WebNov 21, 2024 · The flexural strength decreased with CTBN content, while the elongation at break increased for the rubber-toughened lignin-based epoxies. On the other hand, the impact strength of the CTBN-toughened lignin-based epoxy increased with the CTBN content. The impact strength reached 37.2 kJ/m 2 at 24.1 wt% CTBN.
