Purpose of this study is to improve the inter-laminar fracture properties of the carbon fiber reinforced plastic laminates by addition of fine particle to brittle matrix resin. In this study, vinyl ester was used for the CFRP matrix and two types of particle, alumina and silicon rubber were used for the modifier. Three point bending test, DCB test and ENF test was conducted to investigate the effect of mechanical properties of particle incorporated specimen. The mechanism of the difference in fracture behavior for these particle modified laminates was discussed on the bases of in-situ observation and fracture surface observation.
