Dry spots/resin-starved areas
Fenómeno do problema
Local areas of laminated products have insufficient resin exposing white fibers.
This problem is relatively common in lamination molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.
Análise das causas
(1) Process factor: glue application missed or the area over-absorbed resin; this factor affects the '2079851475616104453 and final quality of the product.
(2) Process factor: local layup bridging not fully filled during pressing; this factor affects the '2079851475616104453 and final quality of the product.
(3) Pressure parameter aspect: vacuum bag leakage causing insufficient local pressure, causing the material to fail to fill fully or insufficient densification, resulting in decreased product density and bonding strength.
Solução
(1) Equipment maintenance: visually check glue application coverage during layup; formulate regular inspection and maintenance plans to ensure the equipment is in optimal working condition.
(2) Implementation measures: design reasonable resin flow channels; formulate specific operation plans based on actual production conditions and verify implementation effects.
(3) Equipment maintenance: check vacuum bag sealing., formulate regular inspection and maintenance plans to ensure the equipment is in optimal working condition.
(4) Preventive measures: establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.
Conclusão principal
This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
