The thermal degradation of high density polyethylene (HDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ banana skin powder (BSP) composites with and without ENR-50 are fabricated and studied. The thermal degradation of this composite was evaluated for 30 days oven ageing. The BSP with size of 150 – 300 μm was utilized in this work. All compounds were mixed using heated two roll mill at 180 °C. The compounds were molded in a hot press machine at 180 °C for 11 minutes to produce 1 mm thin sheet. Then the sheet were cut into dumbbell shape for the mechanical testing using universal testing machine. The tensile strength of high density polyethylene/ recycled acrylonitrile butadiene rubber/ banana skin powder composites showed the decreasing trend with the increasing NBRr loading for the composites with and without ENR-50. However, the result for the oven ageing showed lower tensile strength. This may due to the chain session of PP matrix at heat exposure duration of 30 days.

The compatibilizer effect of ENR-50 on the tensile properties of high density polyethylene (HDPE)/recycled acrylonitrile butadiene rubber (NBRr)/banana skin powder (BSP)/ composites has been studies. HDPE/NBRr/BSP composites were prepared by melt mixing technique using twin-screw at 180 °C for 9 minutes at rotor speed 50 rpm. The six different composites studied were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. As for compatibilized composite a fix 5 wt% of ENR-50 was evaluated. The specimens were analysed for tensile strength and elongation at break (Eb). The results showed that tensile strength and the elongation at break were decreases with the increasing of NBRr loading. However for ENR-50 compatibilized composites, higher tensile strength and elongation at break was recorded. The ENR-50 was found to be an excellent compatibilizer for HDPE/NBRr/BSP composites.

The thermal degradation of linear low density polyethylene (LLDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ rice husk powder (RHP) composites with and without epoxidized nature rubber (ENR-50) were studied. The thermal degradation of this composite was evaluated for 30 days using oven ageing. The NBRr content was manipulated in this work and the particle size for the rice husk powder was 150-300 μm. The composites were prepared by using two-roll mills at 180 °C and then were compressed at 180 °C to produce a 1 mm thin sheets. The dumbbell samples then were analysed by using universal testing machine and field emission screening electron microscopy for tensile and morphological properties. The results obtained showed that tensile strength was decreased with the increasing of NBRr content for both oven ageing and control composites. However the oven ageing composites recorded much lower tensile properties. This may possibly due to the chain session of LDPPE matrix at longer heat exposure duration. This finding is supported by the morphological micrograph with less ductile features of the respective specimens.

Abstract The objectives of this study were to examine the effects of fiber content and extrusion parameters on polybenzimidazole (PBI) fiber-reinforced polyethylene composites and to determine the optimum values for the tensile strength. The PBI fiber was physically mixed with high density polyethylene (HDPE) and then extruded through a twin screw extruder. The extrusion parameters were studied at different levels, barrel temperatures at 240°C, 250°C and 260°C and screw speeds at 12 rpm, 15 rpm and 18 rpm. The tensile strength was measured using a universal testing machine. A response surface experimental design using Design-Expert was applied to investigate the effect of fiber loading and extrusion parameters (barrel temperature, screw speed) on tensile properties of the resulting composite and consequently analyzing the optimized value for these parameters to yield maximum tensile strength. The analysis predicted a linear model which suggests that in order to achieve maximum tensile strength the screw speed should be 18 rpm, the barrel temperature at 240°C and at a fiber loading of 2%.

Polypropylene (PP)/ recycled acrylonitrile butadiene rubber (NBRr)/ banana skin powder (BSP) composites with different BSP filler loading (5,10,15,20,25,30wt. %) were studied. Composites were prepared by using heated two roll mill at 180 °C. The effect of 3-aminopropyltrimethoxysilane (APS) as coupling agent were evaluated. Mechanical properties such as tensile strength, Young’s Modulus and Elongation at Break (Eb) of the different composites were investigated. Tensile strength and Elongation at break of the composites were found to be decreasing with increasing BSP filler loading. The Young’s Modulus was found to be increasing with BSP filler loading due increment of composite rigidity. At similar BSP filler loadings, γ-APS treated BSP composites shows higher tensile strength and Young’s Modulus. This may due to strong bonding between BSP filler and PP/NBRr matrices in the presence of APS silane coupling agent. The morphological studies strongly support this findings whereby good interaction and less pull outs of BSP filler was noticed in the presence of APS silane.

Abstract Modified montmorillonite was used as filler for NBR. The effect of the montmorillonite structure and its concentration was studied. The composites were prepared with the use of a laboratory two-roll mill. Unmodified montmorillonite (MM_Na) agglomerated in NBR rubber resulting only in small enhancement of mechanical properties. The most effective exfoliation of the montmorillonite was observed for the modifier with two long chains (dihydrotallowdimethylammonium chloride (2M2HT)) and at its higher concentration (C1). The modified filler did not agglomerate in NBR. The montmorillonite (MM_2M2HT(C1)) formed a secondary filler network. This very well dispersed network demonstrated the strong reinforcement. Increasing the content of MM_2M2HT(C1) to 20 parts by wt. improved significantly the tensile strength of NBR vulcanizates (tensile strength > 25 MPa). Montmorillonite intercalated with hydrotallowdimethylbenzylammonium chloride (MM_2MBHT) did not improve the properties of the studied materials.
