“…Therefore, it was investigated with the compression properties of 3D I-shaped woven composites with three different heights and three different thicknesses in this article. At the same time in the research of mechanical properties, the 3D woven composites with other shaped 3D woven fabric researched by Lv and colleagues [12][13][14][15] also provided the basis for the 3D I-shaped woven compression property of this article.…”

In order to improve the defect of incompleteness, three-dimensional I-shaped fabrics with basalt fiber filaments tows were woven on the semi-automatic loom by reasonable design. Three-dimensional I-shaped woven composites were prepared by the vacuum-assisted resin transfer molding process. The compressive behaviors of three-dimensional I-shaped woven composites with three different heights and thicknesses were studied. Through the evaluation of load–displacement curves and total energy absorption of the three-dimensional I-shaped woven composites, the results indicated when the thickness was fixed to 2 mm, the maximum compression load with height 20 mm raised 522.72 N as against that with height 60 mm and the maximum compression load with thickness 6 mm raised 2571.81 N as against that with thickness 2 mm. Consequently, the compression properties of three-dimensional I-shaped woven composites decreased with the increasing heights of the composites, while increased with the increasing thickness of the composites. Analyzing morphological characteristics of composites after fracture and load–displacement curves of composites, it was concluded that the compression failure modes had brittle fracture of the fiber bundle, cracking of the matrix, and a typical shear failure in the beam (A2). Despite the above-mentioned failure mechanisms, the three-dimensional I-shaped woven composite still had good integrity without delamination.

The delamination resistance and damage tolerance of traditional honeycomb composites are poor. To overcome these defects, 3D (three-dimensional) integrated woven composites of honeycomb structure were designed, and then manufactured using the vacuum assisted resin transfer molding process (VARTM), based on the 3D self-prepared fabrics used as reinforcements. The load-displacement curves, maximum bending load-velocity curves, and bar chart of energy absorption were determined experimentally and calculated by finite element simulation. The results showed good agreement between experimental and finite element simulation data. The correctness of the model was verified, so the model can be used to predict the mechanical properties of 3D integrated woven composites of honeycomb structure with quadrilateral cross section.

Conventionally laminated spacer composites are extensively applied in many fields owing to their light weight. However, their impact resistance, interlaminar strength, and integrity are poor. In order to overcome these flaws, the zigzag-shaped 3D woven spacer composites were rationally designed. The zigzag-shaped 3D woven spacer fabrics with the basalt fiber filaments tows 400 tex (metric count of yarn) used as warp and weft yarns were fabricated on a common loom with low-cost processing. The zigzag-shaped 3D woven spacer composites were obtained using the VARTM (vacuum-assisted resin transfer molding) process. The three-point bending deformation and effects of damage in zigzag-shaped 3D woven spacer composites were studied both in experiment and using the finite element method (FEM). The bending properties of zigzag-shaped 3D woven spacer composites with different direction, different numbers of weaving cycle, and different heights were tested in experiments. In FEM simulation, the geometrical model was established to analyze the deformation and damage based on the 3D woven composite structure. Compared with data obtained from the experiments and FEM simulation, the results show good agreement and also prove the validity of the model. Based on the FEM results, the deformation, damage, and propagation of stress obtained from the model are very helpful in analyzing the failure mechanism of zigzag-shaped 3D woven composites. Furthermore, the results can significantly guide the fabrication process of real composite materials.
