“…In this test also, the composite B2C0J8 was achieved a maximum impact strength of 82.4 kJ/m 2 , and it indicates that this composite absorbs more energy before the failure of the composite. [73][74][75] Also, the more amount of jute fibers reinforcement has an advantage in terms of energy absorption. The least impact strength was achieved by the B2C8J Composite, and the value is 52.04 kJ/m 2 .…”

In this current research study, nine different combinations of coir, jute, and bamboo reinforced epoxy composites were fabricated using casting technique. These composites were employed to mechanical tests such as flexural and impact tests, and analyzed the thermal stability through Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC). Moreover, the thermal conductivity and surface morphology was also studied for hybrid composites. The hybridization of more than one fiber with epoxy matrix resulted in better mechanical and thermal properties as compared to individual reinforcements, and this statement is agreed with the present research work as well as the research works reported in the literature. The hybrid composite with the maximum amount of jute fibers reinforcement with bamboo fiber (B2C0J8) exhibited maximum flexural and impact strengths of 92.521 MPa and 82.4 kJ/m 2 respectively, which is due to the higher modulus and energy-absorbing behavior of jute fibers, also it was an advantage of coir fibers absence having lower modulus and strength values. In thermal conductivity analysis, the marginal variations of values were observed with different volume fractions of fibers, and the maximum conductivity (0.317 W/m-K) was obtained for B2C8J Composite having only coir and bamboo fiber reinforcements with epoxy matrix. The Thermogravimetric analysis results reveal that all nine types of hybrid composites possess nearly equal thermal stability, and slight variations in degradation temperatures were observed in the thermographs. The B2C1J7 hybrid composite was recommended for better mechanical and thermal properties, where it has 89.06 MPa of flexural strength, 78.6 kJ/m 2 of impact strength, 0.233 W/m-K of thermal conductivity and exhibited better surface morphology.

In the current work, the influence of calcium carbonate (CaCO 3 ) filler loadings on the physical, mechanical, thermal, and morphological properties of pine fiber (PF) reinforced polyester composites were analyzed. The fillers loaded PF/polyester composites were fabricated using casting technique. The results revealed that the volume percentage voids in the filler-loaded composites was less as compared to neat PF/polyester composites due to filler occupancy in the air gaps of fabricated composites. The tensile strength increment in neat PF reinforced composites (10-30 vol%) was prompted by the polyester's ability to wet PF per-

“…The composite failure during tensile testing is dependent upon crack initiation and propagation of the crack inside the composites. [60,61] The tensile strengths of jute fiber reinforced coir/bamboo hybrid composites with various fiber loadings are shown in Figure 1. The maximum and superior tensile strength obtained was 129.3 MPa for the composite JC8, and the least value of tensile strength was recorded for the composite JC7 at 56.6 MPa.…”

Environment protection is the current theme for many industries by utilizing biodegradable natural fibers for products development. The growing awareness of the environmental harm caused by synthetic materials has resulted in the emergence of eco-friendly materials. This work aims to fabrication of jute, bamboo, and coir fiber reinforced hybrid composites (12 combinations) with the analysis of mechanical, thermal, and morphological properties. The tensile and flexural tests reveal that the composite JC8 (21% jute, 1.5% coir, 7.5% bamboo) exhibited maximum tensile and flexural strengths of 129.3 and 98 MPa respectively due to higher cellulose constituents in jute and bamboo fibers that resulted in higher degree cellulose polymerization with the epoxy matrix, and also the capability of tension and bending resistance. The combined effect of hybrid fibers stiffness and strong interfacial adhesion were also the reason for maximum flexural strength. The thermal stability of all the composites was remains the same, and considerable weight loss was observed between the ranges of 200 and 500 C. Overall, the hybrid composite JC8 has 21% jute, 1.5% coir, and 7.5% bamboo on the basis of volume percentage exhibited a maximum tensile strength, flexural strength, thermal stability and better surface morphology than other hybrid composites.
