Embodiment 1

[0030] In this embodiment, a process for making an automobile engine cover from a carbon fiber-reinforced resin-based composite material comprises the following steps, and its process structure is as follows: figure 1 Shown:

[0031] 1. Mold cleaning and preparation: the surface size of the mold 4 is 160×110 square centimeters, the surface of the mold 4 is polished smooth with 1000 mesh sandpaper, and then the surface of the mold 4 is wiped clean with alcohol;

[0032] 2. Apply the sealing agent: After the alcohol on the surface of the mold 4 is completely volatilized, apply the sealing agent 11 evenly on the surface of the mold 4, then let it stand for 30 minutes, and repeat this operation once;

[0033] 3. Paste the sealing tape: paste the sealing tape 9 around the surface of the mold 4 and 15 cm away from the edge of the workpiece;

[0034] 4. Apply release agent: evenly apply release agent 10 on the surface of the mold 4 and inside the sealing tape 9, then let it stand fo...

Embodiment 2

[0042] In this embodiment, a process for making an automobile engine cover from a carbon fiber-reinforced resin-based composite material comprises the following steps, and its process structure is as follows: figure 1 Shown:

[0043] Steps 1, 2, 3, and 4 are identical to steps 1, 2, 3, and 4 in Example 1;

[0044] 5. Cutting reinforcing material: Cut Toray T700-12K carbon fiber fabric 1 according to the size of mold 4. The carbon fiber fabric 1 is carbon fiber twill fabric and four-axis warp knitted fabric with a size of 150×100 square centimeters. Cut 2 pieces each. The cut carbon fiber twill fabric 1 is dried in an oven at 100°C for 30 minutes; a foam core material 2 similar in shape to the mold 4 is cut out, the foam core material 2 is PVC foam, and the surface size is 140 × 90 square centimeters. The edge of the foam core material 2 is cut into a tapered shape, and the tapered angle is 45°;

[0045] 6. Lay reinforcement material: pave reinforcement material on the surface ...

Abstract

The invention discloses a technology of making automobile engine cover with carbon fiber reinforcement resin-based composite material, sequentially comprising: cleaning and preparing dies, coating sealant, gluing seal tape, coating mold lubricant, cutting carbon fabric and foam core material, paving and covering carbon fabric and foam core material, paving and covering auxiliary materials, sealing the vacuum section sealed by seal tape, absorbing and injecting resin, and solidifying, demolding and trimming. The making technology of the invention requires relatively short processing period and low labor cost, and is beneficial to both environmental protection and human health. Compared with conventional metal automobile engine covers, the automobile engine cover made of carbon fiber reinforcement resin-based composite material, with equal rigidity, is light in weight, stable in quality, and satisfactory in surface effects.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile engine cover, in particular to a process for manufacturing an automobile engine cover from a carbon fiber reinforced resin-based composite material. Background technique [0002] The rapid development of the automobile industry has led to a sharp increase in car ownership, and it has also brought three major problems to the society: energy shortage, environmental pollution, and safety issues. Automobile energy saving, environmental protection and safety are not only the development direction of international automobile technology, but also the requirements of my country's automobile industry policy. Reducing fuel consumption and reducing environmental pollution has become a key issue that needs to be solved urgently for the development of the automobile industry and the sustainable development of society. [0003] The light weight of automobiles is one of the most effective ways to save...
