Preparation method of carbon fiber reinforced pantograph slide plate with grown silicon carbide nanowires
The invention provides a preparation method of a carbon fiber reinforced pantograph slide plate with grown silicon carbide nanowires, and relates to the technical field of pantograph slide plate preparation, and the preparation method comprises the following steps: carrying out desizing treatment on pitch-based carbon fibers, and after desizing, dipping the pitch-based carbon fibers in a catalyst for pretreatment to obtain carbon fibers; growing silicon carbide nanowires on the surfaces of the carbon fibers in situ by adopting a chemical vapor deposition method; dispersing the carbon fibers on which the silicon carbide nanowires grow; mixing and kneading the carbon fibers on which the silicon carbide nanowires grow after dispersion treatment with pitch coke, petroleum coke and artificial graphite melt according to a preset volume ratio, performing sheet binding, powdering, performing hydraulic forming, and sintering and carbonizing to obtain the carbon fiber reinforced pantograph slide plate. The silicon carbide nanowire is used as an intermediate phase, so that the interface bonding force between the carbon fiber and a carbon matrix is improved, and the technical indexes such as electrical conductivity, thermal conductivity, bending strength and impact toughness of the pantograph slide plate are improved.
