Abstract

The ES-U3160 reinforced fabrics with toughening function were prepared by carrying the Ex-situ elasticizer polyethersulphone homogeneously on reinforced fabrics according to Ex-situ toughening technology. ES-U3160/5284 CF reinforced epoxy resin matrix composites were prepared by RTM process taking ES-U3160 fabrics as reinforcement. The effect of polyethersulphone on the impact properties of ES-U3160/5284 composites was investigated through low-velocity impact and SEM tests. The results showed that ES-U3160 fabrics were prepared by coating equipment independently developed, which realized preparation of the high quality, high efficiency and stabilization for ES-U3160 fabrics. CAI value of ES-U3160/5284 composites toughened by polyethersulphone increased by 55%, compared with that of U3160/5284 non toughening composites, and the impact resistance ability of composites was improved effectively. Due to the addition of polyethersulphone, the phase version of polyethersulphone and 5284 epoxy resin occurred in the interplay of composites. This structure improved the damage resistance and damage tolerance of composites, which was the main reason improving the toughness of composites dramatically.
