3K carbon fiber coiled pipe It is a high-strength, lightweight composite product with excellent mechanical properties. 3K will be introduced in detail below Carbon fiber coiled pipe The production process of.

Step 1: Raw material preparation

The raw materials for making 3K carbon fiber reels mainly include carbon fiber cloth, epoxy resin and hardener. Carbon fiber cloth is made of 3K carbon fiber yarn, with high strength and wear resistance. Epoxy resin and hardener are commonly used adhesives for making composite materials.

Step 2: cloth pretreatment

Cut the carbon fiber cloth to the desired shape, and then preheat it with a hot-air gun to remove the primer and resin with excessive fiber. During preheating, the temperature and time shall be controlled to avoid overheating or prolonged heating.

Step 3: Prepare epoxy resin impregnating material

The epoxy resin and hardener are mixed according to a certain proportion and stirred evenly to make impregnating material. At the same time, certain fillers (such as silica gel, silicon dioxide, etc.) should be added to the impregnating material according to the specific needs to improve the performance of the composite.

Step 4: cloth impregnation

Put the pretreated carbon fiber cloth into the impregnating material to ensure that the carbon fiber cloth absorbs resin evenly. In the process of impregnation, attention should be paid to controlling the impregnation time and the temperature of impregnating material to ensure the impregnation effect.

Step 5: Cascade

The impregnated carbon fiber cloth is stacked together to form a layered structure of coiled pipes. In order to improve the mechanical properties of the composites, attention should be paid to the direction and overlapping mode of the carbon fiber cloth during the stacking process.

Step 6: Hot pressing

Put the stacked coils into the hot press, apply certain pressure and temperature, and conduct hot pressing treatment. The purpose of hot pressing is to further solidify the resin under the action of high temperature and high pressure, so as to improve the mechanical properties of the composite.

Step 7: Trimming

Trim the hot pressed coil to remove excess resin and * *. Trimming methods usually include cutting, grinding and surface coating.

Step 8: Test

The fabricated 3K carbon fiber coiled pipes were tested, including appearance quality, dimensional accuracy and mechanical properties. Common inspection methods include visual inspection, measurement and tensile test.

Through the above detailed introduction, we believe that you have a more comprehensive understanding of the production process of 3K carbon fiber reels. With its excellent mechanical properties and lightweight characteristics, 3K carbon fiber coiled pipe has a broad application prospect in aerospace, automobile manufacturing and other fields.
