Title:
RESIN-BASED CARBON FIBER COMPOSITE PERMANENT MAGNET CONDUCTIVE CONTACT AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/139529
Kind Code:
A1
Abstract:
Disclosed are a resin-based carbon fiber composite permanent magnet conductive contact and a fabrication method therefor. The composite permanent magnet conductive contact is composed of three parts: a sleeve, a conductive core and a coil. A magnetic core in the conductive core is a cylindrical rubidium-iron-boron permanent magnet core, a composite conductor in the conductive core is an aniline-modified carbon fiber aluminum core composite wire, and the magnetic core and conductor are cured to form the conductive core by means of using epoxy resin, a secondary medium-temperature epoxy resin curing agent, and a starch-grafted sodium acrylate mechanically blended vulcanized rubber as packaging; and the coil is the aniline-modified carbon fiber aluminum core composite wire wound on the inner surface of the sleeve. The contact provided in the present invention is inherently soft, lightweight, fatigue-resistant, impact-resistant, corrosion-resistant, and has good lamination.
