Regardless of whether it is thermosetting or thermoplastic carbon fiber board, the nature of the composition has not changed much. The carbon fiber precursor can withstand high temperatures of thousands of degrees Celsius, while the heat resistance of the resin matrix is relatively poor, but it continues Whether heating will affect the shape and performance of the carbon fiber board depends on the heating temperature.
If the temperature exceeds the melting point of the resin, the natural carbon fiber board will soften, crack, or even decompose. Not to mention the mechanical properties, it will not even be able to maintain the shape of the board. And if the heating temperature is not high, but the continuity is longer, it may also have a certain impact on the carbon fiber board. If the time is long, it will also cause the softening problem of the carbon fiber board.
Carbon fiber board cannot withstand high temperature. This is one of its biggest flaws. Fortunately, researchers have already had some countermeasures, such as coating a layer of heat insulation on the outside of carbon fiber board, which can withstand high temperature and even open flames in a short time. Plancha. With the in-depth research on carbon fiber and other materials, high-temperature-resistant carbon fiber boards may indeed appear in the future.
