摘要
Abstract
A comprehensive performance of the matrix resin was obtained by introducing vinyl benzyl compounds (N-DVBA) as a modifier 2,2'-( 1,3-phenyl)bis(4,5-dihydro)oxazoline as the toughening agent. DSC(differential scanning calorimetry) ,DMTA( dynamic mechanical thermal analyses) ,SEM( scanning electron microscope) were employed to characterize the structure and performance of the matrix resin. The results indicate that the cured resin had excellent thermal and mechanical properties, such as Tg is 279. 1℃ , its tensile and bending strength is 88. 50 MPa and 133.8 MPa, elongation rate is 3% .dielectric constant^) is 3.79,dielectric loss tans( 1 MHz) is 0.010.关键词
