The effect of maleic anhydride as a coupling agent on the tensile properties and morphology of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. rHDPE/WF composites with different wood fiber loading and the addition of maleic anhydride were prepared with Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WFM composites with maleic anhydride exhibit higher tensile strength and modulus of elasticity than rHDPE/WF composites. rHDPE/WFM with maleic anhydride composites gave a better interfacial adhesion between the matrix and the fiber than rHDPE/WF composites as evidence using Scanning electron microscopy (SEM).

The effects of benzyl urea into RHDPE/NR/CFF composites with different fibers loading were studied. The composites were prepared using BrabenderPlasticorder at 160 °C with rotor speed of 50rpm. The composites were characterized in respect of their tensile properties and morphology. The results indicated that RHDPE/NR/CFF with benzyl urea composites show higher values of tensile strength, Youngs modulus, but lower elongation at break than RHDPE/NR/CFF composites. RHDPE/NR/CFF with benzyl urea composites gave a better interfacial adhesion between the matrix and the fiber than RHDPE/NR/CFF composites as evidence using SEM.

The effect of salicylic acid as a coupling agent on the tensile properties, and morphology analysis of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. Both composites rHDPE/WF and rHDPE/WFM (treatment with salicylic acid) were prepared using Brabender Plasticorder at temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WFM composites with salicylic acid exhibit higher tensile strength and modulus of elasticity but lower elongation at break than rHDPE/WF composites. The SEM micrographs showed that the wood fiber was more widely dispersed in the rHDPE matrix with addition of ethyl salicylate than rHDPE/WFM.

The effect of phthalic anhydride as a coupling agent on the tensile properties and thermal stability of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied.  Both composites rHDPE/WF and rHDPE/WF/PAH (modified with phthalic anhydride) were prepared using Brabender Plasticorder at a temperature of 160°C and rotor speed of 50 rpm. The result indicated that rHDPE/WF/PAH composites exhibit higher tensile strength and modulus of elasticity than rHDPE/WF composites. It was also found that the addition of phthalic anhydride offers better thermal stability in rHDPE/WF/PAH composites than that of rHDPE/WF composites.

The effect of phthalic anhydride (PAH) as a coupling agent on the tensile properties, swelling behavior, and x-ray diffraction of recycled high density polyethylene/wood fiber (rHDPE/WF) composites were studied. rHDPE/WF and rHDPE/WFPAH composites were prepared using Brabender plasticorder at temperature of 160°C with rotor speed of 50 rpm. The results indicate that rHDPE/WFPAH composites showed higher tensile strength and percentages of equilibrium water absorption, but lower interparticle spacing (d) compared to rHDPE/WF composites.

Preparation of Alpinia galanga agro waste-high density polyethylene (HDPE) composites involved the addition of eco degradant and polyethylene-g-maleic anhydride (PE-g-MA). The Alpinia galanga agro waste fibers at 3, 6, 10 and 15 wt% were compounded in an internal mixer with the addition of 5 wt% MA-g-PE and eco degradant. The composite specimens were prepared using an injection molding machine. The results show that the maximum tensile strength of 33 MPa was obtained for sodium hydroxide (NaOH) & 3-aminopropyltriethoxysilane (3-APE) treated fiber composites with eco degradant and MA-g-PE at 15 wt% fiber loading compared to that of pristine HDPE (28 MPa). All the treated composites show an improvement in tensile strength. This indicates that the treatments using NaOH&3-APE and p-toluenesulfonic acid (PTSA) with addition of eco degradant and PE-g-MA improved adhesion between Alpinia galanga fiber and HDPE matrix. The Scanning Electron Microscopy (SEM) micrographs show the presence of a improved interaction between treated Alpinia galanga fibers and HDPE matrix with the addition of eco degradant and MA-g-PE. Thermal stability of composites was also improved for composites with treated fibers.

This paper describes tensile properties, and morphology analysis of different composition of RHDPE and EVA blends were studied. The main goals are to describe the effect of Caprolactam as compatibilizer used to improve the compatibility between RHDPE and EVA. The RHDPE/EVA blends were prepared at 160°C and the rotor speed of 50rpm in an internal mixer. The tensile strength for RHDPE/EVA blends increased, while adding Caprolactam by 6phr in the blend formulation significantly improved the tensile properties. The SEM micrograph show a better interfacial adhesion between RHDPE and EVA phases for RHDEP/EVA/Caprolactam blends than RHDPE/EVA blends.

In this study, the absolutely recycled plastic wood (ARCPW) was fabricated with post-consumer high density polyethylene (HDPE) and wood flour from the saw mills. The alkaline, silane and maleic anhydride modified polypropylene (MAPP) were used as modifiers to treat wood fiber and improve the interfacial adhesion of ARCPW. Effects of wood fiber length, weight fraction and surface treatment on the mechanical properties of ARCPW were investigated. The flexural fracture surfaces of ARCPW were examined and the fracture mechanism of ARCPW was also analyzed in this paper. The results indicated that ARCPW with wood fiber simultaneously treated by alkaline, silane and MAPP possesses the best mechanical properties. The higher the content of wood fiber, the better the flexural strength of ARPCW. The interfacial adhesion of prepared ARCPW is ideal and a good compatibility between wood fiber and matrix was obtained.

In this study, the effects of fiber loading from 0 vol.% to 15 vol.% and the chemical treatments on the properties of the sisal fiber-reinforced sheet molding compounds were investigated. The chemical treatments were performed with alkali, γ-ammoniapropyl-triethoxy-silane (KH-550) and γ-methacryloxypropyl-trimethoxy-sliane (KH-570), respectively, to improve the interfacial adhesion between sisal fiber and the matrix (unsaturated polyester resin). The changes of surface morphology and sisal fiber functional groups were investigated by scanning electron microscopy and Fourier transform infrared spectroscopic analysis, respectively. Compared to the untreated sisal fiber-reinforced sheet molding compounds, the mechanical property of the treated sisal fiber-reinforced sheet molding compounds increased due to the interfacial enhancement between sisal fiber and the matrix, which could be observed through the scanning electron microscopy images of fracture surface. Moreover, the better interfacial adhesion was also assisted in water absorption resistance and the thermal stability of the treated sisal fiber-reinforced sheet molding compounds. In the chemical treatments, KH-570 treatment was proved to be an effective method to improve the interfacial adhesion between sisal fiber and the matrix.

Styrene Maleic Anhydride

A commercial grade of high-density polyethylene (HDPE) reinforced with nylon 6 fibres of three diameters at levels up to 30 wt% HDPE. The addition of the fibres resulted in improvements in mechanical properties such as tensile strength and flexural strength. Fibres having the least diameter gave the maximum improvement in mechanical properties. Attempts were made to improve the interfacial adhesion between the fibres and the matrix by grafting the matrix with maleic anhydride and also with styrene maleic anhydride. The mechanical properties showed significant improvements as a result of these modifications. The HDPE/nylon composites/blends obtained by recycling the composites also show good mechanical properties.
