Air bubbles and racing flows threaten quality in polymer manufacturing

AI Insight

This study employs three-dimensional numerical simulations to investigate race-tracking and air entrapment during polymer filling processes in manufacturing. Race-tracking occurs when fluid preferentially flows along mold walls or boundaries rather than uniformly through the material, while air entrapment refers to air bubbles becoming trapped in the polymer matrix during filling. The research analyzes how these phenomena affect the quality of polymer composite parts and identifies critical process parameters that influence their occurrence.

Why it matters

Understanding and controlling race-tracking and air entrapment is essential for manufacturing high-quality polymer composite components used in aerospace, automotive, and marine industries. The findings can help optimize manufacturing processes to reduce defects, minimize material waste, and improve the mechanical properties and structural integrity of composite parts.
