Title
(EN) ADAPTION OF TEXTILE ARTICLE FOR RADIO FREQUENCY (RF) ABSORPTION AND ATTENUATION
(FR) ADAPTATION D'ARTICLE TEXTILE POUR ABSORPTION ET ATTÉNUATION DE RADIOFRÉQUENCE (RF)
Abstract
(EN)
The present disclosure describes techniques for fabricating a textile article from a laminate formed by curing a reinforced fiber matrix and a resin substrate. The resin substrate may include iron oxide particles, such as iron oxide, Fe3O4, that are capable of absorbing and attenuating RF signals within a desired RF signal range, namely 0 GHz - 3 GHz, 3 GHz, - 8 GHz, and greater than or equal to 10 GHz. The iron oxide particles may include Fe3O4Fe, Fe3O4Ni, or Fe3O4, and/or so forth. Each iron oxide particle is selected based on the RF signal range that the textile article is intended to absorb. In other words, a change in iron oxide particle composition and proportion by volume may impact the RF signals absorbed and attenuated by the textile article.

La présente invention concerne des techniques de fabrication d'un article textile à partir d'un stratifié formé par durcissement d'une matrice de fibres renforcées et d'un substrat de résine. Le substrat de résine peut comprendre des particules d'oxyde de fer, telles que de l'oxyde de fer, Fe3O4, qui sont capables d'absorber et d'atténuer des signaux RF dans une plage de signaux RF souhaitée, à savoir de 0 GHz à 3 GHz, de 3 GHz à 8 GHz, et 10 GHz ou plus. Les particules d'oxyde de fer peuvent comprendre du Fe3O4Fe, du Fe3O4Ni, ou du Fe3O4, etc. Chaque particule d'oxyde de fer est sélectionnée sur la base de la plage de signaux RF que l'article textile est destiné à absorber. En d'autres termes, une modification dans la composition et la proportion en volume des particules d'oxyde de fer peut impacter les signaux RF absorbés et atténués par l'article textile.
