The surface topography of table 2
As it can be seen from table 1 the interlaminar strength for the composite that embodiment 1-10 is provided is higher than in comparative example 1-3
Peel strength, and with the lengthening of ageing time, the peel strength value changes in comparative example 1-3 are more obvious.Wherein implement
Compared with mutually isostructural composite, its interlaminar strength is higher, illustrates in binding agent for example 4 and 5 and embodiment 9 and 10
Its bond effect is more preferable after adding anticorrosion glue, and is less likely to occur to permeate, and interlaminar strength is kept high value.
From table 2 it can be seen that the appearance that composite in comparative example 1-3 is all different degrees of when experiment proceeds to 30 days
The phenomenon of layering and bubble, and the composite in embodiment 1-10 does not occur the above situation, illustrate its anticorrosion ability
It is more excellent.
