Abstract

This work presents an attempt to improve the low velocity impact performance of Carbon/Glass hybrid composites by interleaving with tough polyether sulfone (PES) membranes. The hybrid composite was made of a glass/epoxy block that was sandwiched between two carbon/epoxy blocks. The PES reinforced hybrid composite was compared with an unmodified hybrid composite. Experimental results showed that the PES results in an increase in toughness and can reduce damage propagation in the investigated composite panels during an impact event. Figure 1 shows cross-sectional side view of the impacted samples under different energy levels to reflect the damage status of the samples after the tests. The results showed that for low impact energy levels (6J, 12J and 18J), adding the PES membrane reduced the damage area compared to the virgin laminate by an average of 67%. However, by increasing the impact energy level (24J and 32J), fibre breakage was the dominant failure mode and the PES didn’t have a significant effect on the impact performance. These findings have implications in the design of impact resistant composite parts for civil, wind energy, aerospace and automotive applications.
