摘要
通过系统地研究几种国产复合材料的吸湿行为 ,获得了描述湿气在其中扩散的基本参数 ,如平衡湿含量Mm,Mm 与相对湿度φ关系中的常数 a和 b,沿板材厚度方向上的一维湿扩散系数 Dx 以及 Dx 与温度关系中的常数ΔE(湿扩散活化能 )和 D0
The moisture diffusion behavior of several types of domestic polymer matrix composites was studied and their basic moisture diffusion parameters were obtained, such as the equilibrium moisture content, the constants in the relationship between equilibrium moisture content and relative humidity, the moisture diffusion coefficient in the direction of laminate thickness, the active energy of moisture diffusion and in the relationship between moisture diffusion coefficient and temperature. These parameters can be used to realize accelerated wet hot aging for polymer matrix composites, in which the relationship among temperature, humidity and time is emphasized.
