Embodiment 1

[0048] Step 1: Take 25ml of nitric acid and 75ml of sulfuric acid respectively, pour them into a beaker and mix them evenly, add 2.0018g of carbon nanotubes, place them at 80°C for 2 hours, wash and filter with a large amount of deionized water and place them in a freeze dryer lyophilized, labeled as oxidized carbon nanotubes;

[0049] Step 2, measure 100 mL of absolute ethanol, and weigh 1.0002 g of carbon nanotubes to configure a 1 mg / mL carbon nanotube suspension. At the same time, in order to improve the conductivity of the solution, add 0.0025 g of Mg(NO 3 ) 2 ·6H 2 O, placed under ultrasonic dispersion for 30min;

[0050] In step 3, TA2 that has been sandblasted and NaTESi anodized in turn is used as the cathode, and another TA2 of the same size is used as the anode. The parameters of the NaTESi anodization process are as follows: the pole spacing is 1.5 mm, the voltage is 10 V, and the time is For 10 minutes, the NaTESi electrolyte components are sodium hydroxide 300...

Abstract

The invention discloses a preparation method of a carbon nanotube reinforced fiber metal laminate, and belongs to the field of composite material preparation. According to the method, carbon nanotubes are deposited on titanium plates subjected to different surface treatment through electrophoretic deposition, absolute ethyl alcohol is adopted as a dispersion solution of the carbon nanotubes, and the stability of suspension liquid is improved by oxidizing the carbon nanotubes through mixed acid. According to the preparation method, the compatibility of the surfaces of the titanium plates and resin is improved, and the carbon nanotubes can be well embedded into the resin and the grooves in the surfaces of the titanium plates, so that the interface performance of the fiber metal laminate is improved, the preparation process is simple, and the time used in the deposition process is short. The method is not limited to stable titanium alloy surfaces, and can also be used for bonding metal with complex structures and resin.

Description

technical field [0001] The invention belongs to the field of composite material preparation, in particular to a method for improving the performance of the metal / resin matrix interface in fiber metal laminates. Background technique [0002] Traditional metal materials have poor fatigue performance; although the unidirectional mechanical properties of fiber-reinforced resin-based composite materials have been improved, the interlayer bonding performance is not strong after multi-layer lamination, which easily causes material fracture and limits its application range. Therefore, we need a new type of composite material, which can not only retain the advantages of the two materials, but also make up for their respective defects. Fiber metal laminates (FML) are developed under this demand. [0003] Since FMLs are a kind of ultra-hybrid composite materials, interfacial research has always been crucial for their further development and application. For graphite fiber reinforced t...
