Embodiment 1

[0082] The continuous SiC fiber was placed in a muffle furnace at 400°C for 30 minutes under air condition; that is, the pretreated SiC fiber bundle after degumming was obtained.

[0083] The SiC fiber bundle is released from the wire-feeding device and steered by the steering wheel between the electron emission gun and the magnetic induction coil. The steered SiC fiber bundle and the electron beam emitted by the electron emission gun form an angle of α, and the 0 °≤α≤5°, after the SiC fiber bundle enters the magnetic induction coil, the electron beam emitted by the electron gun makes the SiC fiber polarized with negative static electricity. The static electrostatic constriction ring O enters the magnetron sputtering device. Since the SiC fiber bundle is subjected to the Lorentz force and electrostatic repulsion in the magnetic induction coil and the electrostatic constricting ring, the fiber bundle will not be excessively dispersed, which not only enables the fiber to advance...

Abstract

The invention discloses fiber surface interface layer deposition equipment and method. The equipment comprises a filament release device, an electrostatic filament scattering device, a magnetron sputtering device, a solid adhesive device and a filament collecting device. The filament collecting device and the filament release device are positioned on two sides of the magnetron sputtering device, the electrostatic filament scattering device is positioned between the filament release device and the magnetron sputtering device, and the solid adhesive device is positioned between the filament collecting device and the magnetron sputtering device. When the equipment is in operation, fiber bundles are released from the filament release device, then move to the electrostatic filament scattering device to be scattered, enter the magnetron sputtering device in a scattered state and are bundled by the solid adhesive device after an interface layer is obtained through magnetron sputtering deposition, and the fiber bundles are finally collected by the filament collecting device. The SiC fiber surface interface layer obtained according to the preparation method is uniform in thickness distribution, controllable in thickness and low in fiber damage and is a quasi-graphene structure weak interface layer, and mechanical performances of composite materials can be remarkably improved.
