The bismaleimide composite laminates were toughened via "Ex-situ" toughened technique. Then the toughened and non-toughened composite laminates were tested by using the quasi-static indentation and compression after impact, and the damage of laminates was also investigated by ultrasonic C-scan and deply. The results indicate that the thermoplastic resin/thermoset resin bicontinuous structure forms in the interlayer of the toughened bismaleimide laminates. The special structure can inhibit the damage area of the toughened laminates and improve the damage resistance of laminates, resulting in a more apparent dent depth on the laminates surface. In addition, the damage tolerance of laminates is also improved.
