Carbon fiber is obtained by carbonization and pre-oxidation of polyacrylonitrile at high temperature, and its carbon content is as high as 90%, which is an emerging high-performance material. Carbon fiber not only has the inherent characteristics of carbon element, but also has the soft processability of carbon fiber. The aramid fiber is made of aromatic compounds as raw materials by polycondensation spinning, with high strength, good impact resistance and fatigue resistance. Both are representatives of emerging materials, so who is better to compare?
Carbon fiber and aramid fiber resin are lightweight, high-strength, corrosion-resistant, high-temperature resistant and impact-resistant materials. Carbon fiber conductivity is good, and aramid fiber insulation is good, carbon fiber material has high strength, brittleness, after being crushed by serious external impact, the entire carbon fiber product needs to be replaced, and aramid fiber is a plastic material, after impact damage, the damage can be repaired.
Carbon fiber and aramid fiber application fields are extensive, carbon fiber is generally not used alone, often with resin, metal, ceramics and other materials composed of carbon fiber composite materials, can be used for robotic equipment, civil aircraft components, robotic arms, rail vehicles, CT plates, sports equipment, etc., and aramid fiber application forms UD, fabric, winding and other forms, and rubber has better adhesion. It is suitable for the production of broadband wave transmission materials and large rigid secondary force structural components on civil aircraft components, industrial equipment panels and lightweight composite structures (such as wings, fairings, cabin liners, hatches, floors, cargo compartments and partition walls, etc.), and is also suitable for the production of yachts, rows, high-speed trains and other high-performance mezzanine structures.
The mechanical properties of carbon fiber and aramid fiber are superior, and carbon fiber and aramid fiber can also be used in practical use to make sandwich structure, which can have lighter mass and better strength.
