Metal Ion Implantation

composite laminates, metal ion implantation, low-velocity impact damage, BVID Abstract. Metal ion implantation was carried out on composite laminates to modify the surface properties, so that after low-velocity impact barely visible impact damage (BVID) was easy to realize. Surface topography of laminates was observed by SEM. Microhardness and drop-weight impact was tested on composite laminates. The results showed that after metal ion implantation microhardness of laminates increased obviously and resin was easy to generate plastic deforming. Dent depth had been improved so as to realize visible impact damage more easily. And compression-after-impact (CAI) had not decreased. Comparison with Ti ion implantation, Cu ion implantation had better influence on realizing visible impact damage (VID).

Core Materials

Sandwich composite laminates structure is a classic application of composite material on actual aircraft structural. Dealing with low-velocity impact damage and residual compressive strength of sandwich composite laminates, explicit finite element method of ABAQUS/Explicit software was adopted to simulate low-velocity impact and compression process. Impact response and invalidation on compression between sandwich composite laminates with different core materials and regular composite laminates were compared. The simulation results indicated that softer core materials can absorb more impact energy, reduce the structure damage and enhance the residual compressive strength after impact.
