Table 1 represents the steel pipe for being the metal of embodiment 1～5 and comparative example 1 with the corrosion-resistant composite structural member of composite
It is curved before and after the corrosion-resistant composite structural member corrosion of the adhesive property and metal between fiber composite layer and composite
Qu Qiangdu.
Table 1
From table 1 it follows that the steel pipe of the corrosion-resistant composite structural member of the metal of embodiment 1～5 and composite with
Adhesion strength between fiber composite layer is at least 1.0MPa, and the metal of comparative example 1 is corrosion-resistant multiple with composite
The adhesion strength closed between the steel pipe and fiber composite layer of structural member is only 0.12MPa, well below embodiment 1～5, this
It is because, the metal bump and annular groove of embodiment 1～5 substantially increase the bonding between steel pipe and fiber composite layer
Performance, and the increase of metal bump height and the increase of annular groove width can improve adhesive property.And while be provided with
The adhesion strength of the embodiment 1～3 of metal bump and annular groove is strong more than the bonding of the embodiment 4 for being provided only with metal bump
Degree, and metal bump is not provided with, it is not provided between the steel pipe and fiber composite layer of the comparative example 1 of annular groove again
Bonding strength is lost almost.
It can also be seen that being again provided with the embodiment 1～5 and comparative example 1 of fiber composite layer from table 1, implement
The bending strength of 1～embodiment of example 5 is but significantly larger than comparative example 1, and fiber composite layer itself can just improve overall
Structural strength, and as the thickness of fiber composite layer is improved, metal is whole with the corrosion-resistant composite structural member of composite
Body structural strength can also be lifted, and the bending strength of comparative example 1, well below embodiment 1～5, this is to should be, comparative example 1
Adhesion strength between steel pipe and fiber composite layer is poor, in deformation process between steel pipe and fiber composite layer
Jing departs from, and has no idea to bear load again.
It can also be seen that after the corrosion-resistant composite structural member corrosion of the metal and composite of embodiment 1～5 from table 1
Bending strength fall less than 25%, and after the corrosion-resistant composite structural member corrosion of the metal of comparative example 1 and composite
Bending strength but significantly decline, have dropped 32%, this is because the corrosion resistant of the metal of embodiment 1～5 and composite
There is preferable adhesion strength between the steel pipe and fiber composite layer of erosion composite structural member, so as to improve to a certain extent
The decay resistance of metal and the corrosion-resistant composite structural member of composite.
It can also be seen that the metal of the embodiment 1～4 for being provided with polymer waterproof layer is resistance to composite from table 1
Corrosion composite structural member with the embodiment 5 for being not provided with polymer waterproof layer comparatively, steel pipe and fiber composite layer it
Between there is more preferable adhesion strength, and the corrosion-resistant composite structural member of metal and composite has more preferable bending strength, says
It is curved with the corrosion-resistant composite structural member of composite that bright setting polymer waterproof layer can also increase metal to a certain extent
Qu Qiangdu.Meanwhile, it can also be seen that relative to the embodiment 5 for being not provided with polymer waterproof layer, embodiment 1～4 from table 1
Bending strength fall after being provided with the metal of polymer waterproof layer and the corrosion-resistant composite structural member corrosion of composite
It is less, this is because fibrous composite is more crisp, and passes through setting polymer waterproof layer and can send out in the composite layer on surface
In the case of raw destruction, internal metal structure is not corroded by water, to strengthen the corrosion-resistant composite junction of metal and composite
The water resistance of component, it is corrosion-resistant with the corrosion-resistant composite structural member of composite so as to improve metal to a certain extent
Performance.
