ABSTRACT

Damping composites with sandwich layer are widely used in the fields of aerospace and high-speed trains. The most fatal defect of traditional damping composites is the poor interfacial adhesion between resin matrix and damping materials. To enhance interfacial bonding performance of traditional damping sandwich composites, the novel glass fiber reinforced damping composites were prepared by designing interfacial reaction between damping polymer and resin matrix. The novel damping materials in this work were fabricated via orthogonal test. The interfacial bonding mechanisms of new type damping sandwich composites were characterized by physical and chemical methods. The maximum shear strength in this paper is 6.2 MPa, which is 81.2% higher than the previous work. It is confirmed that the excellent interfacial bonding property is derived from interfacial chemical interaction between damping polymer and resin matrix according to FTIR and XPS. These results reveal that the novel damping composites possess a broad application potential in aerospace and high-speed trains.

通过引入新型夹心膜改善阻尼复合材料的界面粘结性能

摘要

具有夹层的阻尼复合材料被广泛用于航空航天和高速列车领域。传统阻尼复合材料最致命的缺陷是树脂基体与阻尼材料之间的界面粘合性差。为了提高传统阻尼夹心复合材料的界面粘结性能,通过设计阻尼聚合物与树脂基体之间的界面反应,制备了新型玻璃纤维增​​强阻尼复合材料。本文通过正交试验制备了新型阻尼材料。通过物理和化学方法表征了新型阻尼夹心复合材料的界面结合机理。本文的最大抗剪强度为6.2 MPa,比以前的工作高81.2%。可以确认,优良的界面结合性能是根据FTIR和XPS得出,阻尼聚合物与树脂基体之间的界面化学相互作用所产生的。这些结果表明,新型阻尼复合材料在航空航天和高速列车中具有广阔的应用潜力。
