specific Embodiment approach 1
[0016] Specific implementation mode one: as figure 1 As shown, what is described in this embodiment is a multi-layer heat-resistant and ablation-resistant composite material. The composite material is composed of an inner layer bearing layer and an outer layer heat insulation layer; An amine resin composite material layer, the outer heat insulating layer is a glass fiber reinforced methylphenyl silicone resin composite material layer; the inner bearing layer and the outer heat insulating layer are bonded by an interlayer adhesive; a The first layer is the outer heat insulation layer, that is, the glass fiber reinforced methylphenyl silicone resin composite material layer, the b layer is the inner layer bearing layer, that is, the carbon fiber reinforced polyimide resin composite material layer, and the c layer is the interlayer adhesive .
specific Embodiment approach 2
[0017] Specific embodiment two: a kind of multi-layer heat-resistant ablation-resistant composite material described in specific embodiment one, the described interlayer adhesive is silicone resin adhesive or epoxy modified silicone resin adhesive One or a mixture of both.
specific Embodiment approach 3
[0018] Embodiment 3: A method for preparing a multi-layer heat-resistant and ablation-resistant composite material described in Embodiment 1 or 2. The specific steps of the method are as follows:
[0019] Step 1: Arrange the glass fiber in an oven, keep it at 200°C-250°C for 4-6h, cool down to room temperature naturally, and then impregnate the glass fiber cloth into methyl phenyl silicone resin with a solid content of 50%. After impregnating the glass fiber cloth, dry it naturally for 24 hours by dry method to prepare a prepreg, and then put it into a mold for compression molding. 2-4 h between 130°C-150°C, 2-4 h between 130°C-150°C, 2-4h between 160°C-180°C, 4-6h between 190°C-230°C, to obtain glass fiber reinforced methyl phenyl silicone resin Composite layer;
[0020] Step 2: The glass fiber reinforced methylphenyl silicone resin composite material layer and the carbon fiber reinforced polyimide resin composite material layer obtained in step 1 are bonded together with an...
