  • A viscoelastic material meeting the manufacture process requirements of the embedded high-temperature co-cured composite damping structure was studied by using orthogonal experiment method, and the brush coating process is proposed to replace the membrane forming process in manufacturing the viscoelastic material film. The embedded co-cured composite(T300/QY8911) damping specimens are manufactured by employing these two processes respectively. And then the interlamination shear was measured for each specimen. The relationship of the interlamination shear property with viscoelastic film thickness was obtained by the experimental study. The experimental data indicate that the brush coating process can improve the interlaminar bonding force of the embedded co-cured composite damping structure by more than 10%, the thicker the damping film is, and the higher the bonding force increases. The failure surfaces show that the brush coating process makes the interface forming interpenetrating polymer network structures between viscoelastic film and composite.
