introduction

3K carbon fiber coiled pipe It is a new type of composite pipe, which has the characteristics of light weight, high strength and corrosion resistance, and is widely used in aerospace, automotive, construction and other fields. This article will focus on 3K Carbon fiber coiled pipe To provide reference and guidance.

test method

The tensile test of 3K carbon fiber reels was carried out using a standard tensile testing machine. First, prepare a sample of 3K carbon fiber coiled pipe with a length of 200mm, and measure its diameter and wall thickness. Then, fix the sample on the testing machine, gradually load the force, and record the strain and stress values during the loading process. Finally, the tensile strength and elastic modulus of 3K carbon fiber coiled pipe are calculated according to the experimental results.

Results and discussion

For the 3K carbon fiber coiled tube sample tested, its diameter is 20mm and the wall thickness is 2mm. The tensile test results show that the strain of 3K carbon fiber coiled pipe increases linearly until it breaks during the loading process. At the same time, the stress value also increases with the increase of the loading force.

According to the experimental data, the tensile strength of 3K carbon fiber coiled pipe is 300MPa, and the elastic modulus is 50GPa. This shows that the 3K carbon fiber coiled pipe has high tensile strength and rigidity.

Comparison with other materials

In order to better understand the performance of the 3K carbon fiber coiled pipe Glass fiber tube Compare.

Compared with traditional metal pipes, 3K carbon fiber coiled pipes have higher strength and rigidity, and are also lighter. This makes the 3K carbon fiber coiled pipe have greater advantages in applications with high space restrictions and weight requirements.

Compared with glass fiber tube, 3K carbon fiber tube has higher corrosion resistance and durability. Glass fiber tube will be corroded in some corrosive environments, and 3K carbon fiber tube can maintain its performance well.
