环氧树脂基复合材料的灌封防护性能
Encapsulation Protective Properties of Epoxy Resin Matrix Composites
摘要
Abstract
Aiming at the problem of high-g impact protection of encapsulating materials in embedded mea-surement instruments,resin-based composites with different contents of Carboxylated-terminated liquid acrylonitrile rubber(CTBN)were prepared as encapsulating materials for measurement instruments.The effect of CTBN content on the mechanical properties of the material was studied by a uniaxial compression test.The standard Zhu-wang-tang(ZWT)nonlinear viscoelastic model was used to describe the encapsu-lating material.The penetration overload of the projectile obtained by numerical simulation is decomposed and reconstructed as the loading signal of the instrument.The influence of CTBN content,loading condi-tions and internal structure on the high-g impact of the internal components of the instrument is analyzed.The results show that the stress amplitude on the chip can be effectively reduced by installing the chip away from the center and using high-strength encapsulating materials.By changing the installation position of the chip,the energy of most detail signals can be reduced,and adjusting the content of CTBN in the encapsulating material can reduce the energy of detail signals in a specific frequency band.关键词
