Analysis of the Effect of Parameters on Fracture Toughness of Hemp Fiber Reinforced Hybrid Composites Using the ANOVA Method

Abstract

In today's world, global warming has become a concern. To overcome this, we need to reduce the carbon footprints caused by the production of materials. Much of the time, this is equivalent to the same amount of CO2 emissions per tonne of production. This is a serious concern and needs to be overcome by identifying alternative materials to have as minimal a carbon footprint as possible. In this context, hemp fiber is by far the best natural fiber when compared to its peers. As per the survey conducted by the Nova institute, hemp has CO2 emissions of only 360 Kg/tonne, whereas jute has CO2 emissions of 550 Kg/tonne, kenaf 420 Kg/tonne, and flax 350 Kg/tonne. This paper presents an experimental study of the fracture toughness of hemp-reinforced hybrid composites (HRHC). The effect of the parameters on the fracture toughness behavior of HRHC is studied using the Taguchi technique. It uses different filler combinations with hemp fiber and epoxy. Hemp fiber is used as the reinforcement, epoxy resin is used as a matrix, and banana fiber, coconut shell powder, and sawdust are used as fillers. The experimental plan is prepared using an orthogonal array and analyzed using Minitab software. The obtained results were analyzed using ANOVA and main effects plots. It was observed that the fracture toughness increases with a decrease in thickness. The fracture toughness is affected by the fiber content in the range of 25–35% and is also affected by the filler materials.

Optimization and mechanical characterization of casein and seaweed resin with hemp reinforcement: A review

“…Madhusudhana H.K et al [1] Using the Taguchi approach, the fracture toughness behavior of HRHC is examined as a result of the variables, such as a change in the ratio of epoxy resin and fillers like banana, sawdust, and powdered coconut shell. The current research will develop replacement materials for consumer product packaging or light-duty automotive uses.…”

“…The effect of bio‐fibers and bio‐particles on fracture toughness and fracture behavior was investigated by Gope et al 30,31 Rao and Gope 32 studied the effect of walnut particles and coconut fiber‐reinforced hybrid biocomposite on fracture toughness. The effects of hemp fiber, banana fiber, coconut shell powder, and sawdust on fracture toughness were studied by Madhusudhana et al 33 using the Taguchi method.…”

Use of Yarn and Carded Jute as Epoxy Matrix Reinforcement for the Production of Composite Materials for Application in the Wind Sector: A Preliminary Analysis for the Manufacture of Blades for Low-Intensity Winds

“…Jute fiber from the species Corchorus capsularis is characterized by its low weight and relatively good mechanical resistance and can naturally reach large diameters and lengths, making it an attractive option under this specific issue for structural applications [ 14 , 15 , 16 , 17 ]. The physical and mechanical properties of jute fiber found in the works of Tanguy et al [ 18 ], Awais et al [ 19 ], Ribeiro et al [ 20 ], Ganesan et al [ 21 ], Ahamed et al [ 22 ], and Khalid et al [ 23 ] are shown in Table 1 .…”
