| 摘 要： | 作者用称重法研究了化学介质在玻璃纤维增强塑料(FRP)中的扩散过程,即M_t～t~(1/2)曲线。发现随所用的化学介质、环境温度,或FRP中树脂含量等因素的变化,其扩敞过程与Fick定律发生四种类型的偏离。根据这些偏离的类型可预估FRP的耐腐蚀性能。当化学介质和FRP的结构组成已经确定时,还可求出扩散系数和扩散活化能。

| Abstract: | The diffusion process(M_t～t~(1/2) curves)of chemical media in glass fiber einforced plastics(FRP)was investigated by gravimetrie method. With variation in chemical media, environmental temperature and resin content of FRP, four kinds of deviation from Fiek law were observed. The corrosion resistance of FRP in different chemical media bears some relationship to the mode of diffusion and can be roughly estimated from the latter. When the chemical medium and components of FRP have been fixed, the diffusion coefficient and diffusion activation energy can be determined. |
