The following are the main limitations of traditional process:

Multi-step process complexity: Traditional preparation process usually includes multiple separate steps, such as fiber heat treatment, impregnation, preforming, hot pressing, etc.; multiple steps require manual operation, increasing operation error and labor intensity, making it difficult to achieve consistency in large-scale production.

[0004] 2. Limitations of heat treatment: Heat treatment process usually needs to be carried out in high-temperature environment to remove the infiltrant on the surface of the fiber. This process takes a long time, reducing the overall production efficiency; high-temperature treatment requires a large amount of energy, increasing production cost and environmental burden.
