Sheet comprising a flexible support and a coating at least partially covering at least one face of the support, the support being made of a support material exhibiting dielectric properties, the coating being made of a coating material different from the support material and exhibiting magneto-dielectric properties or dielectric properties.

A composite sandwich panel includes a first composite part and a second composite part. A plurality of stiffeners extend between the first and second composite parts. A fiberglass composite perimeter edge closeout is positioned along one or more edges of the first and second composite parts. The fiberglass composite perimeter edge closeout controls a magnetic flux to bond the first and second composite parts to the plurality of stiffeners.

The present invention relates to a thermoplastic laminate for an eyewear, a decorative part comprising the thermoplastic laminate and a preparation process therefor. In particular, during the preparation of the laminate, a high frequency welding machine is used for bonding thermoplastic layers. The present invention uses a high frequency welding machine for the instant welding of the thermoplastic layers. Good bonding strength exists between different layers. Further, the patterns of the core layer are intact, and have high-definition images. The patterns are located in the core layer, not affected by external environmental factors, and not easily abraded. Further, multiple surfaces of the part for an eyewear have patterns, increasing the beautiful appearance of the part for an eyewear, and meeting the requirements of customers to the largest extent.

A black sealant composition includes magnetic nanoparticles including a core and a shell surrounding the core, conductive black particles having a black color, and a resin including the magnetic nanoparticles and the conductive black particles dispersed therein.
