Properties Of Composites

In the research, old newspaper recycling fiber-reinforced polylactic acid composites were produced by using injection molding technology. The influences of MAPP coupling agent and newspaper alkali deinking treatment on the performance of composite materials were studied. The results showed: MAPP can effectively improve the compatibility of old newspaper recycling fibers and PLA and increase the mechanical properties of composites; the alkali deinking treatment can effective improve the adhesion of newspaper recycling fibers and PLA and increase the mechanical properties of composites.

Properties Of Composites

Rice straw/Poly(butylene succinate)(PBS) composites were prepared by injection molding machine. The influence of content and particle size of rice straw on the mechanical properties of composites indicated that with the increase of rice straw content the tensile strength and fracture strain of the composites was decreased. With the same content of rice straw, the smaller particle size, the more obvious decreased. The influence of dosage of silane coupling agent(SCA) on the composites was studied, the result indicated that with the increase of SCA content, the interface of composite materials significantly improved, the Young’s modulus increased 362% after rice straw was treated by SCA. Thermal analysis showed that the adding of coupling agent didn’t undermine the thermodynamic stability of the composites.

Flexible Film

A flexible film was obtained from a blend of cassava thermoplastic starch and polylactic acid, using maleic anhydride as coupling agent. For this, an experimental design with three factors was used: polylactic acid content, coupling agent content, and temperature profile of the blown extrusion. It was found that the three factors generated significant differences on the response variables of tensile mechanical properties individually as in their triple interaction. Differential scanning calorimetry (DSC) was used by understanding the behavior of thermal properties of TPS/PLA blends with and without coupling agent, finding similar results between both. From this, the combination with 28% polylactic acid, 0.87% coupling agent, and 155.75°C temperature profile permitted the obtaining of a material with outstanding mechanical properties and offered advantages from the economic point of view.

The Impact

The nanocellulose fibril produced by using natural sources can be used in developing sustainable and green products. The useful features of nanocellulose fibril can include valuable physical properties, appropriate surface chemistry, low toxicity, and biocompatibility. The study presented shows the use of polylactic acid with five different percentages of nanocellulose fibril and the use of 3% maleic anhydride as a coupling agent. The maleic anhydride acts as coupling agent which improves the thermochemical and thermomechanical characteristics of the end product. The addition of 3% maleic anhydride as coupling agent with 10% nanocellulose fibril improved the impact strength up to 14.3%, elastic modulus up to 40.6%, and tensile strength up to 30.1%. Furthermore, the dynamic mechanical analysis result indicates that the inclusion of maleic anhydride improved the toughness by reducing the tan δ peak and increases the storage modulus. Finally, the scanning electron micrograph shows that the interfacial compatibility between nanocellulose fibril and polylactic acid matrix is improved with the addition of maleic anhydride.

Properties Of Composites

In this work, palm fiber reinforced polylactic acid composites were fabricated by hot-compress. The palm fibers were treated by γ-aminopropyl trimethoxysilane (APS) and coated with polylactic acid (PLA) in varied percentage (5%, 10% and 15%). The treatment reaction was analyzed by FTIR and the effect of fiber treatment on the flexural and dynamic mechanical properties of oil palm empty fruit bunch/polylactic acid (OPEFB/PL) composites were examined. The flexural properties of composites were increased with increasing of fiber coating and improved by introduction of APS. It was also observed that the APS treated fibers had improved the dynamic mechanical properties of the composites respectively.

Properties Of Composites

Effects of wood powder (WP) on mechanical properties of PP/WP composites were studied, and interfacial compatibility between polypropylene (PP) and WP was investigated with SEM. All PP/WP composites were compounded in a parallel twin-screw extruder. Mechanical properties of composites were characterized by tensile, hardness, and impact testing. The result showed that interfacial compatibility in PP/WP composite was ameliorated efficiently by PP-g-(MAH-St) compatilizer, mechanical properties of PP/WP composites were improved by pre-treating WP with alkali and coupling agent. They were also influenced by WP size and WP amount, which were the best at the size of 60-mesh and the amount of 40 wt%.
