Study on Carbon Fiber Surface Treatment and Adhesion Properties of Its Composite Patch Adherent to Aluminum Alloy
The surface of carbon fiber was treated by low temperature plasma method firstly. Then carbon fiber composite patches were prepared using the fiber and epoxy adhesive. There were longitudinal dense flutings generated on the surface of carbon fiber and surface roughness of carbon fiber increased after low temperature plasma treatment analyzed by SEM, AFM and mechanical tensile-test. The mechanical mosaic action between fiber and organic matrix was promoted and the composite materials repair for aluminum alloy sheet with edge crack did its work. The optimum process of low temperature plasma method showed that the etching extent of surface of carbon fiber increased as process temperature increased. It wasnt make obvious different when prolonging process time at 150℃. However, the etching extent could be enhanced when prolonging process time at 200 ℃.The optimizing process was 150℃×1.5h.
