How to classify and test carbon fiber powder?

carbon fiber powder are generally distinguished by different alkali metal oxide contents, which are generally referred to as sodium oxide or potassium oxide. In the glass raw material, it is introduced by a substance such as soda ash, thenardite, feldspar or the like. Alkali metal oxide is one of the main components of ordinary glass, and its main function is to lower the melting point of carbon fiber. However, the higher the content of alkali metal oxide in carbon fiber powder, the lower its chemical stability, electrical insulation properties and strength. Therefore, for glass fibers of different uses, different glass components containing alkali are used.

Due to the difference in raw material, modulus, strength and final heat treatment temperature, carbon fibers with different characteristics are produced. The former is hard and brittle and is often used for composite materials, and soft and supple is often used for textiles; the latter is mostly used for engineering materials. Due to the increasing use of carbon fiber and its characteristics, the urgency of the test of the strong tensile properties of carbon fiber powder is before us. The tensile strength test is destructive. The sample is not recoverable after the test, and it is very fragile after the carbon fiber powder is separated into single fibers. Therefore, in each test, careful and patience should be required, and the sample should not be caused before the test. damage.
