A kind of carbon fiber functional composite material and its preparation method and application

Abstract

The invention discloses a carbon fiber functional composite material and its preparation method and application, the surface density of which is 150-300g / m 2 ; Its raw materials include carbon fiber, pulp, oil-water separator and static agent; wherein the mass ratio of carbon fiber to pulp is 5:5 to 6:4; the amount of static agent added is 1 to 3% of the total mass of carbon fiber and pulp; the carbon fiber It is carbon fiber with a carbon content greater than 90%; the preparation method includes the following steps: weigh the raw materials, stir and mix the carbon fiber and pulp, add an oil-water separation agent and mix thoroughly, then add an electrostatic agent, mix again and pass through 150-300°C Serve after baking for 1-2 minutes. Install it under the air filter of the car, and produce a corona discharge effect with positive ions in the air, neutralize the static electricity of positive ions in the engine, make the mixing state of air and fuel more uniform, and improve the combustion efficiency inside the cylinder.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a carbon fiber functional composite material and its preparation method and application. Background technique [0002] Insufficient fuel in the car will cause carbon deposits, which have many adverse effects on the car as follows: 1. Poor acceleration of the car. Carbon deposits reduce the intake passage and reduce the air charge coefficient, which causes the cylinder pressure to increase and the ignition time to be delayed, resulting in a decrease in engine power. 2. The vehicle is difficult to start. Carbon deposits fall into the channel of the intake valve seat, which will cause insufficient cylinder pressure. In addition, the fuel injected during startup is absorbed by carbon deposits, resulting in a thin mixture in the cylinder, and the engine cannot be started normally. 3. Engine idling is unstable. When carbon deposits are attached to the intake ...

AI Technical Summary

Problems solved by technology

[0002] Insufficient fuel in the car will cause carbon deposits, which have many adverse effects on the car as follows: 1. Poor acceleration of the car

Carbon deposits reduce the intake passage and the air charge coefficient, which causes the cylinder pressure to increase and the ignition time to be delayed, resulting in a decrease in engine power

2. The vehicle is difficult to start

Carbon deposits fall into the channel of the intake valve seat, which will cause insufficient cylinder pressure

In addition, the fuel injected during startup is absorbed by carbon deposits, resulting in a thin mixture in the cylinder, and the engine cannot be started normally.

3. The engine idle speed is unstable

When carbon deposits are attached to the intake valve and throttle valve, the engine cannot accurately control the amount of gasoline and air sent to the combustion chamber, resulting in unstable idling of the engine

4. Increased fuel consumption

When carbon deposits are accumulated in the combustion chamber, it is easy to cause knocking, resulting in delayed ignition of the engine, reduced power, and increased fuel consumption by 4-5%.

5. Excessive emission of exhaust gas

Carbon deposits lead to an imbalance in the mixing ratio of gasoline and air, resulting in incomplete combustion of gasoline, increased CO and HC content in the exhaust, and emissions that are not up to standard

6. Engine failure

Second, the mixing of the air-fuel ratio is not good. After the air is polluted, the oxygen required for combustion is not enough

Third, the ignition efficiency of the car itself is reduced. There are often many electrical appliances that use electricity during driving, especially when driving at low speeds, the ignition energy will be reduced.
