Fiber Materials for Automotive and Aerospace

In the automotive and aerospace fields, fiber materials mainly play a role in the form of fiber-reinforced composite materials to meet high-performance requirements, especially lightweight. Alfa Chemistry provides customers with fiber solutions for automotive and aerospace applications, according to techno-economic requirements or considerations.


In the automotive and aerospace fields, the lightweight design and development of structural materials is a key issue and trend. Lightweight refers to the integrated application of structural lightweight design and manufacturing with various lightweight materials under the premise of ensuring the use, safety performance and cost control requirements, so as to reduce the quality of equipment as much as possible, thereby improving power performance and reducing energy consumption. Therefore, high-performance fiber composites, especially carbon fiber composites, are excellent candidates as lightweight structural materials.

Fiber Composite Solutions

  • Carbon Fiber Composite Material
    Compared with other high-performance fibers, carbon fiber has very excellent mechanical properties with the highest specific strength and specific modulus, whose specific gravity is less than 1/4 of that of steel, and whose tensile strength is 7-9 times that of steel. Even in a high-temperature inert environment of 2000 °C, the strength of carbon fiber will not decrease. It has light weight, high strength, strong designability, high damping, high temperature resistance, friction resistance, corrosion resistance, impact resistance, fatigue resistance and other excellent properties. Therefore, in the field of automotive manufacturing, carbon fiber composite materials have been developed to replace traditional metal materials due to the above advantages. In the field of aerospace, as a structural material, it should have light weight, high strength, high reliability and stability, and epoxy carbon fiber composites have become indispensable materials.
  • Glass Fiber Composite Material
    Glass fiber reinforced plastics (FRP) based on resins are light in weight, high in strength, thermal insulation, sound insulation, waterproof, easy to color, and easy to form. They have been used to manufacture automobile bodies and various accessories, achieving the effect of reducing self-weight and improving vehicle weight utilization factor.
  • Natural Fiber Composite Material
    Natural fibers, including bamboo fiber, hemp fiber, wood fiber, cotton fiber, etc., show the advantages of environmental friendliness and renewability. For example, bamboo fiber-reinforced composite materials show the properties of light weight, high strength and high stiffness. The automotive interior panels prepared by it are not easy to be damaged due to the unique toughness of bamboo fiber in the event of an accident, and the quality of the finished product can be reduced by 20%. Wood-plastic composites obtained by adding flax fibers to polymers as reinforcing fibers can be molded or injected to make automotive parts such as doors and seats.
