Synergistically optimizing interlaminar behavior of CFRP composites by simultaneously applying amino-rich graphene oxide to carbon fiber and epoxy matrix

In this study, graphene oxide (GO) with long flexible amino-rich structure, i.e., GO-COOH-T403, was prepared by grafting trifunctional polyether amine (T403) to the surface of in-situ carbonylated GO. The amino-rich GO nanosheets were employed to modify epoxy resin and fabricate multiscale carbon fiber (CF), respectively. Basing on that, carbon fiber reinforced polymer (CFRP) composites with superior interlaminar behavior were obtained via...
