“…Four failure modes were considered from the Hashin failure criterion: fiber tensile (FT) failure, fiber compression (FC) failure, matrix tensile (MT) failure, and matrix compression (MC) failure. [29][30][31] Once any one of the failure modes was satisfied, the stiffness matrix began to degrade in accordance with the element weakening method [29][30][31] :…”

A finite element model (FEM) using a more realistic three-dimensional geometry of lattice truss core was proposed to simulate the flatwise compression test on lattice truss core sandwich composites (LTCSCs). The goal was to reduce the disparity between experimental results and FEM predictions without inclusion of imperfection, as oppose to similar studies. Besides, two modified Kagome topologies were suggested and fabricated by adding vertical composite struts at specific locations. Based on the experimental results, the modified Kagome topologies exhibited superior specific compressive stiffness and strength over the Kagome topology, by about 100%. In addition, facesheet rotation of Kagome topology was found by the FEM, which considerably affect its compressive performance. Facesheet rotation is caused by the arrangement of composite struts of LTCSC. Compressive response of LTCSC was acceptably predicted by the FEM, though there was quite high error for compressive stiffness and strength. Probable sources of discrepancy between experimental and FEM results were discussed.

This paper presents the influence of the type and structure of reinforcement, on the epoxy resin matrix polymer composites mechanical and ballistic properties. Aramid, basalt, glass fabrics and their hybrid systems were used as reinforcement. Impact strength according to Izod and "falling arrowhead", flexural strength and structure of the obtained composites were tested. The specific gravity was also determined. The aramid-glass hybrid composites showed high flexural strength (397 MPa) and Young's modulus (21 GPa). However, aramid-basalt composites had high impact strength (116 kJ/m2) and impact energy absorption (45 J).

“…14 However, a mesoscale model [15][16][17][18] is usually the smallest weaving unit capable in representing the macroscopic scale. The architectures including orthogonal weaving, [19][20][21] twill weaving, 22 and net weaving, 23 et al It also contains information of lower scale, such as yarn type, size, profile, and weaving path (Figure 2). Computational architectures of mesoscale are usually characterized by representative unit cell (RUC).…”

An orthogonal mixture woven composites with aramid yarns and carbon yarns are investigated in this work. A dual-scale computational homogenization algorithm is also proposed to address the cross-scale numerical problems. Models and methods for mesoscale and macroscale are illustrated separately. Two types of meso-structures are selected for comparison, which are termed as representative unit cell (RUC) and equivalent cross-ply laminate (ECPL), and the corresponding macro-structures are referred to as RUCs and equivalent cross-ply laminate plain-woven composites (ECPL-PWC). The key finds clarified that the ECPL-PWC takes more computational expenses compared with the RUCs, but the RUCs is in acceptable agreement with testing results, as well as the evaluation results of the ECPL-PWC would obtain very satisfactory accuracy through minor numerical adjustments. The final finite element damage results reveals that the RUCs is more accurate for local damage assessment, while the ECPL-PWC is better for global damage analysis.
