The present work investigates the effect of polyimide and poly(amic acid) content on the properties of epoxy resin. Charpy impact strength increased by 80% and 70% with the addition of 10 wt.% poly(amic acid) and 15 wt.% polyimide, respectively. However, the flexural strength was improved by 95% and...
