The effect of silane treatment on tensile properties and morphology of recycled acrylonitrile butadiene rubber(NBRr)/polypropylene(PP)/rice husk powder(RHP) composites has been studied. Polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder (PP/NBRr/RHP) composite were prepared by melt mixing technique at 180º C for 9 minutes and 50rpm rotor speed using an internal mixer. Five different composites compositions (70/30/0, 7030/5, 70/30/10, 70/30/15 and 70/30/30), with silane treated RHP(treated) and without silane treatment(untreated) was studied. The specimens were analyzed by different techniques i.e. tensile test and scanning electron microscopy (SEM). The result obtained showed lower tensile properties with increasing amount of NBRr content. Lower tensile strength and tensile modulus was exhibited with increasing NBRr content. However higher tensile strength, greater tensile modulus and lower elongation at break in PP/NBRr/RHP was exhibited for silane treated RHP composites compare with untreated RHP. PP/NBRr/RHP composite was found to become more brittle with strong attachment between PP/NBR matrix and RHP filler with silane treatment. Good adhesion between silane treated RHP filler and PP/NBRr matrix was confirmed by the morphological studies.

The compatibilizer effect of ENR-50 on the tensile properties and morphology of linear low density polyethylene (LLDPE)/ recycled acrylonitrile butadiene rubber (NBRr)/ rice husk powder (RHP) composites has been studied. The RHP size utilize in this work is 150 – 300 μm. LLDPE/NBRr/RHP composites were prepared by melt mixing technique at 180 °C for 9 minutes at 50 rpm rotor speed using heated two roll mill. The series of composites investigated were 100/0/5, 80/20/5, 70/30/5, 60/40/5, 50/50/5, and 40/60/5. The composites were analysed by using tensile test and morphology examination. The result showed that the tensile strength of composite was decreased with the increasing of recycled acrylonitrile butadiene rubber (NBRr) content while elongation at break (Eb) were increased. However, the tensile strength and elongation at break result for composites with ENR-50 as compatibilizer showed higher values. The morphological finding supports the tensile properties which indicate better interaction between the RHP filler and LLDPE/NBRr matrix in the presence of ENR-50 compatibilizer.

The effect of silane treatment on processing characteristic and swelling behavior of recycled acrylonitrile butadiene rubber (NBRr)/polypropylene (PP)/rice husk powder (RHP) composites has been studied. Polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder (PP/NBRr/RHP) composite were prepared by melt mixing technique at 180º C for 9 minutes and 50rpm rotor speed using an internal mixer. Five different composites compositions (70/30/0, 7030/5, 70/30/10, 70/30/15 and 70/30/30), with silane treated RHP (treated) and without silane treatment RHP (untreated) was studied. The specimens were analyzed for swelling behavior with ASTM oil No.3 and processing torque of composites was obtained during composite preparation. The results showed that swelling percentage for both composites increased with NBRr content. However the treated composites exhibited lower swelling characteristics. Processing torque of both composites also showed higher torque reading with increasing NBRr content. However the treated composite with silane exhibited much higher torque value for similar composition composites. Better interaction between RHP filler and PP/NBRr matrixs was obtained with treated composites.

By using a semi-efficient sulphur vulcanisation system, the effects of alkanolamide (ALK) addition on cure characteristics, crosslink density and tensile properties of carbon black (CB)-filled styrene-butadiene rubber (SBR) compounds were investigated. The ALK was prepared from Refined Bleached Deodorized Palm Stearin and diethanolamine and added into the CB-filled SBR compounds. The ALK loadings were 1.0, 3.0, 5.0 and 7.0 phr. It was found that ALK decreased the scorch and cure times of the CB-filled SBR compounds. ALK also improved the tensile modulus and tensile strength; especially up to a 5.0 phr of loading. The crosslink density measurement proved that the 5.0 phr of ALK exhibited the highest degree of crosslink density which caused the highest in tensile modulus and tensile strength. Due to its plasticity effect, ALK increased the elongation at break of the CB-filled SBR vulcanisates.

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.

In this study, the response surface methodology was used to investigate the tensile properties of epoxy/graphene nano-platelets/carboxylated nitrile butadiene rubber ternary nanocomposites. Box–Benhken method was used to design experiments for four factors consisting of graphene nano-platelets (at 0, 0.75, and 1.5 wt%), carboxylated nitrile butadiene rubber (0, 5, and 10 wt%), hardener contents (80, 90, and 100 phr), and also different post curing temperature (130, 140, and 150°C). After the samples were prepared, a tensile test was performed to obtain the tensile strength, tensile modulus, and elongation at break of nanocomposites. Moreover, field-emission scanning electron microscopy was used to observe the state of graphene nano-platelets dispersion. The results obtained from the tensile tests showed that increasing the graphene nano-platelets, carboxylated nitrile butadiene rubber, and hardener contents and high post curing temperature reduced the tensile strength. The optimum value of tensile modulus was achieved at low concentration of carboxylated nitrile butadiene rubber and high contents of graphene nano-platelets, whereas maximum elongation at break occurred at high content of carboxylated nitrile butadiene rubber and low concentration of graphene nano-platelets and hardener. In addition, a second-order polynomial model was used to correlate the tensile properties of ternary nanocomposites to the desired factors. Finally, contour plots were used to determine optimum values of the desired factors. It was seen that the presence of 10 wt% of carboxylated nitrile butadiene rubber in the epoxy matrix increased the elongation at break by the considerable amount of ∼49%.

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.

The influencing effects of the content of wood fiber, particle size and content of titanate coupler on the tensile properties of wood fiber (include the pine powder and the rice husk powder )/PVC composites (WPC) were investigated. The results showed that the tensile modulus of WPC are increased, the tensile strength and the elongation at break of WPC are decreased slightly when the wood fiber changed from 30 to 60( phr method) . Between 150μm and 165μm in the size of the diameter, the tensile strength of WPC increased by 11.5%, however it is increased by 5% between 165μm and 315μm. The content of titanate coupler affected significantly, the tensile properties of WPC appeared first increased and then decreased when the content of titanate coupler is increased from 0 to 3.5 shares( phr method). Added the same content of pine powder or rice husk powder, the tensile modulus and the tensile strength of WPC which filled pine powder are bigger, but the elongation at break of WPC which filled rice husk powder are bigger.

The effects of the montmorillonite clay surface modified with 0.5-5 wt% aminopropyltriethoxysilane and 15-35 wt% octadecylamine (Clay-ASO) and polyethylene-g-maleic anhydride (PE-g-MA) on morphology and mechanical properties of poly (lactic acid) (PLA)/acrylonitrile-butadiene rubber copolymer (NBR) blends were investigated and compared. The PLA/NBR blends and composites were prepared by melt mixing in an internal mixer and molded by compression molding. The ratio of PLA and NBR was 80/20 by weight and the Clay-ASO and PE-g-MA contents were 3, 5 and 7 phr. The morphology analysis showed that the addition of Clay-ASO and PE-g-MA at high content could improve the miscibility of PLA and NBR to be homogeneous blends due to the voids in the polymer matrix were decreased. The tensile properties showed Young’s modulus of the PLA/NBR/Clay-ASO composites was more than that of the PLA/NBR blends and Young’s modulus of composites increased with increasing Clay-ASO content, while the tensile strength and strain at break decreased with increasing Clay-ASO content. The incorporation of PE-g-MA 3 phr could improve the tensile strength, stress at break and strain at break of PLA/NBR blends.
