At silicone liquid rubber contents < 10 wt% significantly improved toughness has been achieved without adversely affecting thermal and mechanical properties. Fractographic and interferometric methods have been applied to study crack propagation in such siliconemodified resins.enblendepoxy resinfractureliquid rubberrubber tougheningsiliconestrengthtoughness531620660journal article
