[0038] refer to figure 1 , a method for preparing a controllable orthogonal arrangement Si-CF reinforced HA composite material comprises the following steps:
[0039] Step 1, pre-treatment of carbon fiber; firstly, at room temperature, clean CF with pure water, absolute ethanol, acetone and distilled water in sequence, and then put it into the carbon fiber by H 2 SO 4 solution, HCl solution, HNO 3 The solution is modified in the mixed acid solution, and finally washed with NaOH alkali solution and distilled water respectively, and bagged after drying to obtain the surface-modified CF;
[0040] Step 2, start the magnetron sputtering vacuum system. Start the mechanical pump first, and then start the molecular pump when the vacuum degree reaches below 10Pa, and continue to vacuumize under the joint action of the mechanical pump and the turbo molecular pump until the vacuum degree of the cavity reaches a certain condition. Continue to feed argon and continue vacuuming to 4×10 ...

[0059] A method for preparing a controllable orthogonal arrangement Si-CF reinforced HA composite material comprises the following steps:
[0060] Step 1, pre-treatment of carbon fiber: First, immerse CF in pure water, absolute ethanol, acetone and distilled water for 30 minutes at room temperature and ultrasonically clean it for 30 minutes. The ultrasonic frequency is 60.0KHz and the power is 80.0W. After taking it out, it was completely immersed in HNO with a mass fraction of 20%. 3 , HCl and H 2 SO 4 In the mixed acid composed of a ratio of 1:1:1, after ultrasonic treatment at room temperature for 2 hours, it was taken out and washed with distilled water, and the ultrasonic frequency and power were still 60.0KHz and 80.0W. After taking it out, it was completely submerged in 3mol / L sodium hydroxide solution, washed with distilled water, and dried at 60°C for 2 hours.
