Embodiment 1
[0045] see figure 1 and Figure 6 Shown:
[0046] In this embodiment, a directional distributed chopped carbon fiber reinforced hydroxyapatite-based composite material is prepared, including the following steps:
[0047] Step 1: Select the composition and mass percentage of raw materials
[0048] Chopped carbon fiber 0.5%: chopped carbon fiber average diameter 7μm, length 2-3mm;
[0049] Dispersant system 2%: the amount of surfactant 1%; the amount of dispersant 1%, the dispersant is composed of polyethylene oxide (PEO) and polyacrylamide (PAM) with a mass ratio of 3:1;
[0050] Matrix material 97.5%: hydroxyapatite powder;
[0051] Step 2: Pre-dispersion of Chopped Carbon Fiber
[0052] Take a beaker, pour the weighed chopped carbon fiber, surfactant, and dispersant into the beaker, then add a certain amount of deionized water, and stir with a glass rod to disperse the chopped carbon fiber evenly; then extend the ultrasonic probe into In the liquid, with a power of 800W...
Embodiment 2
[0061] The steps of this embodiment and embodiment 1 are the same, and the difference is that the components of the raw materials in step 1 are different. In the present embodiment, the mass percentages of the raw materials are as follows:
[0062] Chopped carbon fiber 0.3%: chopped carbon fiber average diameter 7μm, length 2-3mm;
[0063] Dispersant system 2%: the amount of surfactant is 0.4%; the amount of dispersant is 1.6%, and the dispersant is composed of polyethylene oxide (PEO) and polyacrylamide (PAM) with a mass ratio of 3:1;
[0064] The balance is matrix material.
Embodiment 3
[0066] The steps of this embodiment and embodiment 1 are the same, and the difference is that the components of the raw materials in step 1 are different. In the present embodiment, the mass percentages of the raw materials are as follows:
[0067] Chopped carbon fiber 0.8%: chopped carbon fiber average diameter 7μm, length 2-3mm;
[0068] Dispersant system 1%: the amount of surfactant is 0.2%; the amount of dispersant is 0.8%, and the dispersant is composed of polyethylene oxide (PEO) and polyacrylamide (PAM) with a mass ratio of 3:1;
[0069] The balance is matrix material.
