Galvanic corrosion appears in carbon fiber laminates

Severe corrosion of the metal occurs where carbon fiber contacts metal inserts. This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Environmental condition aspect: Carbon fiber and metal form a galvanic cell in an electrolyte environment, The production environment affects the stability of materials and processes. (2) Process factor: Carbon fiber acts as the cathode and accelerates metal corrosion, This factor affects the '2079851475616104453 and final quality of the product. (3) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (5) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Implementation measure: Add an isolation layer (glass fiber cloth) between the carbon fiber and metal contact surfaces, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (2) Implementation measure: Apply insulating coating on metal part surfaces, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (3) Material selection: Avoid use in humid environments., Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (4) Preventive measure: Establish sound process control standards and a quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of material, process, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
