Abstract: The effect of anod treatment on the interface adhesion between carbon fibers with DMF cement has been investigated in this work.The experimental results show that the anod treatment is an effective method to increase the interface adhesion of carbon fibers/MDF cement.The strength σ_f and impact energy absorption α_k of untreated carbon fiber reinforced MDF cement composite are lower than those of the matrix.The σ_f and α_k of the composite,in which the carbon fibers are treated by anod treatment,are much greater than those of the matrix,and as a result the anod treatment can considerably increase the carbon fiber/MDF cement interface adhesion.When the content of pitch-based carbon fiber is 2.0wt% and is treated at optimum conditions,the σ_f and α_k and ak of the composite can reach 116.4MPa and 1.63kJ/m²,respectively.
