The ES-U3160 reinforced fabrics with toughening function were prepared by adhering the Ex-situ elasticizer polyethersulphone homogeneously on reinforced fabrics according to Ex-situ toughening technology. Composites were prepared by RTM process taking U3160 and ES-U3160 fabrics as reinforcement. The toughness properties of U3160/3266 composites by Ex-situ toughening were investigated through interlaminar fracture toughness test and low-velocity impact test. The results showed that compared with U3160/3266 composites, ES-U3160/3266 composites had higher GIC value, GIIC value and CAI value. Based on Ex-situ toughening concept, the thermoplastic/thermosetting co-continuous phase was formed, which dramatically improved the interlaminar fracture toughness, impact damage resistance and impact damage tolerance.
