Abstract BaTiO3/bismaleimide/epoxy/glass fiber reinforced composites were prepared using E-glass fiber (E-GF) and silane coated E-glass fiber (SC-EGF) separately as reinforcement. BaTiO3 nanoparticles were prepared by hydrothermal method. Results show that the addition of BaTiO3 nanoparticles has significant effects on the mechanical and dielectric properties of the composite. Both E-GF and SC-EGF reinforced BaTiO3/bismaleimide/epoxy composites with 2 wt percentages of BaTiO3 nanoparticles showed improved tensile strength, flexural strength and dielectric constant and those with 3% showed high dielectric strength indicating this composition is more adaptable for high voltage insulating applications. Dielectric constants and dielectric loss of the fabricated nanocomposites have been obtained at higher frequencies (in GHz) by using Vector Network Analyser at room temperature and was found to be highest for the BMI-Epoxy nanocomposite with 1% weight nanofiller.

用于高压应用的玻璃纤维增​​强双马来酰亚胺/环氧树脂 BaTiO3 纳米复合材料

摘要 采用无碱玻璃纤维(E-GF)和硅烷包覆无碱玻璃纤维(SC-EGF)分别作为增强材料制备了BaTiO3/双马来酰亚胺/环氧树脂/玻璃纤维增​​强复合材料。BaTiO3纳米颗粒采用水热法制备。结果表明,BaTiO3纳米颗粒的加入对复合材料的力学和介电性能有显着影响。含有 2 wt% BaTiO3 纳米颗粒的 E-GF 和 SC-EGF 增强 BaTiO3/双马来酰亚胺/环氧树脂复合材料均表现出改善的拉伸强度、弯曲强度和介电常数,而含有 3% 的那些表现出高介电强度,表明该组合物更适用于高电压绝缘应用。
