Process Optimization Of Anode Electrolytic Oxidation Surface Structure Generation Of PAN-based Carbon Fiber And Design Of Its Experimental Device

With the development of society and the development of science and technology,people have more requirements on the material, especially in the high-tech fields. PAN-basedcarbon fiber enjoy light weight,high strength,high specific modulus,high temperature resis-tance,corrosion resistance,abrasion resistance,fatigue resistance,electrical and thermal con-ductivity, and many excellent performances, so the materials are more and more extensive ap-plication in aerospace, transportation tools, wind power generation, sports leisure, buildingreinforcement, national defense and air weapons and equipment, and other fields. PAN-basedcarbon fiber surface structure generated great practical significance to improve the overallperformance of the composite increase with the bond strength of the epoxy matrix.This paper based on the theory of PAN based carbon fiber anode electrolytic oxidationsurface structure formation, optimize the process and design the continuous experiment de-vice.PAN-based carbon fiber anode electrolytic oxidation surface structure generation processhas a mild reaction, good stability, low cost, pollution-free advantages.Processed PAN basedcarbon fiber has good surface groove structure,more oxygen functional groups, less loss intensile strength and so on.The process of generating process by studying PAN-based carbonfibers of the anode electrolytic oxidation surface structure found the electrolysis time t, thenumber of the current size of the I and Current density D and electrolytic field,these parame-ter determines the different PAN-based carbon fiber surface trench structure, the number ofoxygen-containing functional groups is inconsistent.The main contents of this paper are asfollows:(1) PAN-based carbon fiber anode electrolytic oxidation surface structure generationtheory and analysis.The theory is related to the electrochemical theory.This article describesthe existing electrochemical theory, focusing on analysis of the impact and effectiveness ofthe percolation theory and electric double layer theory of fiber bundles experiments.(2)PAN-based carbon fiber experiment based on the principle of electrolytic oxidationsurface structure generation,description of the experimental ideas,preparation of the experi-mental apparatus, the design and manufacture of static experimental platform.(3)PAN-based carbon fiber anode electrolytic oxidation surface structure generation ex-periments and structural analysis of the design of the experimental program, conducted threeexperiments, and its surface morphology was observed by SEM and XPS analysis of the in- fluence of process parameters on the surface structure: the electrolysis time t, the current sizeof the I, the current density D and electrolytic field number.(4)This paper described continuous carbon fiber anodized surface structure generationand sizing experimental device from the perspective of principle, process, structural de-sign.Focuses on the design of key parts of the electrolysis of PAN-based carbon fiber anodeelectrolytic oxidation surface structure generation and sizing experimental device sizing.Thispaper provide continuous PAN-based carbon fiber anode electrolytic oxidation surface struc-ture generation and sizing process experimental device for future researchers,and contribute tothe field of carbon fiber surface treatment.
