Polymer blending is one of the methods used to improve some insufficient properties of conventional polymers. The objective of this work was to study the effectiveness of CR content on the tensile properties and morphology study of recycled polypropylene (rPP)/ chloroprene rubber (CR) blends. The results indicated that the tensile strength and modulus of elasticity of rPP/CR blends decreased, however elongation at break increased as increasing CR content. The morphology study of rPP/CR blends showed the incompatibility between rPP and CR with the detachment of CR particles and CR particles pulled out from rPP surface.

This research focused on the utilization of kapok husk (KH) as filler in low linear density polyethylene (LLDPE). The effect of filler content on tensile properties and morphology of LLDPE/KH eco-composites were investigated. The eco-composites were prepared by using Brabender Plasticiser EC Plus at temperature 160 °C and rotor speed 50 rpm. The results indicated that the tensile strength and elongation at break decreased with KH content increased. However, the modulus of elasticity increased with increasing of KH content. The morphology study of eco-composites exhibit poor interfacial adhesion between KH and LLDPE.

Effects of alkanolamide (ALK) addition on cure characteristics, swelling behaviour and tensile properties of silica-filled natural rubber (NR)/chloroprene rubber (CR) blends were investigated. The ALK was synthesized from Refined Bleached Deodorized Palm Stearin (RBDPS) and diethanolamine, and incorporated into the silica-filled NR/CR blends as a non-toxic rubber additive. The ALK loadings were 0.0, 1.0, 3.0, 5.0 and 7.0 phr. It was found that the ALK exhibited shorter scorch and cure times and higher elongation at break of the silica-filled NR/CR blends. The ALK also exhibited higher torque differences, tensile modulus and tensile strength at a 1.0 phr of ALK loading and then decreased with further increases in the ALK loading. The swelling measurement proved that the 1.0 phr loading of ALK caused the highest degree in crosslink density of the silica-filled NR/CR blends.

Satisfactory Quality

The reprocessing ability of recycled polypropylene (PP) has been investigated to evaluate the recycling feasibility in spur gear production. Up to 15 reprocessing cycles have been performed by injection moulding, and the effects on tensile properties including ultimate tensile strength, Young’s modulus and elongation at break have been studied. Results revealed that reprocessing ability of recycled PP spur gears could yield satisfactory quality as attractive as that corresponding to the virgin PP spur gear. The recycled PP gears resulted in more 10% variation in tensile properties during multiple processing. This effort might be a contribution to convince the industry to apply recycling of PP by means of multiple reprocessing in gear manufacturing.

The aim of this study is to produce PLA nanocomposites by solvent casting incorporating Montmorillonite nanoclays (MMT) and titanium dioxide (TiO2) nanoparticles. The effects of difference loadings of MMT in PLA and different loadings of TiO2 on mechanical and morphology properties were studied. The nanocomposites were prepared by solvent casting at different loadings of MMT (0, 2, 4, 6 and 8 wt %) and different loadings of TiO2 (1 and 3 wt %) respectively. The properties such as tensile properties (tensile strength, elongation at break, and modulus of elasticity) and morphology were determined. The results indicate that 4 wt% of MMT loading produced the best tensile properties. However, the incorporation of TiO2 showed an improvement in the modulus of elasticity of PLA/MMT nanocomposites mainly at 1 wt % loading of TiO2.

Nowadays bioplastics is the most recent study materials as the substitute for conventional plastics. The interest in bioplastics has lead to the production of polylactic acid (PLA) biocomposite films. In this study the PLA/Corn husk (CH) biocomposite films were prepared by using solvent casting method and the effect of CH content on the tensile properties were studied. The result found that increasing of CH content decreased the tensile strength and elongation at break of the biocomposites film. While, the modulus of elasticity increased with the increasing of CH content in the PLA matrix.

Soy protein isolate (SPI)/kapok husk (KH) based biofilms were prepared by casting method. The effect of phthalic anhydride (PA) content on tensile properties and morphology were studied. The PA was use as a crosslink agent. It was found that the increasing PA content have increased the tensile strength and modulus of elasticity of biofilms, whereas the elongation at break decreased. At 1.5 % of PA showed the highest tensile strength and modulus of elasticity of crosslink biofilms. The morphology study indicates the crosslinking with PA improved the interfacial interaction between KH and SPI matrix.

Polypropylene/Cocoa Pod Husk (PP/CPH) biocomposites with different maleated polypropylene (MAPP) content were prepared via melt blending process using Brabender Plastrograph mixer. The tensile strength and tensile modulus of PP/CPH biocomposites increased with increasing of MAPP content. The PP/CPH biocomposites with 5 phr of MAPP showed the optimum improvement on tensile properties. However, the increased of MAPP content reduced the elongation at break of PP/CPH biocomposites. At 5 phr of MAPP content, PP/CPH biocomposites showed lowest elongation at break. Scanning electron microscope confirms the PP/CPH biocomposites with MAPP have better filler-matrix interaction and adhesion due to the effect of MAPP.

The novel packaging was synthesised by coating polyvinyl chloride (PVC) film with Polyvinylamine/Polyvinyl alcohol (PVAm/PVA) mixture which can effectively inhibit the migration of DOP in this paper. The effect of PVAm/PVA mixture on inhibiting DOP migration was detected via extraction tests. The results showed that the novel packaging significantly reduced the migration rate of DOP compared with the control (PVC film). After 24h extracted by hexane 40% PVAm in mixture being coated on PVC had the lowest migration rate (6.20%) among the samples, while 7.60% is the migration rate of control sample. Tensile properties analysis indicated the elongation at break and tensile strength of samples coating PVAm/PVA higher than control sample. The thermogravimetric analysis demonstrated that the PVAm/PVA mixed solution can deduce thermogravimetric rate. Therefore, coating PVC with PVAm/PVA mixture is an effective approach to suppress the migration of DOP.

The cure characteristics, swelling behaviour and tensile properties of carbon black (CB)-filled natural rubber (NR)/chloroprene rubber (CR) blends in the presence of alkanolamide (ALK) were investigated. The NR/CR blends were prepared at 50/50 blend ratio. The ALK was prepared from Refined Bleached Deodorized Palm Stearin (RBDPS) and diethanolamine and added into the CB-filled NR/CR blends as a rubber additive. The ALK loadings were 0.0, 1.0, 3.0, 5.0 and 7.0 phr. It was found that the ALK exhibited shorter scorch and cure times and higher elongation at break of the CB-filled NR/CR blends. The ALK also exhibited higher torque differences, tensile modulus and tensile strength up to 5.0 phr of ALK and then decreased with further increases in the ALK loading. The swelling test proved that the 5.0 phr loading of ALK caused the highest degree in crosslink density of the CB-filled NR/CR blends.

Two Factors

The object of this work is to study and predict the tensile properties (tensile strength, elastic modulus, and elongation at break) of ternary nanocomposites based on epoxy/glass fiber/nanosilica using the fuzzy logic (FL). Two factors in three levels including glass fiber at 0, 5, and 10 wt% and nanosilica at 0, 0.5, and 1 wt% were chosen for adding to an epoxy matrix. From FL surfaces, it was found that the glass fiber content had a main role in the tensile properties of nanocomposites. The high levels of glass fiber content led to a significant increase in the elastic modulus and generally, the presence of glass fiber decreased the tensile strength and elongation at break. Also, addition of the nanosilica content resulted in an increased elastic modulus but decreased the elongation at break of nanocomposites. Finally, an FL model was obtained for each tensile property.
