What are the superior properties of chopped carbon fiber? Take a look!

Short-cut carbon fiber is made by chopping carbon fiber filaments through a fiber cutter. The basic performance depends mainly on the properties of the raw material, carbon fiber filament.

Short-cut carbon fiber is a new material with higher strength than steel, lower density than aluminum, stronger corrosion resistance than stainless steel, high temperature resistance to heat-resistant steel, and electrical conductivity like copper. It has many valuable electrical, thermal and mechanical properties. .

Each carbon fiber is made up of thousands of smaller carbon fibers with a diameter of about 5 μm to 8 μm. The carbon fiber at the atomic level is very similar to graphite, and is composed of a layer of carbon atoms arranged in a hexagonal shape. The difference between carbon fiber and graphite is the layer-to-layer connection. Graphite is a crystal structure in which the interlayer connection is loose, and the carbon fiber is not a crystal structure, and the interlayer connection is irregular, which prevents slippage and enhances the strength of the material.

Generally, the density of carbon fiber is 1750 kg/m3, the heat conductivity is high, but the power transmission capacity is low, and the specific heat capacity of carbon fiber is also lower than that of copper. When heated, the carbon fibers become thicker and shorter. Although the natural color of carbon fiber is black, scientists can dye it in different colors.

Through the above description, we have deepened our understanding of chopped carbon fiber.
