“…It is believed that the modulus of elasticity increased with the increasing flexural modulus values of the lignocellulosic material in the polymer composites. Similar results were reported in previous studies (He et al 2015;Pereira et al 2015). Lignocellulosic filled thermoplastic composites usually have been considered as an alternative to the polyolefin-based plastic lumber decking boards.…”

Hazelnut husk was considered as a potential filler for thermoplastic composites. Different amounts of hazelnut husk flour and the recycled high-density polyethylene (R-HDPE) were used as the filler and polymer matrix, respectively. The composite compounds were produced using single-screw extrusion compounding, and then composite panels were prepared by hot-press compression molding. The morphological, physical, mechanical, and thermal properties, as well as the biological durability of the composites, were evaluated. The flexural and tensile modulus of the composites improved with increasing hazelnut husk filler content, whereas the physical properties, biological durability, and the flexural and tensile strengths were reduced. With the addition of a maleic anhydrite-grafted polyethylene (MAPE), the hazelnut husk filler was more finely dispersed within the polymer matrix and the degree of crystallinity was lower than that of the R-HDPE. This research revealed that hazelnut husk flour has potential for use as a filler in R-HDPE composites.

“…These results indicate that KH550 can improve the stiffness as well as the toughness of wood flour/PP composites, while too much KH550 causes the weakened mechanical properties of them. The composites with 2% KH550 show a comparable comprehensive mechanical property in the test [29]. Table 2 shows the mechanical properties for the samples (I 0 , I 1 , I 2 , and I 3 ).…”

Subcritical fluids assisted reactive extrusion is a novel and promising alternative technique for preparation of wood plastic composites. Because subcritical fluids have moderate process condition, well swollen performance, and excellent dissolvability. Therefore, subcritical fluids are led into the extruder system to alleviate the thermal degradation of wood flour, to reduce the melt viscosity of matrix, and to strengthen the mass transport. The wood flour is expanded in the presence of subcritical ethanol, which favors the permeability. Fourier transform infrared spectroscopy confirms that maleic anhydride grafted polypropylene (PP‐g‐MA) is grafted onto cellulosic chain, and subcritical ethanol promotes the grafting and swollen reaction. A possible mechanism is proposed to explain the effect of subcritical ethanol on the interfacial reactions. In addition, the thermal stability of wood flour, PP, and wood flour/PP composites are studied. Fracture morphology is observed to confirm the interfacial adhesion of wood flour/PP composites. The results suggest that subcritical ethanol leads to a change of crystalline structure of cellulose via X‐ray diffraction. Moreover, the mechanical properties of wood flour/PP composites increase dramatically, while 3‐Aminopropyltriethoxysilane (KH550) is used as co‐solvent dissolving in ethanol. Experimental results reveal that wood flour/PP composites in the presence of subcritical ethanol with 2% KH550 (190°C, 2.4 MPa, and 120 r/min), whose tensile strength, flexural strength, flexural modulus, and non‐notched impact strength increase by 45, 56, 29, and 36%, respectively, possess the best physical properties comparing to those during extrusion without fluids.

The cellulose fiber was extracted from the abandoned crop sugarcane bagasse (SCB) by means of chemical treatment methods. Poly(lactic acid) (PLA) bio‐based composites with SCB were prepared through fused deposition modeling (FDM) 3D‐printing technology, and the morphologies, mechanical properties, crystallization properties, and thermal stability of 3D‐printed composites were investigated. Compared with the neat PLA, the incorporation of SCB into PLA reduces the tensile strength and flexural strength of 3D‐printed samples but increases the flexural modulus. The difference in tensile performance and bending performance is that the tensile strength of 3D‐printed samples is best when the SCB content is 6 wt%, while the flexural modulus continuously decreases as the SCB content increases. Furthermore, the effects of various printing methods on the tensile performance of 3D‐printed samples were explored via modifying G‐code of 3D models. The results indicate that the optimum SCB fiber content is identical for all printing methods except method “vertical.” Due to the fibers and molecular chains are oriented to varying degrees with altering raster angle in 3D‐printed samples, the fully oriented sample printed by method “parallel” has a better tensile strength. Besides, SCB exhibits enough high thermal decomposition temperature to meet requirements for melt extrusion processing of PLA composites, and SCB fiber is capable of promoting the crystallization of PLA.
