“…The same result was discussed by the author that the increase in Fly ash to polyethylene leads to increase in Flexural strength and modulus [4]. Gummadi et al also reported that flexural modulus increases for smaller filler loadings [6]. Figure 3 shows that by increasing the filler mass percentage from 0% to 30% hardness of composite increases, as filler enhanced the surface property of composite and resist deformation by penetration, that means reinforcement of lime ash particles reduces the elasticity of polymer chains resulting to a more rigid polymer [7][8][9][10].…”

This study presents findings from an experimental investigation on the reinforcement of Lime ash particles (LAP) synthesized from coal fly ash, CaO, and CaSO4 in Low density Polyethylene (LDPE). The Lime ash particles are synthesized by reinforcing 0 to 30 weight percentages of LAP in virgin LDPE using compression moulding. The mechanical properties of composites are studied and results showed that by adding LAP in LDPE as filler the Tensile Strength and Impact Strength of the composite decreases due to poor interfacial bonding between filler particles and LDPE but Hardness and Flexural Properties increases due to improved properties of surface.

“…Instead, the modulus of elasticity of the composites increased by 10-14% (Figure 9b). Gummadi et al [19] studied the flexural behavior of PP composites with ash and showed that by adding 10% ash with small particles (53-75 µm) and showed the flexural modulus and strength can be increased by 5% and 27%, respectively, but with a decrease in elongation at break by 18%. With larger particles (76-105 µm), the elongation at break decreased by half, and the flexural modulus decreased by 5%.…”

“…Nath et al [18] demonstrated that, compared to PP, injection-molded PP composites with 20-60% fly ash with a particle size of 5-60 µm exhibited a 10-60% higher modulus of elasticity, but a linear decrease in tensile strength at 25 • C and a substantial increase in tensile and impact strength at 50-70 • C. Composites based on PP with 10% ash with 53-75 µm particle sizes showed an improvement in flexural strength by approx. 30% [19].…”

There is an ever-growing interest in recovering and recycling waste materials due to their hazardous nature to the environment and human health. Recently, especially since the beginning of the COVID-19 pandemic, disposable medical face masks have been a major source of pollution, hence the rise in studies being conducted on how to recover and recycle this waste. At the same time, fly ash, an aluminosilicate waste, is being repurposed in various studies. The general approach to recycling these materials is to process and transform them into novel composites with potential applications in various industries. This work aims to investigate the properties of composites based on silico-aluminous industrial waste (ashes) and recycled polypropylene from disposable medical face masks and to create usefulness for these materials. Polypropylene/ash composites were prepared through melt processing methods, and samples were analyzed to get a general overview of the properties of these composites. Results showed that the polypropylene recycled from face masks used together with silico-aluminous ash can be processed through industrial melt processing methods and that the addition of only 5 wt% ash with a particle size of less than 90 µm, increases the thermal stability and the stiffness of the polypropylene matrix while maintaining its mechanical strength. Further investigations are needed to find specific applications in some industrial fields.

“…Several studies have been performed to introduce this waste material as a low-cost filler by itself or in various combinations with organic or inorganic materials [4][5][6][7]. In addition to these studies, fly ash was discovered to act as a reinforcing agent in a study by Satheesh et al [8], where good interaction between the ash and the matrix was achieved, while a study by Nath et al [9] and Gummadi et al [10] pointed out that the properties of PP composites with fly ash content are dependent on the particle size of said ash. In a study performed by Kutchko and Kim [11], it is pointed out that smaller-particle-size fly ash leads to better mechanical properties as long as the particles are well dispersed in the polymer matrix.…”

A cost-effective solution to the problems that the automotive industry is facing nowadays regarding regulations on emissions and fuel efficiency is to achieve weight reduction of automobile parts. Glass fiber-reinforced polymers are regularly used to manufacture various components, and some parts may also contain thermoplastic elastomers for toughness improvement. This work aimed to investigate the effect of styrene-(ethylene-co-butylene)-styrene triblock copolymer (E) and treated fly ash (C) on the morphological, thermal, and mechanical properties of long glass fiber (G)-reinforced polypropylene (PP). Results showed that the composites obtained through melt processing methods presented similar thermal stability and improved (nano)mechanical properties compared to 25–30 wt.% G-reinforced PP composites (PP-25G/PP-30G). Specifically, the impact strength and surface hardness were greatly improved. The addition of 20 wt.% E led to a 25–39% increase in impact strength and surface elasticity, while the addition of 6.5 wt.% C led to a 16% increase in surface hardness. The composite based on 25 wt.% G, 6.5 wt.% C, and 20 wt.% E presented the best-balanced properties (8–17% increase in impact strength, 38–41% increase in axial strain, and 35% increase in surface hardness) compared with PP-30G/PP-25G. Structural and morphological analysis confirmed the presence of a strong interaction between the components that make the composites. Based on these results, the PP–G–E–C composites could be presented as a viable material for automotive applications.
