How to Choose CF30 PA12 or LCF30-PA12?

Carbon Fiber Length
– Long Carbon Fiber Reinforced PA12: The carbon fibers are relatively long, generally in the millimeter range. The long carbon fibers can form a relatively continuous reinforcing network structure within the material. 
– Short Carbon Fiber Reinforced PA12: The carbon fibers are short, usually in the micron range. The short carbon fibers are discretely distributed in the PA12 matrix.

Mechanical Properties
– LCF PA12: It exhibits more excellent performance in terms of tensile strength, flexural strength, and impact strength. The long carbon fibers can transfer stress more effectively and impede the propagation of cracks. Therefore, when subjected to large external forces or dynamic loads, it can provide higher strength and toughness to the material, making it suitable for components with extremely high requirements for structural strength and stability, such as some structural components in the aerospace field.
– SCF PA12: Although it can also increase the strength and hardness of the material, the improvement range is relatively smaller compared to long carbon fiber reinforced PA12. However, short carbon fibers perform well in enhancing the dimensional stability and wear resistance of the material. It is suitable for manufacturing some components that require high precision and wear resistance, but have relatively less stringent requirements for absolute strength, such as some small wear – resistant components in automobile engines.

Difficulty of Processing Technology
– Long CF PA12: Due to the presence of long carbon fibers, the material has poor fluidity. During processing such as injection molding and extrusion, higher temperatures and pressures are required, and the requirements for processing equipment are also higher, resulting in greater processing difficulty.
– Short CF PA12: Short carbon fibers have a relatively small impact on the material’s fluidity. Conventional processing techniques and equipment can be used for forming, and the processing difficulty is relatively low.

Notes: 

1. Performance – determining Factor：Carbon fiber length greatly impacts PA12 properties like cf30 pa12. Long fibers form a continuous network, giving long – fiber – reinforced PA12 superior mechanical strength. Short fibers, being discretely distributed, enhance short – fiber – reinforced PA12’s dimensional stability and wear resistance.
2. Processing – application Link：Long – fiber – reinforced PA12, hard to process, is ideal for aerospace parts demanding high performance. Short – fiber – reinforced PA12, easier to process, suits small, wear – resistant automotive engine components.
