surface of the double injection mold, and providing two contact points to the conductive material, the contact points being separated from each other by a gap in the conductive material.
Over-molded thin film antenna device
An over-molded thin film antenna device is provided that can include a core mandrel having a body and a lip, a thin film radio frequency (RF) element wrapped around and supported by the body, an RF connector electrically coupled to the thin film RF element, and an outer layer molded between shutoff surfaces of the core mandrel and over the thin film RF element. The lip can extend over a top of a portion of the thin film RF element to secure the portion of the thin film radio frequency element between the body and the lip.
LOW-PROFILE WIDEBAND ANTENNA ARRAY CONFIGURED TO UTILIZE EFFICIENT MANUFACTURING PROCESSES
A low profile phased array antenna that is configured to be manufactured using additive manufacturing techniques is provided. In one or more embodiments, the phased array can include a plurality of signal ears, ground ears, and clustered pillars that can be arranged in relation to a base plate such that each component of the antenna can be manufactured from a single piece of material, thereby allowing for the use of additive manufacturing techniques which can substantially reduce the cost and time of the manufacturing process. The phased array can include a signal ear that include one or more posts that interface with an airgap located within a base plate of the array, wherein the size of the airgap in relation to the size of the post is configured to achieve an optimal level of impedance matching.
ELASTOMERIC SENSOR COMPONENT WITH AN INTEGRATED SENSOR MODULE
An elastomeric sensor component includes a component body made of elastomer material and a sensor module embedded within the component body. The sensor module includes a sensor chip, a radiofrequency transponder chip electrically connected to the sensor chip, and a loop antenna electrically connected to the radiofrequency transponder chip. The elastomeric sensor component further includes a booster antenna having a booster antenna loop, with the booster antenna loop deposited on a surface of the component body in order to allow near field data communication and energy transfer with the loop antenna.
Broadband radome structure
A radome structure for a multilayered broadband radome structure is described. The radome structure may include a central core layer comprising a first dielectric constant, an interior intermediate core layer adjacent to an interior side of the central core layer, comprising a second dielectric constant less than the first dielectric constant, an exterior intermediate core layer adjacent to an exterior side of the central core layer, comprising a third dielectric constant less than the first dielectric constant, and an interior outside core layer adjacent to an interior side of the interior intermediate core layer, comprising a fourth dielectric constant less than the second dielectric constant. In some examples of the radome structure described above may further include an exterior outside core layer adjacent to an exterior side of the exterior intermediate core layer, comprising a low dielectric constant.
A PANEL PROFILE AND METHOD FOR MANUFACTURING THEREOF
The present disclosure describes a pultruded panel profile with a sandwich structure and a method of manufacturing such a panel profile. The sandwich structure has at least one a core layer and surface layers on both sides of the sandwich structure. The core layer comprises at least one signal window section made of a signal-transparent material, the signal-transparent material being substantially transparent to at least one wireless signal. The core layer further comprises a peripheral section surrounding the signal window section, the peripheral section having a different material composition than the signal window section.
