Abstract :This paper deals w ith the bending properties of 3D (three-dimensional) basalt reinforced I-shaped woven composites with epoxy vinyl resin. T he 3D I-shaped woven fabrics with three different heights were fabricated on ordinary loom by reasonable design with low cost. The 3D I-shaped woven composites were fabricated by VARTM （ vacuum assisted resin transfer molding ） process. T he bending tests were conducted on a microcomputer control universal testing machine (TH-8102S). The Load-displacement and   energy-displacement   scatter plots were obtained from experimental test s . The result showed that the polynomial fitting formula can be obtained by the calculation of least square method in the software of origin   8.0.  Through the analysis of the mathematical equation and correlation coefficient of load-displacement and energy-displacement relationship,  it could be seen that the fitting effect of the curve was better.  T his mathematical  equation of this method  can be used to predict the relationship between load, energy and displacement.
