Fiber misalignment appears in continuous fiber-reinforced thermoplastic prepreg tape lamination

Fiber orientation deviation exceeds the allowable angle during lamination. This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Process factor: The prepreg tape rotates and shifts during placement or movement, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: Positioning is not precise enough, 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) Process control: Use automated placement equipment (ATL/AFP) to precisely control fiber angles, Establish an online monitoring mechanism, set upper and lower parameter limits, and implement alarm management. (2) Material selection: After lay-up, use ultrasonic or vision systems to detect fiber direction., Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (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.
