| Abstract: | the influences of modified BMI composition on the glass transition temperature (T g).Thermal decomposition temperature (T d) and impact strength were investigated. The toughened BMI resins maintain high T g and T d.The impact strength of above modified BMI resin can reach as high as 18.9kJ/m 2,and the morphologies of the fracture were analyzed by scanning electron microscope(SEM) technique. |
