High-performance lightweight structures with Fiber Reinforced Thermoplastics and Structured Metal Thin Sheets

摘要

A heavy-duty multi-material-design (MMD) can be realized through the combined use of structured sheet metal and reinforced plastics (FRP). To exploit the high lightweight potential of the various material groups within a multi-material system as efficient as possible, a material-adapted and particularly fiber adjusted joining method must be applied. The present paper primarily focuses on the manufacturing and mechanical testing of novel multi-material joints with structured sheet metals and carbon fiber reinforced thermoplastics (CFRP). For this purpose the applicability of the new Flow Drill Joining (FDJ) method, which was developed for joining of heavy-duty metal/composite hybrids, was investigated.
