Embodiment 1
[0014] Example 1: Selecting copper oxide CuO with a particle size of 5 μm and aluminum oxide AL with a particle size of 15 μm 2 O 3 , And then add 1.5% by mass of silane coupling agent and 400% by mass of acetone respectively, and ultrasonically shake for 30 minutes, and then put them in a drying oven at 80°C. After the acetone is evaporated, take it out and grind it through a 200-mesh sieve; After the polyacrylonitrile (PAN)-based carbon fiber is oxidized in the air, the mass percentage is 20% alumina, 15% copper oxide, 8% carbon fiber and 57% nylon 1010, and then mixed in the ball mill. 8 hours, and then placed in the injection molding machine (plunger injection molding machine or screw injection molding machine), use the automatic rotating plunger for melt mixing, so that the oxide particles and fibers are fully mixed with nylon 1010 in a molten state, and heated to 200°C. After the blended composite material is completely melted, it is injected into a mold heated to 80°C with ...

[0015] Example 2: Selected copper oxide CuO with a particle size of 12μm and aluminum oxide AL with a size of 22μm 2 O 3 , And then add 2% by mass silane coupling agent and 400% by mass acetone respectively, then ultrasonically shake for 30 minutes, and then put them in a drying oven at 80°C, after the acetone is evaporated, take it out and grind it through a 200-mesh sieve; After the polyacrylonitrile (PAN)-based carbon fiber is oxidized in the air, 21% aluminum oxide, 16% copper oxide, 10% carbon fiber and 53% nylon 1010 are mixed according to the mass percentage, and then mixed in the ball mill. After 8 hours, it is placed in an injection molding machine (either plunger injection molding machine or screw injection molding machine) for melt mixing, so that oxide particles and fibers and nylon 1010 are fully mixed in a molten state, and heated to 220°C. After the blended composite material is completely melted, it is injected into a mold heated to 80°C with an injection pressure ...

[0016] Example 3: Selected copper oxide CuO with a particle size of 24 μm and aluminum oxide AL with a particle size of 30 μm 2 O 3 , And then add 2% by mass silane coupling agent and 400% by mass acetone respectively, then ultrasonically shake for 30 minutes, and then put them in a drying oven at 80°C, after the acetone is evaporated, take it out and grind it through a 200-mesh sieve; After the polyacrylonitrile (PAN)-based carbon fiber is oxidized in the air, the mass percentage is 22% alumina, 18% copper oxide, 12% carbon fiber and 48% nylon 1010, and then mix in the ball mill. After 8 hours, it is placed in an injection molding machine (either plunger injection molding machine or screw injection molding machine) for melt mixing, so that oxide particles and fibers are fully mixed with nylon 1010 in a molten state, and heated to 220°C. After the blended composite material is completely melted, it is injected into a mold heated to 80°C with an injection pressure of 65 MPa to form...
