摘要：
In order to solve the delamination of I-shaped laminated composites under bending loads, three I-shaped three-dimensional (3-D) woven fabrics with different heights were prepared by rational design of conventional weaving process on the common loom, then I-shaped 3-D woven fabrics with three different heights were fabricated into I-shaped 3-D woven composites by vacuum assisted resin transfer moulding technology to study the mechanical characteristics of the composites. Bending experiment and ABAQUS finite element simulation were used to compare and analyze the relationship between load/energy and displacement and the bending failure mode of I-shaped 3-D woven composites with three different heights under the same loading speed, respectively. The results show that the experimental data are in good agreement with the finite element model, showing that the finite element model has high reliability and can be used to predict the mechanical properties of I-shaped 3-D woven composites with different heights, which can provide theoretical guidance for the optimization design of I-shaped 3-D woven composites with high impact damage tolerance.
