Embodiment 1
[0029] See attached figure 2 As shown, the above-mentioned mold is used to prepare a ceramic matrix composite reinforced structure. The steps of forming and the method of using the mold are as follows:
[0030] Step 1. Use 45 to process the forming mold. The structure of the formed part is a flat plate reinforced structure. The angle of the matching surface of the processing rib and the slider is 25-50°. times.
[0031] Step 2: Cut and lay the SiC fiber prepreg according to the size requirements of the molding component, then place the prepreg in the compression molding mold, and install the left and right sliders and the core mold of the molding mold. Confirm the installation position of each module, and after ensuring that the installation is correct, install the mandrel bar and male mold;
[0032] Step 3. Place the mold on the press, set the temperature rise rate of the press to 2°C / min, raise the temperature to 300°C, set the pressure to 10Mpa, and keep the pressure for...
Embodiment 2
[0036] Using the above mold to prepare another ceramic matrix composite material reinforced structure, the forming steps and the method of using the mold are as follows:
[0037] Step 1. Use 3Cr2Mo to process the forming mold. The structure of the formed part is a flat plate reinforced structure. The angle of the matching surface of the processed rib and the slider is 30°~50°. 2 times.
[0038] Step 2: Cut and lay the SiC fiber prepreg according to the size requirements of the molding component, then place the prepreg in the compression molding mold, and install the left and right sliders and the core mold of the molding mold. Confirm the installation position of each module, and after ensuring that the installation is correct, install the mandrel bar and male mold;
[0039] Step 3. Place the mold on the press, set the temperature rise rate of the press to 2°C / min, raise the temperature to 350°C, set the pressure to 8Mpa, and keep the pressure for 6h;
[0040] Step 4. After ...
Embodiment 3
[0043] Using the above-mentioned mold to prepare yet another ceramic matrix composite reinforced structure, the forming steps and the method of using the mold are as follows:
[0044] Step 1. Use 3Cr2Mo to process the forming mold. The slider, female mold and male mold forming surfaces are all processed into arc shapes, which are used to prepare the reinforced structure of arc parts. The angle of the processed rib and the mating surface of the slider is 30-45° , The matching length of the male mold and the female mold slideway is 5 times the thickness of the component.
[0045] Step 2: Cut and lay the SiC fiber prepreg according to the size requirements of the molding component, then place the prepreg in the compression molding mold, and install the left and right sliders and the core mold of the molding mold. Confirm the installation position of each module, and after ensuring that the installation is correct, install the mandrel bar and male mold;
[0046] Step 3. Place the...
