“…This indicates that the PC nanocomposites are able to sustain much higher external force before being broken, and the behavior contributes to greater deflection. The increased filler content leads to higher impact force due to the particle interface react and form a tortuous fracture path [22]. The gradual decrease in load after maximum load could be associated with localized cracking, leading to gradual failure.…”

“…The impact strength increased with fibre volume fraction (Lin et al 2006;Joseph 2002;Jayaraman et al 2003;Islam et al 2009). The increase in impact strength of composites was due to the fact that the fibre was capable of absorbing energy because of the strong interfacial bonding between the fibre and the matrix.…”

Cellulose jute fibre offers a number of benefits as reinforcement for synthetic polymers since it has a high specific strength and stiffness, low hardness, relatively low density and biodegradability. To reduce moisture uptake and hence to improve the mechanical properties of the composites, bleached jute mats were incorporated as reinforcing elements in the epoxy matrix. Composites at varying volume fractions and different orientations of jute mat were fabricated by hot compression machine under specific pressures and temperatures. Tensile, flexure, impact and water absorption tests of composites were conducted. Jute mat oriented at (0 ± 45-90)° composites showed reduced strength compared to (0-90)° fibre mat composites. Impact strength and water uptake of high volume fraction jute mat reinforced composites was higher compared to that of lower volume fraction composites. Fracture surfaces of jute mat composites were analyzed under SEM. Fracture surface of (0-90)° jute mat oriented composites showed twisted fibres, while (0 ± 45-90)° jute mat oriented composites had fibre pull-out without any twisting. Overall, composites containing 52% jute mat at orientations of (0-90)° showed better properties compared to other fabricated composites.

“…Therefore, it is essential to investigate the characteristics of these composites at high strain rate loadings. To date, several workers have reported their studies on the dynamic mechanical properties of particulate reinforced polymer composites [6][7][8]. The majority of dynamic mechanical testing is performed using a drop weight tester [6], servo hydraulic machine [7] and the split Hopkinson Pressure Bar apparatus [8].…”

“…To date, several workers have reported their studies on the dynamic mechanical properties of particulate reinforced polymer composites [6][7][8]. The majority of dynamic mechanical testing is performed using a drop weight tester [6], servo hydraulic machine [7] and the split Hopkinson Pressure Bar apparatus [8]. Lin et al [6] investigated the mechanical behaviour of epoxy reinforced modified montmorillonite (cloisite 30B) and titanium dioxide nanocomposites at dynamic loadings, using the falling mass impact tester, and found prominent improvement, in terms of impact strength, by the filler weight contents.…”
