Fiber fusing/damage during the lamination process

Excessively high temperature during lamination of high-melting-point thermoplastics (such as PEEK/PEI) causes fiber performance degradation. This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Temperature parameter aspect: The lamination temperature approaches or exceeds the heat resistance limit of the fiber (such as the carbon fiber surface treatment layer), Temperature deviation directly affects the physicochemical state of the material and the reaction progress. (2) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (3) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (4) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Material selection: Select high-temperature resistant reinforcing fibers and treatment agents, Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (2) Process control: Strictly control the lamination temperature not to exceed the heat resistance upper limit of the fiber., Establish an online monitoring mechanism, set upper and lower parameter limits, and implement alarm management. (3) Process optimization: Determine the optimal process parameter window through systematic tests and establish standardized operating procedures. (4) Quality control: Strengthen process monitoring and product inspection, Establish a defect early-warning and traceability mechanism. (5) 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.
