Embodiment 1

[0018] The present invention proposes a new type of wax core molding carbon fiber molding technology, which includes the following steps:

[0019] S1: First, prepare raw materials, prepare 10 parts of ceramic fiber, and the content of alumina in this kind of ceramic fiber accounts for 60%, and 5 parts of dispersant. This kind of dispersant is an inorganic dispersant, and the inorganic dispersant can be used in the fiber Improve the gloss of the fiber and reduce the overall viscosity of the fiber during molding. 2 parts of binder, 2 parts of additives, remove the above materials, according to the ratio of ceramic fiber, dispersant, binder and additives 10:2:1:1, Mix into a slurry at a temperature of 20°C;

[0020] S2: Take an appropriate amount of the slurry in step S1, and then use a non-clogging pump to drive into the molding tank, immerse the perforated mold into the slurry tank, and then perform the vacuum suction filtration molding operation, using the negative pressure formed ...

Embodiment 2

[0030] The present invention proposes a new type of wax core molding carbon fiber molding technology, which includes the following steps:

[0031] S1: First, prepare raw materials, prepare 50 parts of ceramic fiber, and the content of alumina in this kind of ceramic fiber is 60%, and the content of dispersant is 10 parts. This kind of dispersant is an inorganic dispersant, and the inorganic dispersant can be used in the fiber Improve the gloss of the fiber and reduce the overall viscosity of the fiber during molding. 4 parts of binder, 4 parts of additives, remove the above materials, according to the ratio of ceramic fiber, dispersant, binder and additive 10:2:1:1, Mix into a slurry at a temperature of 30°C;

[0032] S2: Take an appropriate amount of the slurry in step S1, and then use a non-clogging pump to drive into the molding tank, immerse the perforated mold into the slurry tank, and then perform the vacuum suction filtration molding operation, using the negative pressure fo...

Embodiment 3

[0042] The present invention proposes a new type of wax core molding carbon fiber molding technology, which includes the following steps:

[0043] S1: First, prepare raw materials, prepare 30 parts of ceramic fiber, and the content of alumina in this kind of ceramic fiber accounts for 60%, and 6 parts of dispersant. This kind of dispersant is an inorganic dispersant, and the inorganic dispersant can be used in the fiber Improve the luster of the fiber and reduce the overall viscosity of the fiber during molding. 3 parts of binder, 3 parts of additives, remove the above materials, and make the ratio according to the ratio of ceramic fiber, dispersant, binder and additive 10:2:1:1. Mix into a slurry at a temperature of 25°C;

[0044] S2: Take an appropriate amount of the slurry in step S1, and then use a non-clogging pump to drive into the molding tank, immerse the perforated mold into the slurry tank, and then perform the vacuum suction filtration molding operation, using the negati...

Abstract

The invention discloses a novel wax core forming carbon fiber forming technology. The technology comprises the steps of S1, firstly, preparing a raw material; S2, taking the proper amount of slurry inthe S1, and using a non-blocking pump for pumping the slurry into a forming groove; S3, taking the proper amount of a carbon fiber finished product in the S2, and adding the finished product into a pre-forming mold; S4, taking a finished product in the S3 for heating treatment, and using a heating plate for heating a gum dipping carbon fiber; and S5, carrying out quality testing treatment on thefinished product obtained in the S4. The method is clear in step, the process is simple, in the specific implementation operation process, the number of used devices is small, production cost can be greatly saved, the produced finished product is reliable in quality, and the subsequent producing machining is facilitated.

Description

Technical field [0001] The invention relates to the technical field of fiber molding, in particular to a new type of wax core molding carbon fiber molding technology. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up organic fibers such as flake graphite microcrystals along the axial direction of the fiber, after carbonization and graphitization. Carbon fiber is "flexible on the outside and rigid on the inside". Its mass is lighter than that of metal aluminum, but its strength is higher than that of steel. It also has the characteristics of corrosion resistance and high modulus. It is an important material for national defense, military and civilian use. Carbon fiber needs to go through the step of carbon fiber molding in the preparation process, but the traditional carbon fiber molding method has a single ste...
