This study presents an experimental investigation on the low-velocity impact response of three-dimensional integrated woven spacer sandwich composites made of high-performance glass fiber reinforced fabric and epoxy resin. 3D integrated woven spacer sandwich composites with five different specifications were produced using a hand lay-up process and tested under low-velocity impact with energies of 5 J, 10 J, and 15 J. The results revealed that the core pile’s heights and diverse impact energies significantly affect the stiffness and energy absorption capacity. There is no significant influence of face sheet thickness on impact response. Moreover, the damage morphologies of 3D integrated woven spacer sandwich composites under different impact energies were analyzed by simple visualization of the specimen. Different damage and failure mechanisms were observed, including barely visible damage, visible damage, and clearly visible damage. Moreover, it was noticed that the damage of 3D integrated woven spacer sandwich composites samples only constraints to the impacted area and does not affect the integrity of the samples.

“…The ability of impact resistance was improved significantly than that of composite without thickened face sheets, and the strength of thickened face sheets dominated the failure. In addition, Zhu et al [ 29 ] found that the core pile height also is a vital parameter for the performance of 3D integrated woven spacer sandwich composites. The force and stiffness decreased with the increase in core pile heights, but the energy absorption capacity increased with increasing core pile heights.…”

In this study, to further improve the anti‐impact property of 3D woven spacer composites (3DWSC), three kinds of integrated 3DWSC with double‐layer cores assembled at different height combinations of 4 + 8 mm, 6 + 6 mm, and 8 + 4 mm, were designed and prepared. And the impact performances and the post‐impact lateral compressive properties of the resulting composites were investigated and compared to the single‐layer 3DWSC of the same height. The results show that among the three combinations, 3DWSC‐4 + 8 has the highest contact force value of 2454.33 N at 10 J, which is 90.60% higher than that of single‐layer 3DWSC. And the residual compressive strength of 3DWSC‐4 + 8 maintains 91.30% after 10 J energy impact, while the retention value of single‐layer 3DWSC is only 68.43%. The above results can be attributed to the fact that the addition of the middle panel in double‐layer 3DWSC is benefical to improve the capacity of the material to withstand transverse load or bending moment and to absorb more energy through its damage compared to the single‐layer 3DWSC. In addition, the SEM images showed that only resin cracks in the double‐layer 3DWSC and no fiber breakage and delamination, indicating exceptional mechanical stability of the as‐prepared double‐layer 3DWSC. This work can serve as a reference for the design and fabrication to multi‐layer 3DWSC, a promising material in the field of high‐performance composites.

3D fabric‐reinforced composites with electromagnetic interference (EMI) shielding performance are in urgent demand to deal with the electromagnetic (EM) pollution. In this work, carbon spacer fabrics/polyurethane foam (CSF/PUF) composites were prepared via in situ integration of PUF with fabrics. Their EMI shielding and frequency‐selective performances were realized via designing 3D fabric. CSF/PUF possesses two types of Fabry‐Pérot cavities that generated incident EM waves' resonances according to the quarter‐wavelength theory. The average total EMI shielding effectiveness (SET) of 3CSF/PUF was 69.6 dB in the X band. The maximum EMI SET of 3CSF/PUF was up to 83.2 dB in 9.7 GHz. The peaks of EMI SE move to the high‐frequency region with the increase of carbon spacer yarns' density. Moreover, CSF acted as a reinforcement role and significantly improved the mechanical properties of PUF. The peak stress under compression, three‐point bending and low‐velocity impact increased by 4.2‐, 5.6‐, and 4.9‐folds, respectively. CSF/PUF also exhibited good thermal insulation properties, maintaining a temperature difference of at least 19.5°C across its thickness at 60°C. The as‐prepared spacing yarn carbon fabric‐reinforced composite foams may raise an interest to explore multifunctional EMI materials via fabric structure design.
