Jute based green composites are emerging materials due to their certain attractive properties like appropriate strength to weight ratio, high damping ratio, low price and corrosion resistance. Jute/carbon hybrid composite can replace carbon fiber reinforced composites without much loss in tensile strength. These hybrid composites are now being used in various automobile interior and exterior parts. In this study tensile behavior of carbon/jute reinforced epoxy hybrid textile composites, for different volume fractions of carbon and jute fibers, is studied experimentally and numerically. Tensile behavior of composite materials is always required for design and analysis of any structure. It is found that with increase in jute percentage tensile strength of hybrid composite decrease. Numerical results agrees well with experimental results and error increases with increase in jute percentage due to heterogeneous jute properties and waviness of fabrics. Fractographic study reveals that delamination phenomenon exists in between plies and jute fiber shows more pullout than carbon fiber. Scanning electron microscope analysis depicted that matrix fails in form of fragmentation while fibers show pullout during failure.

“…A slight mismatch was found when experimental and numerical results were compared [26]. A numerical study for predicting the flexural strength of thick-walled carbon fiber reinforced composites (CFRP) was conducted by taking engineering constants from the tensile test of thin-walled CFRP composites [27]. The error for unidirectional composites was found to be 10%, while for woven composites, more than 10% error was encountered.…”

Natural fibers, especially jute fibers, have gained interest in recent decades due to their attractive mechanical properties, high cellulose percentage, low cost, biodegradability, and easy availability. In the present study, flexural and drop weight impact behavior for different weight percentages of glass and jute fiber reinforced epoxy composites are studied experimentally according to ASTM standards. The hybrid composites were prepared through the compression molding technique. Numerical simulations were performed to investigate the predictive flexural response. The leading cause of error between experimental and numerical results is the manufacturing process and the reinforcement's woven nature. On the other hand, the impact strength was studied through drop weight testing at fixed 10 J energy. It is found that damage area decreases with increasing jute percentage in glass/jute hybrid composites, showing that jute fiber contributes more towards the composites' impact strength than glass fiber. Therefore, jute fiber can replace glass fiber in the glass/jute hybrid composite as a natural and eco-friendly constituent. The microscopic study reveals that the outer glass fiber layer helps minimize the stress distribution of jute fiber. A significant drawback of compression molding is the epoxy affluent areas in the composite.

“…This modeling method, due to good numerical effi ciency of the model, can be used in the static analyses of structural elements made of laminates [6,7]. However, such a modeling method can cause erroneous simulation results [7,8], and simulating delamination with its help requires the use of special computational methods (e.g. VCCT [9], cohesive zone method [10]), which signifi cantly reduce the numerical effi ciency of the model and require predicting the location of potential damage sites.…”

AbstractLayer composites reinforced with fabrics – laminates are construction materials in which mechanical properties can be shaped by designing their microstructure appropriately. However, the multi-phase microstructure of laminates makes it difficult to calculate the strength of the laminate constructions, especially when the reinforcement is a fabric. The article presents a special calculation model for determining the strength of an exemplary construction element made of laminate reinforced with a roving fabric with a plain weave made of carbon fibers. The computational model reflected in a simplified way the laminate microstructure, i.e. the number and orientation of the reinforcement fabric layers and its weave, and enabled a simulation of the behavior of the construction element under load up to fracture, which occurred as a result of breaking the reinforcement and interlayer crack – delamination. The simulation results were compared with the results of experimental stand tests. A method of modifying the computational model for laminates reinforced with non-plain weave was also suggested.
