摘要：

At present, China has made great breakthrough in the development and production of high-performance carbon fiber. In this paper, different batches and grades of domestic ZT7H carbon fibers were selected and processed for desizing and sizing, and then carbon fiber reinforced epoxy resin composites were prepared. The effect of domestic H1 sizing agent on the surface morphology and micro-interface properties of ZT7H carbon fibers was explored, as well as the differences in interface performance of composites made from different grades of carbon fibers. Studies have shown that H1 sizing agent increases the surface roughness and polar component content of carbon fibers, enhancing the micro-interface mechanical properties of the composite before and after hygrothermal treat. At the same time, the weaving method of carbon fiber fabric has a great influence on the static mechanical properties and interface properties of its composites. Experiments have proved that the performance of domestic ZT7H carbon fiber has exceeded Toray T700 carbon fiber, but its product performance stability still needs to be improved. © 2021, Editorial Office of Acta Materiae Compositae Sinica.
