Influence of stainless-steel wire mesh on the mechanical behaviour in a glass-fibre-reinforced epoxy composite

Abstract

This work covers the fabrication and investigation of the mechanical behaviour of a glass-fibre-reinforced polymer (GFRP) composite embedded with a stainless-steel wire mesh (SSWM) layer. This work takes the hybridising approach in improving the mechanical properties of GFRP through the incorporation of SSWM into the laminates. The structure of the composite is such that the SSWM was placed in the top, middle and bottom of the GFRP. The laminates are fabricated using the hand-layup method with a 40 % weight fractions of epoxy resin, 50 % weight fractions of woven glass fibre and the remainder being SSWM. The mechanical characteristics of the composites are obtained using tensile, flexural, inter delamination and drop weight impact tests. In addition to that, a morphological investigation is made utilizing a scanning electron microscope (SEM). The test outcome demonstrates that the introduction of SSWM leads to far better mechanical properties than GFRP and SSWM in the middle layer has a superior strength compared to other laminates. Keywords: glass fibre reinforced polymer, stainless-steel wire mesh, mechanical tests, ultimate strength, SEM Delo obravnava izdelavo in preiskavo mehanskih lastnosti polimera, oja~anega s steklenimi vlakni (angl. GFRP) v katerem je vgrajena ploskovna`i~na mre`a iz nerjavnega jekla (angl. SSWM). To delo predstavlja hibridiziran pribli`ek za izbolj{anje mehanskih lastnosti GFRP z vgraditvijo SSWM v laminate. Kompozit je sestavljen tako, da je bila SSWM name{~ena zgoraj, v sredini in spodaj. Laminati so izdelani z ro~nim polaganjem 40 masnimi % epoksi smole, 50 masnimi % tkanine iz steklenih vlaken, ostalo pa je SSWM. Mehanske lastnosti kompozitov so dolo~ene z nateznim in z upogibnim preizkusom, z razslojevanjem in z udarno`ilavostjo. Dodatno k temu je izvedena tudi morfolo{ka preiskava s pomo~jo vrsti~nega elektronskega mikroskopa (SEM). Rezultati preizkusov ka`ejo, da vstavitev SSWM bolj izbolj{a mehanske lastnosti kot GFRP, SSWM v sredini pa izbolj{a trdnost v primerjavi z ostalimi laminati. Klju~ne besede: steklena vlakna, jeklo oja~ano s polimeri, ploskovna`i~na mre`a iz nerjavnega jekla, mehanski preizkusi, natezna trdnost, SEM

Effect of stainless-steel wire mesh embedded into fibre-reinforced polymer facings on flexural characteristics of sandwich structures

“…Polymer matrix surrounding also eliminates additional measures for corrosion protection. 43,44 Briefly, due to their reasonable cost, ease of manufacturing, high E/q ratios and preventing catastrophic failure, they are good candidates for the applications in aviation, satellites, boat and yacht building, interior and exterior parts of the vehicles (e.g. corridor base, luggage compartments), etc.…”

“…39 stacking the wire mesh stainless steel in sandwich structures has positively affected the bending rigidity of the specimens. Sakthivel and Vijayakumar 43 investigated the hybridisation effect of glass fibre/epoxy composite with stainless steel wire mesh sheets on mechanical properties in terms of tensile strength, flexural strength, inter delamination and low-velocity impact properties. It was concluded that energy absorption capacity and the cracking behaviour of the hybrid composite were enhanced and particularly the wire mesh layer embedded into the middle of the glass fibre/epoxy composite provided the best results.…”

Investigation of mechanical properties of hybrid stainless steel/acrylic and carbon fiber reinforced epoxy composite

“…9,10 Therefore, metal reinforcement elements in various forms such as film, continuous fiber, powders, and mesh have been added to the these composites to reduce their brittleness and provide ductility. [10][11][12][13][14] The mechanical properties of glass fibermetal reinforced epoxy hybrid composites have been investigated in several experimental studies. For example, McBride et al 10 experimentally investigated the hybrid composites made of unidirectional glass fabrics and steel fabrics that have different compositions, and indicated that as the number of glass fiber layers increased, the ultimate strength increased and the failure strain decreased.…”

Performance of fiber metal laminate composites embedded with AL and CU wire mesh

“…In the hybrid composite, the middle layer of wire mesh enhances the mechanical properties of the composite [25]. In the FRPC, the 45 � oriented wire mesh shows an increased stiffness, strength, and ductility [26]. The electro polished and etched layer exposed higher interface fracture toughness between the fiber and metal interface [27].…”
