Dynamic Mechanical Analysis of Banyan/Ramie Fibers Reinforced with Nanoparticle Hybrid Polymer Composite

Abstract

Natural fibers are an increasing potential alternative to synthetic fibers in recent research, due to their unique properties and weight ratio in composite materials. In this work, the banyan mat and ramie mat are used as reinforcement phase and the epoxy polymer is used as matrix material, and granite nanoparticles are used as filler for making composite laminates. The two phases of reinforcing and matrix were taken at an equal ratio of 50% in each, and the conventional hand layup process was fabricated making five different sequences of laminates. In this analysis, the dynamical mechanical properties of this hybrid composite are identified with the erratic weight ratio of banyan mat and ramie mat fabrics. The results revealed the maximum storage modulus is 1580 MPa at 93.8°C and a loss modulus of 298 MPa at 93.8°C in sample A, 12% more storage modulus, 17% more loss modulus was obtained in sample A compared to sample B, and 29% E ′ and 27% E ″ more compared to sample E and also using storage modulus, loss modulus, damping factor are the viscoelastic behavior which can reveal the glass transition temperature of hybrid composite laminates by conducting dynamic mechanical analysis, and SEM test was used to identify the failure mode of hybrid composite.

Investigation on Heat Deflection and Thermal Conductivity of Basalt Fiber Reinforced Composites Prepared by Hand Layup Method

“…Sample A has 41% more thermal expansion than sample D; therefore, decreasing the basalt fiber ratio from 100 g to 25 g can reveal the high positive impact during the thermal expansion analyses. Comparison between samples B and C shows that 24% higher thermal expansion occurred in sample B; similar work was conducted with sisal fiber composite and the results revealed that increasing the fiber weight fraction can improve the thermal expansion and the filler loading composite laminates reduce the coefficient of linear thermal expansion of hybrid composite [24,25]. Based on the results, it can be clearly observed that the interfacial bonding between high sawdust filler loading with basalt fiber composite was improved significantly compared to basalt fiber loading and the composite laminates.…”

Exploration of Voids, Acoustic Properties and Vibration Damping Ratio of Cyperus Pangorei Rottb Fiber and Ramie Fiber Reinforced with Epoxy Resin Hybrid Composites

“…Similar behavior was observed by Kumar et al [ 31 ] for banana/polyester and sisal/polyester composites, as well as by Etaati et al [ 32 ] for hemp/PP composites. Ramie fibers, when used as a hybrid composite, enhance vibrational properties [ 33 , 34 , 35 ].…”

“…Como resultado, o módulo de armazenamento é drasticamente reduzido. Por fim, no terceiro estágio, a região borrachosa atinge um platô [18]. A Tabela 2 apresenta os principais parâmetros para o E', E", e Tan δ. O E" é uma medida da resposta viscosa do material que indica se a energia é perdida ou dissipada durante um único ciclo senoidal de deformação.…”
