Abstract

In the present paper, a series of novel hybrid configurations were designed and tested in order to improve the energy absorption and impact resistance of carbon fibre composites under static indentation. All three hybrid configurations: glass/carbon hybrid with glass on the impact side, carbon/glass hybrid with glass on the rear side and interlayered glass/thin carbon hybrid, showed significant improvements in energy absorption in static indentation compared to the monolithic carbon layup, although the failure mechanisms were different from case to case. The interlayered glass/thin carbon has shown the highest peak load for penetration initiation and energy absorption, attributed to the fibre fragmentation in the thin carbon layers and stable fibre pull-out.
