Abstract3D woven tubular composites (3D‐WTC), known for their lightweight and high‐strength characteristics, are widely used in various energy‐absorbing components. To enhance the energy absorption capacity of 3D‐WTC, this study conducted a mechanical analysis of bamboo tube structures and proposed concentric circular nested biomimetic structures with “single tube + double ribs” and “double tubes + double ribs.” 3D woven tubular composites with bamboo‐structures (3DWTC‐Bamboo) were fabricated using the vacuum‐assisted resin transfer molding (VARTM) process. Axial compression tests were conducted using a universal testing machine to reveal and discuss the energy absorption capacity and failure modes of 3DWTC‐Bamboo. The results showed that 3DWTC‐Bamboo with a “double tube + double ribs” concentric circular nested biomimetic structures performed exceptionally, with a peak load of 28.93KN and specific energy absorption of 7.74 J·g−1. The failure mode was a hybrid of “rib folding + tube wall buckling.” Finally, finite element analysis of the stress distribution during the compression of 3DWTC‐Bamboo was conducted using ABAQUS, which validated the experimental results. In summary, this work provides a reference for structural innovation in 3D‐WTC and further expands its application in the field of energy absorption.Highlights Propose “single tube + double ribs” and “double tubes + double ribs” structures. Introducing the “rib” structures to enhance the local strength/stiffness. Test results show that 3DWTC‐Bamboo has great potential in energy absorption. The “ribs” can increase the local strength/stiffness of the tube structures.

“…Metallographic microscopes, ultrasonic scanning, and various sensors were also used for void observation and analysis. [21][22][23] However, the complexity of operation and poor visualization have become the confinement of such observation methods. As an upgrade device for traditional x-ray computed tomography (XCT), the XRM technique has become a reliable one to address the microstructure and damage evolution of composite materials due to its high resolution and easy preparation.…”

Void defect is prevalent during the composite manufacturing process and may reduce the mechanical properties of composite structures, while limited information about three‐dimensional void distribution and evolution can be found due to the difficulties in void observation. In this work, void defects at different positions were detected and analyzed using x‐ray microtomography (XRM), and the random forest algorithm was implemented for segmenting components of CFRP samples. Results showed a trend of gradual rising porosity in the axial direction, with an increase of ~250% of porosity at the outlet of resin injection compared to the one at the inlet during the composite manufacturing process. The voids mainly featured with microscale between carbon fibers, with less distribution between fiber bundles and resin‐rich zones. Void defects achieved aggregation at the middle position of manufactured laminate, which is probably related to pressure interception. In the axial direction, the proportion of large‐diameter voids gradually increased, and a large volume of connected voids appeared near the outlet. Due to the shear deformation of resin and fiber and the pressure gradient effect, most of the voids showed stripe shape. The spatial orientation of voids was predominantly along the direction of resin flow and fluctuated due to fiber curl.Highlights 3D void characteristics in CFRP were studied using the XRM technique. Void formation and the effects of fibers on void morphology were analyzed. Dynamic void transport mechanisms during CFRP manufacturing were studied. Location and morphology of voids are helpful for CFRP damage modeling. The effective partitioning of CFRP was achieved using a random forest algorithm.

Three-dimensional woven tubular composites (3DWTC) exhibit superior strength and stiffness in the thickness direction, exceptional structural integrity, and interlaminar shear resistance. These properties make them promising candidates for widespread application in aerospace, automotive manufacturing, fuel transport, and various other industries. In this study, three different types of 3DWTCs were fabricated by vacuum-assisted resin transfer molding (VARTM) process using basalt fiber bundles as reinforcement materials. Low-velocity impact tests were conducted with varying impact energies, and the progression of initial damage stress as well as the ultimate damage process were analyzed utilizing a high-speed camera and three-dimensional optical microscopy. The findings of the study indicate that the shallow cross-linked (SCL) structure demonstrates the greatest impact resistance, followed by the shallow-crossed curved joint (SCCL) structure, whereas the through orthogonal (TO) structure exhibits the least impact resistance.
