The present invention relates to a sealing element and/or a support ring, in particular for a reciprocating compressor, manufactured by compression molding of a mixture of chips of carbon fiber-reinforced composite material, wherein at least part of the chips contains carbon fibers having a length of 3 to 20 mm, and wherein the carbon fibers in the sealing element and/or support ring have a random fiber orientation.

The present invention relates to a sealing element and/or a support ring, in particular for a reciprocating compressor, manufactured by compression molding of a mixture of chips of carbon fiber-reinforced composite material, wherein at least part of the chips contains carbon fibers having a length of 3 to 20 mm, and wherein the carbon fibers in the sealing element and/or support ring have a random fiber orientation.

The present application discloses an insulated wire and a preparation method thereof, a coil and an electronic/electrical device. According to the insulated wire, a bonding layer containing PEEK nano-powder is arranged between a conductor and a PEEK resin insulating layer, and a bonding agent for forming the bonding layer contains organic solvent, polyamide-imide resin and PEEK nano-powder material which are mixed. The bonding layer can be well bonded with both the conductor material and the PEEK resin insulating layer, so that the produced insulated wire rod has good adhesion, and cracking and detachment will not appear during application.
