摘要
Presents a toughened epoxy risen based on diglycidylether of bisphenol A (DGEBA) cured with ethylene diamine (EDA) and modified with a carboxyl terminated acrylonitrile butadiene (CTBN), studies morphologies with different rubber content and analyses the influence of rubber phase morphology corresponding to different rubber contents on mechanical properties (elastic modulus, uniaxial compression yield stress, shearing strength, uneven tensile strength, critical stress intensity factor K ic and strain energy release rate G ic ) of toughened epoxies.
