“…Since the surface property of the reinforced samples increased it shows resistance to the bending stress hence having higher flexural strength as compared to virgin LDPE. 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].…”

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.

“…The 20wt % FA and 30wt% CC with higher density of (1.78 g/cm 3 ) is found to be the optimum combination. An increase of 7.27% in micro-hardness over virgin polyethylene is obtained in composites with 10 wt% FA and 40 wt% CC [4].…”

“…It is reported in the literature that CC or RHA individually provides positive effect, but in combination, they do not support each other and such behavior is observed. This may be attributed to multiple filler loading causing more fracture sites 45 . The stress-strain curves for PP and PP composites are shown in Figure 4 along with the shape and color of dog bone samples.…”

Polypropylene is used in the textile industry in the manufacturing of plastic yarns, tapes, etc., but its low tensile strength and Young's modulus limits its associated applications. Composites of polypropylene with reinforcement of CaCO3 and rice husk ash were processed by compression molding. Bimodal porosity in rice husk ash particles has shown an improved interfacial anchoring effect via capillary effect resulting in enhanced mechanical properties, whereas such an effect is not observed with CaCO3 reinforcement in polypropylene matrix. On reinforcement with 10 wt % of each of rice husk ash and CaCO3, thermal decomposition temperature of polypropylene (333.3 °C) shifted to higher value of 415.9 °C and polypropylene Young's modulus (749.5 MPa) increased to 789.5 MPa (by 5.3%), but tensile strength decreased from 23.5 to 21.2 MPa (by 2.3 MPa only). The isolated contribution of CaCO3 and rice husk ash has been delineated, and resulting interfacial strengths have been quantified using analytical models. Rice husk ash has shown a stronger interfacial anchoring and can effectively replace CaCO3 as reinforcement for achieving improved mechanical and thermal properties of polypropylene composites. © 2018 Wiley Periodicals, Inc.

“…There are many references in the literature studying the mechanical properties of plastics filled with calcium carbonate (Adeosun and Usman, 2014;Eiras and Pessan, 2009;Roussel et al, 2005). In their study, Roussel et al,(2005) say that it is possible to improve productivity in the process through the use of calcium carbonate because of its thermal conductivity, specific heat and thermal expansion characteristics.…”

The use of functional fillers can be advantageous in terms of cost reduction and improved properties in plastics. There are many types of fillers used in industry, organic and inorganic, with a wide application area. As a response to the growing concerns about environmental damage that plastics cause, recently fillers have started to be considered as a way to reduce it by decreasing the need for petrochemical resources. Life cycle assessment (LCA) is identified as a proper tool to evaluate potential environmental impacts of products or systems. Therefore, in this study, the literature regarding LCA of plastics with functional fillers was reviewed in order to see if the use of fillers in plastics could be environmentally helpful. It was interesting to find out that environmental impacts of functional fillers in plastics had not been studied too often, especially in the case of inorganic fillers. Therefore, a gap in the literature was identified for the future works. Results of the study showed that, although there were not many and some differences exist among the LCA studies, the use of fillers in plastics industry may help to reduce environmental emissions. In addition, how LCA methodology was applied to these materials was also investigated.
