An experimental investigation on dynamic and mechanical characterization of olive pomace-filled glass/epoxy composite laminates

Abstract

The waste of olive pomace (OP) particle filler was incorporated with glass fiber-reinforced composites (GFRP)/epoxy resin to manufacture OP particles-modified GFRP composites. Different weight ratios (0.5, 1, 2, 5, 10, and 15 wt%) of OP particles were incorporated within the common matrix of epoxy resin to investigate the effects of OP particles on tensile, flexural, and vibration damping properties on GFRP composites. In the mechanical tests, addition of OP filler contributed the significantly enhancement in tensile and flexural modulus, and samples at 5 wt% of OP filler showed highest flexural and tensile strength, while further addition of OP filler resulted in reduction of maximum elongation value at breaking point. In dynamic tests, it was found that damping ratios of the OP particles included samples were improved by 70% at OP content of 10 wt%, while first-mode natural frequency was reached optimum value at 5 wt% of OP particles, indicating better chemical compatibility at this weight content, and further incorporation of OP particles into the epoxy resin resulted in reduction for both of mechanical and dynamic properties as a result of particle aggregation effects between OP particles-epoxy resin-fiber interfaces.

Olive Stones as Filler for Polymer-Based Composites: A Review

“…Erkliğ et al [ 65 ] studied the incorporation of olive pomace (OP) in composites reinforced with glass fiber and an epoxy resin ( Figure 12 ). Different weight ratios (0.5, 1, 2, 5, 10, and 15 wt.%) of OP particles were incorporated into the epoxy resin to investigate their effects on the tensile, flexural and damping properties of glass fiber reinforced polymer (GFRP) composites.…”

“…[5,6] In recent years, many efforts have been performed to benefit from advantages of cellulose-based fillers such as olive pomace (OP), pineapple leaf, coconut shell and palm kernel shell incorporating in polymer matrix composites for high mechanical performance and low cost composites. [7][8][9][10] In general, fiber reinforced polymer matrix composites have been modified by incorporating micro or nanosized fillers with varying shape, volume fraction and adhesion properties, and their failure characteristics have been significantly influenced due to the material discontinuities at the particle-matrix interface. [11][12][13][14][15] Later on, researchers in last decade developed various approaches to utilize olive oil residue (OP filler) in polymer matrix composites with promising bio-composites.…”
