Multi-scale finite element analysis of 2.5D woven fabric composites under on-axis and off-axis tension

“…Also, the failure of the open hole tension specimens was simulated. Lu et al [9] studied the stress-strain and progressive failure behaviors of 2.5D woven composites subjected to the axial tensile loading by using a two-step multi-scale method. Recently, Dai et al [10] presented a detailed mosaic macro model to predict the elastic and damage progressive process of 3D woven composites.…”

A study is conducted with the aim of developing voxel-based finite element method related to the whole fiber distribution for predicting the macro-mechanical properties of 3D orthogonal woven composites. For the rationality of this model, multi-scale finite element method, which is on the basis of the surface and interior representative volume cells, and digital image correlation tests are carried out. The results show that the proposed voxel-based finite element method is capable of precisely calculating the macro-level properties of 3D orthogonal woven composites, validated by the comparison the mechanical behaviors as well as the full-field strain fields.

“…However, research on 2.5D woven PMC is very limited [6][7][8]. It mainly focuses on developing the numerical tools and methodologies for analysing general 3D textile composites by taking advantage of the simpler architectures of 2.5D woven textiles.…”

Abstract. By using a gas gun apparatus, three types of 2.5D woven composites and one type of laminated composite under ballistic impact loadings were tested under ballistic impact loadings. The trajectory of the projectile was recorded by high speed camera and then analyzed to obtain the impact and residual velocities. The analysis of the experimental data suggests that the GF-2 composite has the highest impact resistance, followed by GF-1, CF-IM7 and QI-IM7. However, if the difference in density is considered, the three types of 2.5D woven composites have similar efficiency in resisting penetration. The failure and damage modes of the tested plate were visually observed.
