Effects of filler loading were investigated in rattan powder-filled polypropylene composites. The composites were melt-blended using a Polydrive Thermo Haake internal mixer by incorporating rattan powder into polypropylene matrix. Rattan powders used were of average size 180µm with filler loadings ranging between 0 to 40 phr. The results indicate that tensile strength and elongation at break show a decrease with increasing filler loading. Tensile modulus increased with addition of rattan powder and eventually decreased with high filler loading. This is due to higher rattan powder content has more tendency to agglomerate causing weaker interfacial adhesion between rattan filler and polypropylene matrix. The deterioration in tensile properties was confirmed by morphological studies of fractured surfaces.

Tensile properties and morphological studies of linear low density polyethylene (LLDPE)/poly (vinyl alcohol) (PVA)/kenaf (KNF) composites were investigated. The composites with different KNF loading (0, 10, 20, 30, 40 phr) were prepared using a Thermo Haake Polydrive internal mixer at 150°C and 50 rpm for 10 min. The results indicated that tensile strength and elongation at break were decreased with increasing KNF loading, whereas tensile modulus showed the opposite trend. Tensile fractured surfaces observed by scanning electron microscopy showed better interfacial adhesion between LLDPE/PVA and KNF at 10 phr KNF loading.

Unmodified talc fillers were compounded with polypropylene (PP) and copolymer polyethylene (Co-PP) separately in a Brabender plasticorder internal mixer at 180 °C and 50 rpm in order to obtain composites, which contain 040 phr (per 100 part of resin) of filler at 40 phr intervals. The morphology development and the mechanical properties of the composites with reference to filler loading were investigated. In terms of mechanical properties, Youngs modulus and maximum compression load increased, whereas yield strength and elongation at break decreased with the increase in filler loading of PP/Co-PP/Talc composites. The PP/Co-PP exhibited lower yield strength and youngs modulus, and higher elongation at break than talc composites (data not show here). Scanning electron microscopy (SEM) was used to examine the structure of the fracture surface to justify the variation of the measured mechanical properties.

Poly(butylene succinate)/Poly(hydroxybutyrate-co-hydroxyhexanoate) (PBS/PHBHH) blends were prepared using melt blending in an internal mixer at 160°C. Mechanical and morphological properties of the blends, with ratios of 10/90, 20/80, 30/70, 40/60 and 50/50, are studied by tensile test and microscopy analysis. The effects of maleated PHBHH (PHBHHgMA) compatibiliser on the blend’s mechanical and morphological properties are also investigated. The compatibiliser is prepared by melt grafting maleic anhydride (MA) onto PHBHH at 160°C, in the presence of dicumyl peroxide (DCP) initiator. In this study, the purified compatibiliser is added to the blends. The highest tensile strength was achieved by the 10/90 blend, with a value of 24.83MPa; which is slightly higher than the neat PBS. The tensile modulus of the blends decreased with increasing PBS ratio, and approximately followed the Rule of Mixtures. Meanwhile, the elongation at break achieved its optimum value at 10wt. % PBS loading. The addition of PHBHHgMA at 5wt. % improved the tensile properties of all blends; with the highest value being achieved by the 10/90 blend ratio. Morphological observation via SEM was conducted to observe phase morphology and compatibility between the blend’s components.

This work studied possibilities of using waste silicon carbide (SiC) particles from abrasive industry as alternative filler in natural rubber (NR) compounds. The rubber was prepared by using natural rubber grade STR 5L and waste silicon carbide loading of 0, 10, 20, 30 and 40 phr. Firstly, the rubber were compounded by using two roll mill and then using Oscillating Disc Rheometer for studying cure time at one hundred and fifty degree Celsius. Then, shear viscosity and extrudate swell of the compounded natural rubber were characterized by using capillary rheometer at 100°C. The result showed that the apparent shear viscosity increased slightly with increasing waste silicon carbide loading and the percentage of extrudate swell was found to be a decreasing function of the filler loading. Then, test tensile by using the prepared samples for studying tensile modulus, tensile strength and elongation at break. The result showed that tensile modulus and tensile strength increased with increasing waste silicon carbide. On the other hand, the elongation at break of the filled natural rubber decreased with increasing waste silicon carbide. Finally, bring the sample to test hardness by using shore A. Results indicated that waste silicon carbide direct variation with the indicator of hardness.

This study aims to investigate the effect of AgNPs on the mechanical, thermal and antimicrobial activity of kenaf/HDPE composites. AgNP material was prepared at different contents, from 0, 2, 4, 6, 8 to 10 wt%, by an internal mixer and hot compression at a temperature of 150 °C. Mechanical (tensile, modulus and elongation at break), thermal (TGA and DSC) and antimicrobial tests were performed to analyze behavior and inhibitory effects. The obtained results indicate that the effect of AgNP content displays improved tensile and modulus properties, as well as thermal and antimicrobial properties. The highest tensile stress is 5.07 MPa and was obtained at 10wt, TGA showed 10 wt% and had improved thermal stability and DSC showed improved stability with increased AgNP content. The findings of this study show the potential of incorporating AgNP concentrations as a secondary substitute to improve the performance in terms of mechanical, thermal and antimicrobial properties without treatment. The addition of AgNP content in polymer composite can be used as a secondary filler to improve the properties.

Abstract In this study, the morphological and mechanical performances of hybrid green organic and inorganic filler composites were investigated. Various hybrid reinforcements using natural waste fillers including lemon leaves and eggshells were utilized for the study. The tensile strength, tensile modulus, elongation to break, flexural strength, and flexural modulus were investigated for the composites with polypropylene matrix. The results revealed that eggshells composites had the best values for both tensile and flexural tests while lemon leaves composites had the lowest values. However, the hybrid filler (lemon leaves-eggshells) had intermediate values. The poor properties of lemon leaves were attributed to the agglomeration and weak bonding presented by the morphological analysis of the hybrid composites.

The usage of seals in several applications like aircraft engines is mostly made of Fluorocarbon (FKM) elastomer. They are coloured products that enable easier identification based on the applications. In such seals, fillers like carbon black cannot be added to reinforce and improvise the mechanical properties since carbon black does not make it possible to add colours. The properties after ageing are also very critical in sealing application, and they must also be improved. Also, Nanocomposites are the modern and growing trends in the field of polymers that show enormous changes in the properties of the polymers without affecting their basic properties. So, the need for improvisation of FKM seals and the concept of Nanocomposites can be merged to form FKM Nanocomposites with Nano clay and Nano silica as the fillers. The objective of this project is to improve the mechanical properties, better retention of properties after ageing and after fluid interaction of the FKM seals with the aid of Nanofillers. Different proportions of FKM nanocomposites were prepared using modified Nano Kaolin Clay & modified Montmorillonite clay (Cloisite grades). Various mechanical properties like tensile strength, tensile modulus, elongation at break, compression set and tear strength etc., were studied. The test results have shown good improvements while increasing the filler loading. This is helpful to manufacture seals of desired colours thereby avoiding the difficulties faced in the carbon black-filled FKM compounds.

Mineral fillers like talc and mica are commonly used in the plastic industry because of their tendency to alter the properties of thermoplastic materials. Polypropylene (PP)-talc (PTC), PP-mica (PMC), and PP-talc/mica hybrid composites (PHC) were prepared. Results indicated that filler particle size, type, and content greatly influence the mechanical and rheological properties of the composites. Shear viscosity decreased with the increase in shear rate. At 40°C, an increase of approximately 120% in storage modulus ( E′) was observed in PMC composites. C parameter increased, whereas reinforcing efficiency ( r) decreased with the increase in filler loading. Percent elongation of each type of composites decreased with the increase in filler loading. Tensile modulus of PTC composite increased significantly by 103% (571 MPa) at 20% loading of talc, whereas for PHC and PMC composites, increase of 93% (543 MPa) and 81% (511 MPa) was observed. Flexural modulus also increased considerably by 88% (2413 MPa), 80% (2313 MPa), and 62% (2084 MPa) of PTC, PHC, and PMC composites at 20% filler loading.

In this article, we report three nanofillers filled polymer composite systems. Nanofillers composed of alumina, titania and organoclay were embedded separately in 50% polypropylene (PP) and 50% ethylene propylene diene monomer (EPDM) blends. The nanocomposites were prepared using an internal mixer and were molded using a compression mold to form test samples. Effect of filler loading (2, 4, 6, and 8 vol.%) on the tensile properties and melt flow index (MFI) were determined. The mechanical properties of alumina are the highest compared to titania and organoclay. Alumina and organoclay shows an ascending trend in tensile strength with the increase of nanofiller loading. In contrast, the increment of titania filler loading reduces the tensile strength of the nanocomposites. The Young's modulus of the nanocomposites increases with the addition of filler loading. Elongation at break of the nanocomposites shows a descending trend with the addition of filler loading. The addition of 8 vol. % titania and organoclay slightly changes the MFI of the PP/EPDM nanocomposites whereas the addition of 8 vol. % alumina drastically decreased the MFI values. Further addition of nanofillers up to 8 vol. % decreases the MFI values of the PP/EPDM nanocomposites.

The mechanical properties of polypropylene (PP)/waste tire dust (WTD)/kenaf (KNF) composites with and without 3-aminopropyltriethoxysilane (APTES) coupling agent were investigated. The composites were prepared using a Thermo Haake Polydrive internal mixer, where different KNF loading (0, 5, 10, 15, 20 phr) were used. The results revealed that the tensile modulus increased with increasing KNF loading but tensile strength and elongation at break were found decreased. Composites with APTES give higher tensile strength and modulus but lower elongation at break than composites without APTES. The presence of APTES enhanced the interfacial adhesion between PP/WTD matrices and KNF which result in higher tensile strength and modulus of the composites. These findings were supported by the morphological study of the tensile fractured surfaces of the composites.
