Weight and Rigidity of Paper Machine Doctor Blades

Carbon fiber composite doctor blades feature low density and light weight, with a density of only 1.4–1.6 g/cm³, much lower than steel and stainless steel blades. They greatly reduce the load on the doctor mechanism and dryer cylinder, lower bearing and transmission stress, and save energy consumption. Meanwhile, the material has high specific strength and rigidity, maintaining excellent bending and deformation resistance without sacrificing weight. It avoids vibration and bending during operation, ensuring uniform pressure across the entire width. It achieves lightweight and energy-saving without losing rigidity or stability, effectively protecting the cylinder and improving running stability, making it ideal for high-speed paper machines.
