The continuous lamination process (double-belt laminator) uses precise metering and high-temperature (120–160°C) heat pressing, allowing PU or other foams to form chemical bonds with the facings before full curing, achieving peel strength of ≥0.15 N/mm with high uniformity across the panel. Discontinuous production (cold pressing or vacuum bagging) uses pre-cured cores and adhesive films; bonding strength is greatly influenced by adhesive quantity and pressure uniformity, typically only 0.08–0.12 N/mm, with a tendency for poor adhesion at edges. However, from a structural engineering perspective, for PET or high-strength foam cores, the fatigue performance of discontinuously produced panels can be better due to the toughness of the adhesive film. The choice depends on core type and annual production requirements.
What are the differences in core-to-face bonding strength between continuous and discontinuous composite sandwich panel production?
