Experimental and numerical investigation of mechanical and erosion behavior of barium sulphate filled glass fiber reinforced polymer composites

Abstract

This research work evaluates the effect of barium sulphate contents on the physical, mechanical, dynamic mechanical, and erosion wear properties of fixed glass fiber reinforced epoxy composites. Composites with 0 to 30 wt% barium sulphate were prepared by vacuum assisted resin transfer molding (VARTM) technique under controlled pressure condition. The manufactured composites were characterized for physical (density, void content, and hardness), mechanical (tensile, flexural, and inter‐laminar shear strengths), dynamic mechanical, and erosion wear properties including numerical and experimental analysis. Experimental results show that the addition of increased barium sulphate content results in increased density, void content, hardness, interlaminar shear strength, and fracture toughness of the composites, while tensile and flexural properties were found to decrease above 10 wt% barium sulphate content. Erosion results revealed that the maximum wear rate was found between the ranges of 45° to 75° impingement angle, which shows semi‐ductile nature of the composites. Moreover, computational fluid dynamic (CFD simulation by ANSYS fluent) analysis was introduced to calculate the erosive wear rate, erosion scar, and then tracking the particle trajectories in order to validate the numerical results by comparing the obtained experimental results for validation. Finally, the erosion efficiency was calculated as a function of impact velocity of the proposed particulate filled composites and eroded samples were analyzed through scanning electron microscope to observe the wear characteristics of the composites.

Synergistic effect of ZnO and TiO2 nanoparticles on the thermal stability and mechanical properties of glass fiber‐reinforced LY556 epoxy composites

“…[25] Analysis of Supplementary Figure S1 indicates that the density of the ZTEG composite increases with increase in the wt% addition of the selected NPs. The densities of ZnO and TiO 2 NPs are 5.61 and 4.23 g/cm 3 , respectively, while the density of the LY556 resin is 1.1 g/cm 3 and glass fibers have a density of 2.6 g/cm 3 . Thus, during the fabrication of ZTEG composites, as the loading of such denser NPs is increased from 1 to 5 wt%, there is also a simultaneous proportionate reduction in the wt% of the matrix resin.…”

“…[1,2] Despite their great attributes, the relatively inferior interlaminar properties of GFRP composites have pushed them a way backward. Efforts are being made to improve the reliability and durability of GFRP composites via inclusion of different nanofillers into the matrix resin [3,4] or through surface modifications of glass fibers with nanoparticles (NPs). [5,6] The addition of nanofillers into the GFRP composites is one of the probable solutions to improve the interface/interphase strength of the composites.…”

Comparative Analysis of Erosive Wear Behaviour of Epoxy, Polyester and Vinyl Esters Based Thermosetting Polymer Composites for Human Prosthetic Applications Using Taguchi Design

“…Diversifying the process parameters and input variables such as matrix type, filling material, and manufacturing method can reduce the erosive wear of the manufactured composites. Calcium carbonate (CaCO 3 ), barium sulphate (BaSO 4 ), and tungsten carbide (WC) filled glass fiber reinforced PA/ABS composite prepared by injection molding exhibited relatively lower erosive wear at higher impingement angle, i.e., 90° or 75° [ 40 , 41 , 42 ]. However, the incorporation of CaCO 3 and BaSO 4 promoted ductile and semi ductile erosive wear while WC promoted brittle wear of the composite.…”

Dolomite dust filled glass fiber reinforced epoxy composite: Influence of fabrication techniques on physicomechanical and erosion wear properties

“…Authors claimed that the hardness and impact energy increased while tensile strength and tensile modulus decreased with the addition of Al 2 O 3 particles in fiber-reinforced polyester composites. The impact of barium sulphate on dynamic mechanical, erosion wear, and physicomechanical properties of glass fiber reinforced epoxy composites was investigated by Choudhary et al [18] Authors claimed that the evaluated properties such as void content, density, interlaminar shear strength, hardness, storage modulus, and fracture toughness increases while erosion wear rate decreases with barium sulphate content. Nayak et al [19] investigated the effect of nanofillers such as Al 2 O 3 and TiO 2 on the thermo-mechanical properties of glass fiber reinforced polymer composites.…”

“…Despite this, this technology has certain disadvantages, such as labour intensiveness and low volume outputs, which were resolved by the resin infusion process. [18,34] It is the widely preferred technique for the making of wind turbine blades, particularly longer blades. Few researchers have also reported the effect of dolomite filler in glass fiber composite on the mechanical and tribological properties.…”
