Abstract： To enhance the mechanical properties of woven carbon fiber composites and promote their application in practical engineering， an optimization approach by introducing graphene oxide （GO） and adjusting its mass fraction is proposed. Woven carbon fiber composites with GO mass fractions ranging from O to 0.5% were fabricated using vacuum impregnation and hot-pressing processes. Thre-point bending tests were performed，and the micro-fracture morphology was characterized by scanning electron microscopy. Concurrently，a representative volume element model was constructed and imported into simulation software for three-point bending simulation analysis. The results show that as the GO mass fraction increases from O to 0.5% ，the ultimate bending load of the material increases from 150N to 292N ，representing an improvement of nearly 95% The bending strength and modulus reach optimal values at a GO mass fraction of 0.5% ， measuring 164.71MPa and 9.97GPa ， respectively，which are 93.02% and 49.47% higher than those of samples without GO. The experimental and simulation results exhibit consistent trends and good agreement，indicating that the addition of GO significantly influences the microstructure and mechanical properties of woven carbon fiber composites，with the most pronounced effect observed at a GO mass fraction of 0.5% . This study provides data support and theoretical reference for the design and fabrication of high-performance carbon fiber composites.
