“…They found that interply hybrid composite exhibited higher ductile indices (8%-220%), lower peak load (5%-45%), and higher specific energy absorption (9%-67%) than those of intraply hybrid composite. Wang et al [31] studied the lowvelocity impact response of 3D woven carbon/heterocyclic aramid fiber hybrid composites. A 3D layer-to-layer interlock woven structure was used to develop four types of woven configurations, such as pure carbon fiber, heterocyclic aramid fiber as binder yarn, interlaminar hybrid, and intralaminar hybrid.…”

Three-dimensional (3D) woven textile-reinforced composites have drawn much attention because of their specific geometries, improved composite interlayer strength, and impact-resistance performance. In this study, three types of 3D woven structures with different binder-yarn ratios and paths were designed based on a traditional dobby-weaving loom with a special weft-interlock structural design. Carbon/aramid fiber-reinforced plastic (CAFRP) composites with carbon warp, weft, and aramid binder yarns, as well as carbon fiber-reinforced plastic (CFRP) composites were reinforced using the three types of woven structures and consolidated with epoxy resin. The quasi-static and dynamic flexural performance of these 3D woven composites were experimentally investigated using a three-point bending test and a low-velocity drop-weight impact test. Nondestructive ultrasonic C-scan and X-ray microcomputed tomography were applied to characterize the failure mode of the impacted composites. Woven structure and aramid binder yarn with a coarse count have a coupling effect on the quasi-static flexural performance of the 3D woven CAFRP composites. A larger volume combined with a smaller throughthickness waviness degree of aramid binder yarn has a similar effect with a smaller volume combined with a larger waviness degree. Introducing aramid binder yarn in the hybrid composites lowered the quasi-static flexural performance to a certain extent (0.28%-47.74% and 5.29%-49.63% for flexural modulus and strength, respectively) but increased the impact performance significantly (e.g., increasing 23.6%-92.7% peak-load values under 6-J impacts).A larger volume combined with a smaller waviness degree of the aramid binder yarn introduced in these woven structures contributed more to impactresistance and damage-tolerance performance.

“…The lowvelocity impact is also called large mass impact, and the impact velocity usually ranges from 1-10 m s −1 in the low-velocity impacts [20,21]. The drop-weight impact tests are widely used to assess the low-velocity impact damage behaviors of metals [22,23], composites [24,25] and metal composite laminate structures [26,27]. Andréa et al [28] explored the impact resistance of AA2024-T3 alloy and carbon fiber reinforced polyphenylene (CFRP) sulfide joints using the low-velocity drop-weight impact tests at impact energies of 2 J to 8 J, and found that 6.5 J is the critical absorbed impact energy of the joints.…”

The low-velocity impact behaviors of DP590/AA6061 self-piercing riveting (SPR) joints are studied at the impact energies of 5 J, 10 J, 20 J, 30 J, and room temperature (25℃). The lap shear and fatigue tests, and the cross-sectional microscopies of joints are used to assess the mechanical property evolutions of the joints after low-velocity impact. The results show that the absorbed impact energies of SPR joints reach the critical value at an impact energy of 30 J, the exceeded impact energy causes crack failures in the sheets and decreases the interlocking performance of the joints. The static property and the absorbed energy of the SPR joints are reduced by 16% and 36% when the joints are impacted at 30 J, respectively. The low-velocity impacts do not change the failure forms of the joints, but significantly reduce the mechanical interlocking properties of the joints. The fatigue lives of the SPR joints are reduced due to low-velocity impact, and the impacted joints are more sensitive to cyclic loadings.

“…The strong and stiff bonding between the core material and face sheets is necessary to enable the sandwich to bear high loads [19]. Kevlar fibers can improve the impact damage tolerance of the composite materials when used together with carbon fibers [20][21][22][23][24][25]. The sandwich construction is composed of two face sheets, separated by a low-density foam core.…”

“…The sandwich construction is composed of two face sheets, separated by a low-density foam core. In hybrid fiber sandwich structures, two or more types of fibers are used in the face sheets to improve the monolithic face sheet properties [25][26][27][28]. The impact and the failure mechanism for the sandwich structure is a very complex mechanism and continues to remain an active topic under discussion by many researchers [29][30][31][32][33][34][35].…”

Sandwich composites are extensively employed in a variety of applications because their bending stiffness affords a greater advantage than composite materials. However, the aspect limiting the application of the sandwich material is its poor impact resistance. Therefore, understanding the impact properties of the sandwich structure will determine the ways in which it can be used under the conditions of impact loading. Sandwich panels with different combinations of carbon/Kevlar woven monolithic face sheets, inter-ply face sheets and intra-ply face sheets were fabricated, using the vacuum-assisted resin transfer process. Instrumented low-velocity impact tests were performed using different energy levels of 5 J, 10 J, 20 J, 30 J and 40 J on a variety of samples and the results were assessed. The damage caused by the modes of failure in the sandwich structure include fiber breakage, matrix cracking, foam cracking and debonding. In sandwich panels with thin face sheets, the maximum peak load was achieved for the inter-ply hybrid foam core sandwich panel in which Kevlar was present towards the outer surface and carbon in the inner surface of the face sheet. At an impact energy of 40 J, the maximum peak load for the inter-ply hybrid foam core sandwich panel was 31.57% higher than for the sandwich structure in which carbon is towards the outer surface and Kevlar is in the inner surface of the face sheet. The intra-ply hybrid foam core sandwich panel subjected to 40 J impact energy demonstrated a 13.17% higher maximum peak load compared to the carbon monolithic face sheet sandwich panel. The experimental measurements and numerical predictions are in close agreement.
