“…Finally, comparing the estimation performance of the developed FE simplified models with the other previous FE model [ 15 , 34 , 35 , 36 ] have shown that both models have generated an acceptable level of accuracy with a relative error between 0 and 27.5%. Sing et al [ 15 ] estimated the glass fiber reinforced epoxy composite (GFREC) tensile properties using a 3D solid FE model with isotropic material definition.…”

“…The Elium ® based 3D-FRC took approximately fourfold to completely infuse the panel because low vacuum pressure was used to avoid void/bubble formation during the polymerization process. More details on the fabrication process can be found in our earlier publications [ 6 , 31 , 32 , 39 ].…”

The flexure response of novel thermoplastic (Elium®) 3D fibre-reinforced composites (FRC) was evaluated and compared with a conventional thermoset (Epolam®)-based 3D-FRC. Ten different types of sample 3D-FRC were prepared by varying fibre orientations, i.e., 0°, 30°, 45°, 60° and 90°, and resin system, i.e., thermoplastic and thermoset. The bending characteristics and failure mechanisms were determined by conducting a three-point bend test. Results elucidate that the on-axis specimens show linear response and brittle failure; in contrast, the off-axis specimens depicted highly nonlinear response and ductile failure. The thermoplastic on-axis specimen exhibited almost similar flexure strength; in comparison, the off-axis specimens show ~17% lower flexure strength compared to thermoset 3D-FRC. Thermoplastic 3D-FRC shows ~40% higher energy absorption, ~23% lower flexure modulus and ~27% higher flexure strains as compared to its thermoset counterpart.

“…During the numerical modeling, the homogenization method based on unit-cell and the full-size meso-structural model are often employed, and the constitutive model, failure criteria, and degradation model after damage initiation for component materials should be determined. Shah et al [ 30 ] proposed a multiscale progressive damage modeling methodology for 3D woven composites, which can be implemented in most finite element software to create a digital twin for simulation of damage response. Zhang et al [ 31 ] numerically investigated the impact damage behaviors of a 3D angle-interlock woven composite subjected to transverse impact at subzero temperatures.…”

Micromechanisms and Characterization of Low-Velocity Impact Damage in 3D Woven Composites

et al. 2022

Low-velocity impact (LVI) damage of 3D woven composites were experimentally and numerically investigated, considering different off-axis angles and impact energies. The impact responses were examined by LVI tests, and the damage morphology inside the composites was observed by X-ray micro-computed tomography (μ-CT). Yarn-level damage evolution was revealed by developing a hybrid finite element analysis model. The results show that the impact damage has significant directionality determined by the weft/warp orientation of the composites. The damage originates at the bottom of the impacted area and then expands outwards and upwards simultaneously, accompanied by in-plane and out-of-plane stress transfers. The straight-line distributed weft/warp yarns play an important role in bearing loads at the beginning of loading, while the w-shape distributed binder warp yarns gradually absorb impact deformation and toughen the whole structure as the loading proceeds. The effect of directional impact damage on post-impact performance was explored by performing compressing-after-impact (CAI) tests. It is revealed that the CAI properties along principal directions are more sensitive to the low-velocity impact, and the damage mode is significantly affected by the loading direction.
