The effect of stacking sequence of basalt and Kevlar fibers on the Charpy impact behavior of hybrid composites and fiber metal laminates

Abstract

In this study, the effect of the arrangement of Kevlar and basalt fibers as the reinforcements on the Charpy impact behavior of hybrid epoxy composites was investigated. Also, the effect of adding metal plates (aluminum 2024-T3 and stainless steel 316L) into the basalt/ Kevlar fibers reinforced epoxy composites to fabricate fiber metal laminates under Charpy impact loads was studied. The fabricated fiber metal laminates in this research consisted of three metal plates and two groups of composite layers placed between them and were fabricated by the hand lay-up technique. Results indicated that the stacking sequence of fibers due to the hybridization effect caused a considerable improvement in the energy absorption value (99%) of hybrid composites, compared to specimens with one kind of fibers. Moreover, the effect of adding aluminum plates for the fabrication of fiber metal laminate was greater than adding steel plates. Considering the weight of composites, fiber metal laminates with aluminum and steel sheets, it was found that the average specific energy absorption value of aluminum fiber metal laminates was about 2.5 times higher than those of steel fiber metal laminates and composites.

Experimental investigation on mechanical behavior of fiber–metal laminates reinforced by hybrid carbon nanotubes and nanosilica under quasi-static pressure load

“…Multilayer fiber-metal laminates are one of the most important and newest subjects in the field of composite materials which have a wide range of applications in various industries. [1][2][3] FMLs entailing several of laminates made from the combination of different layers of metal with composite layers show higher abilities to withstand external damage. They also have high impact resistance in comparison with pure composite or metal materials.…”

Study on methods to improve the mechanical properties of aramid/epoxy composites

“…Most studies are also devoted to the analysis of hybrid composites. [14][15][16][17][18] Hybrid composites are made by combining two or more chemically different reinforcing materials in a matrix. 14 The advantage of combining reinforcement in a composite is that it provides the necessary flexibility to adapt the properties of the material to the design requirements.…”

“…For impact applications, brittle inorganic fibers are always combined with ductile organic fibers to form hybrid composites such as jute/carbon, palm/glass, aramid/basalt, kevlar/flax, etc. [16][17][18] Consequently, by combining different types of fibers along with ER modification, it is possible to create hybrid composites with better stress-strain properties.…”

Effect of Aramid Fabric Orientation Angle on the Mechanical Characteristics of Basalt-Aramid/Epoxy Hybrid Interply Composites

“…Hybridisation has an advantage of offering flexibility to tailor the material properties as per the design requirements. For impact applications, brittle inorganic fibres are always combined with the ductile organic fibres to form hybrid composites such as jute/carbon, palm/glass, aramid /basalt, Kevlar/flax etc [5][6][7] .…”
