Even though several works are available on the analysis of low-velocity impact (LVI) on fibre metal laminates (FMLs), there is still scope for a better understanding of the complexities associated with their analysis, making it an important area of research. Therefore, it is essential to compile and present the state-of-the-art research in this area to make the critical information available in one paper, facilitating future research. This paper thus covers the detailed review of the articles published on the LVI response of fibre metal laminates (FMLs) based on experimental, numerical and analytical approaches and the associated damage mechanisms under different impact conditions. The discussions can be mainly categorized into two broad groups, namely geometrical and material-based parameters, which significantly influence the structural response of FMLs upon impact. Additionally, the paper compares various numerical techniques reported to model the impact behaviour of FMLs, along with an overview of analytical models. Based on the manufacturing techniques and material constituents of FMLs, the paper discusses feasible methods of improving the performance of impact-prone structures. The exhaustive review of the literature finally concludes that there are scopes of investigating some of the important and relevant areas related to LVI of FMLs like the influence of relative mass of impactor and target and accurate determination of contact stiffness for accurate estimation of interface delamination. Investigating the LVI performance of advanced sandwich structures with FML facesheets is a potential area of research in this direction.

“…This makes composite laminates more susceptible to delamination due to out-of-plane loads. 2 Composite structures are subjected to impact load during their application under various conditions. 3 For example, colliding an external object (e.g., hail or debris) with the airplane’s fuselage or the clash of tools during the repair and maintenance process is widespread.…”

Polymer matrix composites are vulnerable to low-velocity impact, although they have found many applications in high-tech industries. The main objective of this study is to improve compression after impact strength of the carbon/epoxy composites using nanoclay particles. All test samples were fabricated using a vacuum infusion process. The solution blending methodology was applied for better dispersion of the nanoparticles in the resin. The low-velocity impact response of the composite and nanocomposite laminates was investigated at various energy levels of 10, 15, and 20 J. To quantify the impact effect, the residual strength of the impacted specimens was experimentally measured under the compression test. In addition, the effect of nanoclay incorporation through the solution blending methodology on damage mechanisms was determined by the radiographic analyses and optical microscope method. The findings of this research showed a rise, up to 25.15% in the residual compressive strength, and a 7-fold increase in local buckling threshold stress of the carbon/epoxy/nanoclay specimens.

“…[1][2][3][4] The flexibility of design is the key reason for their suitability in such versatile applications, hence the design of textile structure and type of polymer resin decides the end applications. [5][6][7][8][9] In textile-based composites, normally woven structures were used as reinforcement due to better structural stability and compactness. Woven structures are further divided into two types, that is, 2D woven and 3D woven.…”

Impact of auxeticity on mechanical properties of3Dwoven auxetic reinforced thermoplastic composites

et al. 2022

3D woven composites are currently used in high-tech applications due to their better mechanical properties than 2D laminated composites. To further enhance the mechanical performance of 3D woven composites, auxetic structures can be used as reinforcement. The auxetic structures showed better mechanical properties due to bidimensional energy dissipation capability. Orthogonal 3D woven structures showed inherent auxetic nature, however, the use of brittle thermoset resins in composites fully limits their auxeticity. To overcome this issue, three types of 3D woven auxetic structures (warp, weft, and bidirectional interlocks) were developed and used as reinforcement with thermoplastic resins (PC and PVB). Auxeticity of woven reinforcement, and tensile, flexural (3-point), and short beam shear (SBS) tests of composites were conducted. Auxeticity results revealed that the warp interlock structure showed the highest auxeticity, while the bidirectional interlock structure exhibited the least auxeticity due to the high number of intersections and crimp %. Furthermore, warp interlock composite structure showed 47%, 49.5%, and 37% higher tensile, flexural, and shear strength values, respectively than bidirectional interlock structure in warp direction with PC resin. The overall results showed that auxetic reinforcement improved the mechanical performance of 3D woven composites.
