“…Adding a coupling agent may facilitate the formation of a good interfacial interaction of natural fiber composites and lead to sufficient bonding between them and efficient load bearing capability from the fibers to the interface. [32] The composites prepared using the KH560-treated OWF exhibited the best mechanical properties. The increments in tensile strength caused by KH560 treatment were 5.8%, whereas those in flexural strength and flexural modulus were both 1.4%.…”

Environment friendly composites with favorable mechanical properties and low water absorption performance were successfully produced from poly(lactic acid) (PLA), office waste paper fiber (OWF), and coupling agents. The perfect sample was easily manufactured by melting–blending and injection molding. The PLA/OWF composites were comparable with other PLA/plant fiber composites, and the results indicated that the PLA/OWF composites show better performance than PLA/wheat straw fiber composites and PLA/bamboo fiber composites. On this basis, influence of modification of OWF on the properties of composites was investigated. The infrared results show that the OWF modification by different coupling agents was successful, and the scanning electron microscopy indicates that prepared composites exhibit good interfacial compatibility due to preferable binding force between fiber and matrix. With addition of 2 wt% γ‐(2,3‐propylene oxides)propyl trimethylsilane, the composite exhibits high tensile strength of 58.96 MPa, reflecting increase of 14% than the pure PLA. According to the crystallization and melting performance table, OWF can act as nucleating agent to promote the crystallization properties on composites, while the coupling agents have little effect on thermal stability. This article confirmed that the OWF has appropriate properties and is suitable for preparing composite materials and this work provides a novel idea for the utilization of office waste paper.

“…15,16 This often necessitates surface modification, especially to improve interfacial bonding and fiber dispersion. 17,18 On the other hand, synthetic fibers have stronger mechanical properties than natural fibers and PLA composites reinforced with synthetic fibers have been reported to show far superior mechanical performance compared to natural fiber reinforced PLA composites. 19,20 Some of the notable synthetic fibers suitable for use with PLA include glass fiber (GF), carbon fibers, and carbon nanotubes.…”

Herein, glass fiber (GF) reinforced binary, ternary, and quaternary poly(lactic acid) (PLA) composites were prepared. Toughening, and chain extension of PLA was achieved through the incorporation of impact modifier and chain extender and their concurrent effects on the spectroscopic, crystallization, mechanical, thermal, and thermomechanical properties of the composites were investigated. High mechanical properties of GF influenced the mechanical performance of the composites. However, GF alone could not restrict the chain mobility of PLA due to poor interface and low crystallization activities in the PLA-GF composite. Incorporation of impact modifier and chain extender produced significantly enhanced interaction between GF and PLA. Significantly, the crystallinity, impact strength, and flexural modulus of PLA in the quaternary composite were increased by 58%, 63%, and 66%, respectively. In addition, damping and effectiveness coefficient of the PLA-GF composite were notably reduced by the simultaneous impact modification and chain extension of the reinforced composites.

“…This make natural fibers a good candidate as fillers in composite made by biopolymers. In particular, great attention was paid to the preparation of bio-composite made by PLA and different types of natural fibers such as flax [14][15][16][17], kenaf [18][19][20], jute [21][22][23], hemp [24], palm fibers [25]. However, some drawbacks are needed to be solved for the expansion of these bio-composite like limited mechanical durability, excess water absorption and poor thermal properties [26].…”

According to the European Bioplastics association, in 2017, the so-called bioplastics represented only 2.06 million tons of the 320 million tons of plastics produced annually [1]. The global production capacity is expected to increase up to 2.62 million tons in 2023. This growth is pushed by the demand of more sophisticated biopolymers, new applications and products. From packaging, agriculture, consumer electronics, textile to automotive, bioplastics are used in an increasing number of applications. In fact, biopolymers offer a number of additional advantages if compared to conventional plastics, such as a reduced carbon footprint and additional waste management options. Among bio-based and biodegradable plastics, polylactic acid (PLA) is one of the most interesting ones due to their good mechanical properties, good workability, excellent barrier properties. Therefore, it is a good candidate for the replacement of polystyrene (PS), polypropylene (PP), and acrylonitrile butadiene styrene (ABS) in many applications. However, PLA presents some weak points mainly represented by its low ductility, poor toughness, low glass transition temperature, high sensitivity to moisture and relatively low gas barrier, that limit its use in packaging applications [2, 3]. Indeed, the main
