Carbon is the basic element of life. Both humans and animals belong to the carbon matrix. Carbon in nature also exists in many forms, such as graphite, diamond, coal and so on. Nanofiber filter membrane composite material is a man-made high-quality material with a very high carbon content. It has high temperature resistance, corrosion resistance, stable chemical properties, good thermal stability, light weight and high strength, and it has a wide range of applications in many aspects. , This article is mainly to tell you about its mechanical properties.

The mechanical properties of nanofiber filter membrane composites are reflected in its strength and elastic modulus. Its strength is related to the direction and content of the reinforcing fiber and the degree of bonding between the fiber and the matrix interface. Of course, it also depends on the carbon body. The matrix carbon material is different and the strength is also different. The modulus of nanofiber membrane depends on the direction parallel to the fiber axis and the carbon matrix.

On the parallel fiber axis, the tensile strength and modulus are high, and on the deviation of the fiber axis, the tensile strength and modulus are low. Generally speaking, the tensile strength of the nanofiber filter membrane composite material is greater than 270MPa, and the elastic modulus is greater than 69GPa. Some nanofiber filter membrane composites with superior performance can achieve a strength of over 349MPa and an elastic modulus of 700MPa.

In addition to mechanical properties, the nanofiber filter membrane composite material is also very good in other places. It has very good heat resistance and can withstand high temperatures of about 2000 ℃. As the temperature rises, the strength will not decrease. Its strength has been mentioned above. Although the strength is so high, the density is very low, less than 2.0g/cm3, which is lighter than ceramics. Its friction performance is also very good, not easy to wear, and long service life.
