Abstract Microwave curing has a tremendous potential to be used as an alternative to other thermal curing processes due to its shorter curing time and lower consumption of energy. Current research investigates the damping and dynamic mechanical characteristics of core-shell polymer (C/SH) particle modified glass fibre prepreg (GFRP) manufactured using microwave irradiations. The addition of C/SH particles has shown a significant improvement in damping and dynamic mechanical properties. The optimal areal weight per interface (AWI) for C/SH particles was established as 40 gsm. With this optimal addition, the laminates showed a 21.5% increase in mechanical loss factor, tan δ, and 52.7% in the vibration damping capability as noticed from dynamic mechanical and the forced vibration tests respectively. The underlying reasons for the improvement in properties with the addition of C/SH particles are also deliberated in this paper.

微波辐射固化的核壳颗粒改性玻璃环氧树脂预浸料的减振和动态力学特性

摘要 微波固化具有固化时间短、能耗低等优点，具有替代其他热固化工艺的巨大潜力。目前的研究调查了使用微波辐射制造的核壳聚合物 (C/SH) 颗粒改性玻璃纤维预浸料 (GFRP) 的阻尼和动态机械特性。C/SH 颗粒的添加显示出阻尼和动态机械性能的显着改善。C/SH 颗粒的最佳每界面面积重量 (AWI) 为 40 gsm。通过这种最佳添加，层压板的机械损耗因子 tan δ 增加了 21.5%，减振能力增加了 52.7%，分别从动态机械和强制振动测试中看出。
