Abstract

The invention discloses a silicon carbide lightning protection material and a preparation method thereof, and belongs to the technical field of lightning protection material preparation. The technical problem to be solved by the invention is to improve the heat-conducting property. The preparation method comprises the following steps: respectively weighing 5-25 parts by weight of silicon carbide and 75-95 parts by weight of epoxy resin, adding the weighed silicon carbide into the weighed epoxy resin under the condition of mechanical stirring, conducting stirring at normal temperature for 10-12 hours to obtain a silicon carbide epoxy resin solution, immersing carbon fibers into the epoxy resin solution to obtain a carbon fiber reinforced resin prepreg, then laying the carbon fiber reinforced resin prepreg into a carbon fiber reinforced resin prepreg plate by adopting a hand lay-up method, immersing a metal extension net into the silicon carbide epoxy resin solution, taking out the metal extension net, laying the metal extension net on the carbon fiber reinforced resin prepreg plate prepared in the step 2, carrying out vacuum hot pressing, and then conducting cooling to room temperature to obtain the silicon carbide lightning protection material. The invention is used in the field of lightning protection materials.

Description

technical field [0001] The invention belongs to the technical field of preparation of lightning protection materials; in particular, it relates to a silicon carbide lightning protection material and a preparation method thereof. Background technique [0002] At present, the main lightning protection methods include spraying metal, pasting metal foil and metal mesh, etc. These methods can only reduce the damage of lightning energy to aircraft and other structures to a certain extent, but because lightning energy will instantly generate high temperatures above 3000 °C, Instantaneous sublimation of the metal protective layer results in failure of the protective function and severe thermal damage to the carbon fiber reinforced epoxy resin-based composite material, which cannot meet the demand for non-damage protection in the field of lightning protection. [0003] Silicon carbide has attracted widespread attention due to its high thermal conductivity, high temperature resistance...
