The Effect of Anodizing on Adhesive Property of Aluminum Foil Mesh and Resin Matrix Composite

The aluminum foil mesh was anodized in the solutions of phosphoric acid and the effect of the anodizing parameters on the adhesive property of the aluminum foil mesh and resin matrix composite were studied. The surface morphology and adhensive property of anodized aluminum foil mesh treated by improved progress were observed and analyzed. The results show that the phosphoric acid volume fraction of deoxidization in optimum process was 16% and time was 6 min, the phosphoric acid volume fraction of oxidization was 16% and time was 23 min. A porous oxidation film was formed on the surface of the aluminum foil mesh, and it helped to increase the interface area of aluminum foil mesh and composite, make a good interface effect and improve the adhesive strength, the shear strength was 14.66% larger than that of the non-anodized one. The anodized aluminum foil mesh had better corrosion resistance.
