“…For sample O1 with smaller braiding angle, the curve linear elastic feature up to failure and immediately declines after attaining the peak stress, then the material is compacted and the curve rises directly. This is consistent with the previous literature . The reason is that the axial and the sixth directional yarns perpendicular to the compression direction both are subjected to the compression normal stress, and the braiding yarns are under the coupling of compression normal and shear stress, so the fibers are main bearing objects due to the cross‐network structure of material.…”

“…On the other hand, the bond force between the fibers and resin are strengthening, so the out‐of‐plane compression properties improve with increasing the braiding angle. Comparing with 3D four‐directional braided composite, for 22.72°and 34.05° braiding angle, the compression strength increase 23.2% and 49.3%, respectively . Comparing with 3D five‐directional braided composite, for 22.72° and 34.05° braiding angle, the compression strength increase 14.7% and 26.9%, respectively .…”

“…Poitrimolt et al characterized the transverse compression properties of composites by spherical indentation method. The compressive properties and failure mechanism of 3D four‐directional braided composites at room and liquid nitrogen temperatures under different loading modes were researched by Li et al They concluded that compressive properties at liquid nitrogen temperature are improved significantly. Gideon et al tested the quasi‐static axial compression behavior of 3D braided carbon/epoxy composite tube with different braiding angles.…”

Three‐dimensional (3D) six‐directional braided carbon/epoxy composites with different braiding angles were fabricated successfully. The effect of braiding angles and temperature on mechanical properties and failure mechanism were analyzed. The results show that the braiding angle and temperature both have a significant effect. As braiding angle increases, out‐of‐plane compression stress vs strain curve increases and the compression properties improve. At high temperatures, the stress vs strain curves are non‐linear up and the compression properties reduce. Besides, the out‐of‐plane performances of 3D six‐directional braided composite at room and high temperatures are more excellent than 3D four‐directional and five‐directional braided composites. Under out‐of‐plane compression, at room temperature, the materials appear 45° shear fracture; the phenomenon of fibers shear fracture and extraction is more distinct with larger braiding angle; the main failure is the fiber bundles expand outward and the matrix cracks. At high temperatures, the materials exhibit ±45° shear cracks; composites are compressed flat and expand along the transverse direction; the main failure is the matrix softening and exfoliation from the fiber bundles, the fiber/matrix interface debonds seriously.

“…The influences of temperature on compressive behaviors of 3D braided composites have been investigated at high and low temperature in experimental [1][2][3][4][5]. In numerical, representative volume cell (RVC) method [6,7], multi-unit cell model (MUCM) [8][9][10] and multi-scale structure model [11] were often employed to predict mechanical behaviors of 3D braided composites.…”

This paper reports a numerical modeling on the compressive behaviors of 3-D braided carbon / epoxy composites with different braided angles under high temperatures at microstructure level. The coupling effect of temperature and braided angle on the compressive failure mechanisms and damage morphologies have been calculated with finite element method (FEM) and compared with experimental results. In the FEM model, the imperfect interfacial bonding and the fibers with waviness were introduced into the FEM model. The ductile/brittle transition temperature was investigated and the ductile failure criterion was employed in the FEM model at high temperatures. It was found that braided angle affects the compressive failure. The compressive failure changes from ductile to brittle when the braided angle changes from larger to smaller one. The high temperature has almost no influence on the damage mode but it leads to the failure modes more ductile. The thermal stress improves the longitudinal compressive properties. The higher temperature and larger braided angle lead to the ductile behaviors of the 3D braided under longitudinal compression.Keywords: 3D braided composite; high temperature; ductile/brittle transition; failure mechanism; finite element method (FEM).

Li et al [13] preformed compressive experiments on the 3D braided composites with different braiding parameters in three directions (longitudinal, in-plane and transverse) at room and liquid nitrogen temperature (low as À196°C). Li et al [14] characterization of the effect of cut-edge on the tensile, compressive and flexure properties in the braiding direction of the 3D braided composites.…”
