“…Under compression load, various failure mechanisms (e.g., fiber fracture, interfiber failure, inter and intralaminar friction, fragmentation) additionally enable an excellent energy absorption capacity. Further investigations of Callens, [4] Mosleh et al, [2] or Lehmann et al [3] report similar improvements of the bending, impact and tensile behavior as a result of steel fiber integration into CFRP and proves the beneficial mechanical performance of this fiber hybrid material. In case of applications with special requirements, for example, regarding the reliability of operation, this can cause the exclusion of CFRP as construction material.…”

The integration of ductile continuous steel fibers into thermoset carbon fiber reinforced polymer (CFRP) enables significant enhancements of its damage tolerance and crashworthiness. Due to their high strain at failure, the embedded steel fibers provide alternative load paths after failure of the brittle carbon fibers. The resulting post damage performance of the hybrid composite depends on the proportions of the different types of reinforcing fibers, their individual properties, the laminate architecture, and particularly on the steel fiber resin adhesion. So far, common constitutive laws for fiber reinforced composites have very limited suitability for the complex interrelation between the nonlinear plastic behavior of steel fibers and the elastic behavior of the carbon fibers. For this reason, a novel analytical method is developed to predict the failure performance of fiber hybrid composites. In principle, the analytical approach is based on a structural dynamic analysis of the fracture gap formation during failure and thus unloading of the brittle carbon fibers. The present paper covers the derivation of this analytical approach and its exemplary application to a steel and carbon fiber reinforced hybrid composite. A final comparison with an experimentally obtained stressstrain curve validates the theoretical model introduced.

Lack of energy dissipation is one of the shortcomings of conventional glass fiber reinforced composites. The addition of steel fibers to the conventional FRP composite to create a hybrid composite has been recently investigated as an option to address this limitation. The current literature is limited to composites reinforced with metal and non-metal fibers of the same alignment. In this study, hybrid and nonhybrid FRP composites of different layups, fiber content, and weave type were manufactured and subjected to hysteretic tensile loads. Woven glass fabrics in ±45° orientation were hybridized with unidirectional stainless steel fabrics in 0° and 90° orientations. This put the glass and steel layers in in-plane shear and normal stresses, respectively. The nonlinear stress–strain relationship, residual plastic strains, energy dissipation capability, and failure mechanisms of hybrid and nonhybrid composite type were compared. The hybrid composites presented improved energy dissipation, tensile strength, and stiffness when compared to nonhybrid ones. The applicability of an existing constitutive model that was originally developed for in-plane shear of conventional composites was investigated and refinements were proposed to present the hysteretic stress–strain relationship after addition of steel fibers. The refined model captured the increased plastic strain values and energy dissipation because of stainless steel fibers in the hybrid composite samples. An Armstrong–Frederick plasticity model was implemented to model the stress–strain relationship of the stainless steel composite samples.

“…Though FRP composites show promise for application in various industries, the brittle nature of the fibers and limited capacity for energy absorption restrict the ability of the FRP to perform in critical structural elements that need protection from extreme events. Studies have investigated ways to improve the ductility of composites, and the incorporation of metal fibers into FRP composites for this purpose has been recently studied [ 10 , 11 , 12 , 13 , 14 , 15 ]. Metal fibers have high stiffness, high strength, ductile failure, high tensile energy absorption, high electrical conductivity, and superior structural integrity following impact [ 16 ].…”

Mechanical Behavior of Stainless Steel Fiber-Reinforced Composites Exposed to Accelerated Corrosion

Recent advancements in metal fibers have introduced a promising new type of stainless steel fiber with high stiffness, high failure strain, and a thickness < 100 μm (<0.00394 in.) that can be utilized in a steel fiber-reinforced polymer. However, stainless steel is known to be susceptible to pitting corrosion. The main goal of this study is to compare the impact of corrosion on the mechanical properties of steel fiber-reinforced composites with those of conventional types of stainless steel. By providing experimental evidences, this study may promote the application of steel fiber-reinforced composite as a viable alternative to conventional metals. Samples of steel fiber-reinforced polymer and four different types of stainless steel were subjected to 144 and 288 h of corrosion in ferric chloride solution to simulate accelerated corrosion conditions. The weight losses due to corrosion were recorded. The corroded and control samples were tested under monotonic tensile loading to measure the ultimate stresses and strains. The effect of corrosion on the mechanical properties of the different materials was evaluated. The digital image correlation (DIC) technique was used to investigate the failure mechanism of the corrosion-damaged specimens. Overall, steel fiber-reinforced composites had the greatest corrosion resistance.
