“…When laminates are bent hard for a long time, they lose their remaining tensile strength, which lets fibers break and go through below the point of contact. In the last stages of a projectile's impact, when the fiber failure exceeds the threshold value, the laminate is completely perforated 17,31 . Furthermore, it is worth noting that the increased damage resistance of nano composite samples was predominantly due to the beneficial contribution of HNC in the form of extra microscale toughness mechanisms that improved fiber‐matrix interface performance 32 …”

The objective of this study is to produce bidirectional woven carbon/glass fiber reinforced epoxy hybrid composites and to assess their fracture toughness (FT) and low‐velocity impact strength. The composites were produced for the study by changing the stacking order of fiber layers using a vacuum assisted resin infusion process. In addition, the consequence of halloysite nano‐clay addition on the above properties were explored. The outcomes disclosed that the arrangement of fiber layer notably influences the FT and low‐velocity impact strength of the composites. Particularly, the addition of more carbon fiber layers played a key role in enhancing the FT of hybrid composites, while a reverse trend was observed for low‐velocity impact strength of composites due to the elastic nature of glass fibers, which absorbs more energy through global deformation. Additionally, the incorporation of halloysites enhanced the FT and impact strength of hybrid composites due to increased interfacial adhesion between composite elements. In addition, morphological analysis was conducted to evaluate the damage morphologies and failure mechanisms of tested laminates, which offers crucial information for the structural design of these laminates as well as for the enhancement of their performance.Highlights Fracture toughness and impact strength of hybrid composites were investigated. Arranging carbon fibers on the extreme layers enhanced the fracture toughness. Glass fiber used in hybrid composite supports to increase their impact strength. Addition of halloysite improved the overall performance of hybrid composites.

“…The impact behavior of composites under impact can differ according to the matrix type and reinforcement used [31]. Studies in the field of composites reinforced with carbon, polyethylene, and aramid woven fabrics have been reported by many researchers [32][33][34]. However, publications related to the resistance of natural fiber-reinforced composites against high-velocity impact were introduced in 2007 by Wambua et al [35].…”

In this study, the comparison of the behavior of hemp/elastomeric biocomposites based on lignin and carbon black has been investigated experimentally and numerically under the influence of high speed. SEM images confirmed the dispersion and good interaction of lignin in natural rubber with a uniform surface coverage of fibers and the gap of yarns. The results of tensile and dynamic compression tests showed that elastomer with lignin filler improves tensile strength for rubber samples and composites compared to carbon black. The high-velocity impact tests were performed on single-layer and three-layer composites based on lignin and carbon. The penetration resistance and failure mechanism of the composites during impact were validated using a constitutive material model for hemp fabric and a user-defined material model (VUMAT) for the nonlinear behavior of rubber materials with a damage criterion in ABAQUS/Explicit. For one-layer and three-layer flexible composites based on lignin, the ballistic limit is 49 and 96 m/s, respectively. Compared to carbon-based composites, it has increased by 11.36 and 13% for one-layer and three-layers, respectively. Using a thin matrix to cover hemp fabric increases the resistance of this type of fabric against high-speed impact. Through tensile failure, the stress is transferred to the surrounding fiber bundles so that more threads can participate in the load-bearing process. As a result, the penetration depth in lignin-based composites is lower, and the protective margin is greater, which increases energy absorption.

“…For carbon/aramid hybrid fiber composite laminates, the impact resistance can be improved by designing a hybrid structure of carbon fibers and aramid fibers that complement each other. 22 Hazell and Appleby-Thomas 23 improved the ballistic penetration performance of laminates by mixing aramid fabrics and aluminum plates into carbon fiber-reinforced composite materials, and found that introducing aramid fabrics on the back face was the most effective way to dissipate the kinetic energy of the projectile. Sun et al 24 found that using high-stiffness carbon fiber-reinforced composite materials in high-stress areas could effectively improve the impact resistance of carbon/aramid hybrid woven composite materials under low-speed impact.…”

This study investigated the high‐velocity impact behavior of composite plates with different hybrid ratios and structural configurations through experimental and numerical simulation studies. The results showed that the critical penetration velocity of the composite plate generally increases with an increase in the volume fraction of aramid fibers. The high‐velocity impact finite element model developed in this study accurately simulated the high‐velocity impact behavior of laminated fiber composite plates with various hybrid ratios and different structures. The impact failure patterns of the plates were analyzed, and it was observed that the carbon fibers on the back face were prone to tensile fracture, followed by the gradual fracture of aramid fibers. The numerical simulation results show significant differences in residual impact velocity and energy absorption when impacted from different sides and the impact from the aramid side resulted in better energy absorption, which is contrary to the findings in many existing research papers. These findings provide valuable insights into the impact resistance of composite materials and can guide the design and development of high‐performance composite structures for aero‐engine case designing.Highlights The high‐velocity impact behavior of C/K fiber epoxy resin matrix composite laminates are studied. The critical penetration velocity increases with the increase of aramid fiber volume fraction. The laminate absorbs most of the impact energy during the instantaneous impact time. Energy absorption ability is better when the impact surface is aramid fibers. Carbon fibers on the back side of the laminate are more prone to tensile fracture.
