Resin-based carbon fiber composite permanent magnet conductive contact and manufacturing method thereof

Abstract

The invention discloses a resin-based carbon fiber composite permanent magnet conductive contact and a manufacturing method thereof. The composite permanent magnet conductive contact is composed of three parts: a sleeve, a conductive core body and a coil, wherein a magnetic core in the conductive core body is a cylindrical rubidium-iron-boron permanent magnet core; a conductor compounded in the conductive core body is an aniline modified carbon fiber aluminum core composite wire; the magnetic core and the conductor are packaged and cured into the conductive core body through epoxy resin, a sub-medium temperature epoxy resin curing agent and starch graft sodium acrylate mechanical blending vulcanized rubber; and the coil is an aniline modified carbon fiber aluminum core composite wire woundon the inner surface of the sleeve. The composite material is soft in nature, light in weight, fatigue-resistant, impact-resistant, corrosion-resistant and good in fitting.

Description

technical field [0001] The invention relates to the technical field of electrical devices, in particular to a resin-based carbon fiber composite permanent magnet conductive contact and a manufacturing method thereof. Background technique [0002] Composite electrodes for water environment are special parts used in high-temperature environments. At present, most composite electrodes in this technical field use titanium plates coated with ruthenium. The thickness of the ruthenium layer is about 100 μm. The titanium plate is used as the anode, and the ruthenium layer is used as the cathode. However, since both titanium and ruthenium are noble metals, the composite electrode is very expensive and difficult to be accepted by users, and this composite electrode is easily corroded, thus limiting its application field. Therefore, it is very important to develop a new composite electrode. In view of this situation, the resin composite electrode can better solve the shortcomings of t...

Problems solved by technology

However, the existing sensors based on polymer conductive composite materials generally have the shortcomings of obvious hysteresis, low linearity, and poor stability of the conductive network. In addition, there are also defects in the interpretation of the conductive mechanism of some composite materials during the strain process.
