Embodiment 1

[0038] Example 1 Carbon fiber composite material tank and its preparation method

[0039] 1. If figure 1 As shown, the tank body of the tank in this embodiment is made of carbon fiber composite material, including a metal inner layer 1 , a local reinforcement layer 2 , a reinforcement layer 3 and an outer protective layer 4 . The thickness of each layer is: metal inner layer 3mm, local reinforcement layer 10mm, reinforcement layer 15mm, outer protective layer 3mm.

[0040] 2. If figure 2 Shown, the preparation method of the tank of the present embodiment comprises the following steps:

[0041] 1) According to the structure design of the tank, the metal inner layer is made of cemented carbide material; the metal inner layer is treated as a base, and the surface of the inner layer is polished and degreased by sandblasting.

[0042] 2) Spread the twill fabric woven by Toray T700 type 24K carbon fiber and the vinyl resin glue containing the initiator cyclohexanone peroxide (CH...

Embodiment 2

[0045] Example 2 Carbon fiber composite material tank and its preparation method

[0046] 1. If figure 1 As shown, the tank body of the tank in this embodiment is made of carbon fiber composite material, including a metal inner layer 1 , a local reinforcement layer 2 , a reinforcement layer 3 and an outer protective layer 4 .

Abstract

The invention discloses a carbon fiber composite. The carbon fiber composite comprises a metal inner layer, a local reinforcement layer, a reinforcement layer and an outer protection layer in sequence, wherein the reinforcement layer is formed by preferably winding large-tow carbon fibers. The invention also discloses a preparation method of the carbon fiber composite. The invention further discloses a tank prepared from the carbon fiber composite. The tank can be used for carrying liquid, powder, gases, pulp and other substances. The carbon fiber composite and the tank have the beneficial effects that compared with the traditional metal tanks, the tank prepared from the carbon fiber composite is lightened by more than 50%; the carrying capacity of a tank car can be obviously improved, and fuel consumption and carbon dioxide emission can be reduced; and the tank has the double effects of increasing the operating profits and reducing the environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a carbon fiber composite material, a preparation method thereof and a tank prepared therefrom. Background technique [0002] Tank trucks are tank-shaped transport vehicles used to transport various liquids, liquefied gases, powdery and slurry goods, etc. These goods include gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, etc. , various acid-base liquids, cement lead oxide powder, etc. Tank trucks play an important role in transportation, accounting for about 18% of the total number of trucks. The materials used in the existing tank trucks are mainly metal. To ensure the carrying capacity of the tank trucks, the tank trucks made of steel have a design capacity of 11m 3 , the rated capacity is less than 9.6m 3 , the minimum wall thickness shall not be less than 5mm (with additional corrosion), and as the load cap...
