Abstract: The aluminum foil mesh samples were anodized in phosphoric acid solutions. The surface microstructure of aluminum foil mesh samples was observed and analyzed. The weather resistance of aluminum foil mesh conducting layer composite was analyzed, including seawater resistance, thermal fatigue resistance and thermal-oxidative aging. The results showed that a porous film was formed on the surface of the anodized foil mesh, and the bonding interface area of aluminum foil mesh and composite material increased. With the increase of seawater corrsion time, thermal fatigue resistance time and thermal-oxidative aging time, the shear strength of double-bonding of aluminum foil mesh conducting layer composite decreased. The anodized aluminum foil mesh had good weather resistance than the non-anodized one.
