Step effect appears at laminate edges

When adding or reducing plies, step-like contours appear at the edges, affecting sealing. 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 number of local reinforcement patch plies is inconsistent with the number of substrate plies, forming thickness steps, This factor affects the '2079851475616104453 and final quality of the product. (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) Implementation measure: Use tapered lay-up at patch layer edges (each layer edge gradually narrows), Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (2) Implementation measure: Make the step slope <1:10, Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (3) Implementation measure: Fill between patch layers with filling material for a smooth transition., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (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.
