Embodiment 1
[0082] This embodiment adopts the calculation method of the epoxy resin adhesive storage life of the present invention, the failure condition of the epoxy resin is that the tensile shear strength P is less than 20.5Mpa condition, according to the fitting adhesive shear strength change rate of the model, obtain four The failure times under the accelerated test temperature are: 393.15K (120℃) failure life is 318.77 days, 413.15K (140℃) failure life is 120.15 days, 433.15K (160℃) failure life is 52.62 days, 453.15K (180°C) failure life is 24.76 days.
[0083] According to the relationship between epoxy resin failure life and temperature The results obtained by fitting the least squares method are as follows: image 3 as shown in image 3 Shown is a schematic diagram of the agreement between the storage life obtained by the method of the present invention and the actual measured value in Example 1; wherein a=1.251×10 6 , b=1626.395, c=-12.369, the goodness of fit is 99.996%, and...
