Research on formation mechanism of metal foils texture on composites surface
Source abstract
Abstract
Abstract This study investigates the formation mechanisms of metal foil textures on composites surface, focusing on the distinct stripes and patterns observed in areas with layer thickness variations, overlaps, stringer bonding, and curved surface. The primary influencing factors identified include resin flow, fiber compaction, stringer spring-back, and non-normal forces during the curing cycle. Under the combined effects of these factors, metal foils migrate toward the tooling surface, causing the resin film to thin and aggregate among fiber bundles, which results in visible stripes and textures. Through experimental analysis and metallographic observations, this study provides insights into fiber bed movement in composite materials and constitutes the first empirical validation under actual manufacturing conditions of the applicability and correctness of classical theories.
