Inkjet and gravure printing of conductive patterns for the application in lightweight structures

摘要: Resource efficient manufacturing as well as the avoidance of time and cost intensive fabrication methods play an important role in recent production processes. Sheet to sheet (S2S) inkjet printing as contactless and highly flexible technology and gravure printing suitable for large-area roll to roll (R2R) production combined with production processes like back injection molding or resin transfer molding offer great potential to fulfill the mentioned requirements in the field of smart lightweight applications. The main focus is the S2S and R2R manufacturing of conductive grid patterns as well as sensor arrays on flexible substrates using inkjet and gravure printing combined with infrared (IR) radiation for functionality formation. The conductive patterns are integrated into composite materials by back injection molding or resin transfer molding enabling data communication, sensor applications or power supply in the field of …
