“…This shows that increase in FA may lead to increase in flexural modulus while increase in CC may lead to a decrease in flexural modulus. This is in line with the work of Ahmad and Mahanwar [24] who reported that increase in FA content leads to increase in flexural modulus. Gummadi et al [3] …”

“…It is observed that flexural strength decrease initially when the combination of the filler is dominated by CC but increase sharply when the filler content is dominated by FA. It has been reported that increase in the content of fly-ash to polyethylene leads to increase in flexural strength [24]. The authors attributed this increase to the formation of fairly strong interfacial bond between the matrix and filler leading to an effective stress transfer from matrix to filler.…”

The synergetic effect of calcium carbonate (CC)-fly ash (FA) hybrid filler particles on the mechanical and physical properties of low density polyethylene (LDPE) has been investigated. Low density polyethylene is filled with varying weight percentages of FA and CC using melt casting. Composites are characterized for mechanical, thermal, microstructural and physical properties. Results show that the flexural strength increases with increases in FA content of the hybrid filler. It is evident from the study that to achieve optimum density a certain combination of both fillers need to be used. The optimum combination of CC and FA for a higher density (1.78 g/cm 3 ) is found to be at 20 wt% FA and 30 wt% CC. An increase of 7.27% in micro-hardness over virgin polyethylene is obtained in composites with 10 wt% FA and 40 wt% CC. The presence of higher amount of CC is seen to be detrimental to the crystallinity of composites. X-ray, FTIR and DSC results show that composite with 45 wt% CC and 5 wt% FA exhibits a typical triclinic polyethylene structure indicating that the composite is amorphous in nature. There was the synergy between FA and CC fillers on flexural strength and crystallinity of composite. However, the fillers show the antagonistic effect on energy at peak and micro-hardness.

“…In addition, coal has natural antifungal properties and low water absorption capacity (compared to wood). While coal combustion byproducts such as fly ash and cenospheres have been evaluated as fillers for plastic composites , only recent research efforts have begun to explore the possibility of using coal as a filler in thermoplastic and thermosetting polymers. Hu et al incorporated coal with sodium humate coupling agent into a mixture of carboxymethyl starch and polyvinyl alcohol to increase the tensile strength of thin plastic composite films to approximately 10 MPa with 60 weight percentage (wt%) coal.…”

Mechanical performance of thermoplastic composites using bituminous coal as filler: Study of a potentially sustainable end‐use application for Appalachian coal

This study evaluated the utilization of bituminous coal from the Appalachian basin as filler material in high density polyethylene (HDPE) composites. Three coal types including Pittsburgh No. 8, Kittanning, and Upper Freeport were evaluated. The impact of coal (0–60 wt%) and coupling agent (0–3 wt%) content on flexure and tensile properties of the coal/HDPE composites was investigated. In addition, coal surface chemistry was analyzed using Boehm analyses and compared to pine wood flour. Composite flexure strength was maximum at 30 wt% coal, while tensile strength decreased with coal content. Addition of coupling agent to the composite had little to negative impact on mechanical properties. POLYM. COMPOS., 40:591–599, 2019. © 2017 Society of Plastics Engineers

“…It has wide applications in structural, packaging, and other commercial products. Reinforcement of HDPE with FA particles has led to the significant improvement in different properties of HDPE, for example, Ahmad and Mahanwar studied mechanical properties of FA (containing three different particle sizes) reinforced HDPE composites and observed an increase in tensile and flexural strengths and moduli with reduction in elongation at break for particles with smallest size.

This article describes an industrially viable melt blending approach for the preparation of high‐density polyethylene (HDPE)/fly ash composites having high loading of fly ash (FA) (up to 25 wt %). In this approach, solvent was used to enhance the mixing of FA in HDPE matrix. FA coated on the outer surface of HDPE granules using solvent is an economical technique for the incorporation of high loading of FA using conventional twin screw extruder. Herein, the effect of HDPE reinforced with FA on thermal, rheological, and mechanical properties has been investigated. Incorporation of FA in HDPE matrix resulted in higher storage modulus (E′), loss modulus (E″), and complex viscosity (η*) as compared to neat polymer. Tensile and flexural moduli were also found to increase (∼47% and ∼66%, respectively) with the addition of FA (25 wt %). However, the elongation at break of HDPE reduced as the rigid spherical FA particles do not undergo elongation. The dispersion of FA within the polymer matrix and interaction of FA with HDPE were investigated using scanning electron microscopy. Rheological and mechanical properties of the composites were also correlated with the morphology. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45995.
