“…In fact, a similar variation of R2 and R3 against thickness can also be observed in poplar/HDPE plywood (Fang et al 2013a). Consequently, the present result would be connected with different interface interactions between wood-based panel and fiber reinforced thermoplastic (Lei et al 2015;Yeh et al 2015).…”

“…On the other hand, due to the lack of flexibility, addition of natural fiber would also undermine the impact toughness of a composite (Zhao 2012). For example, with an increase of rice husk around 0 to 50 wt%, the impact strength of PP composite decreases by over 50% (Yeh et al 2015). Similar variation can be found in bamboo cellulose/PLLA and corn fiber/PLA composite (Lu et al 2014;Luo et al 2014).…”

“…Overall, introduction of silane made a difference for the bamboo plastic system, especially in their dispersion, thus facilitating effective stress transmitting along the interface (Lu et al 2014). It should be noted that the improvement effect of silane KH550 on composite morphology in this case was consistent with KH550 on rice husk/PP, KH550 on corn fiber/PLA, and KH560 treated bamboo cellulose/PLLA composite (Lu et al 2014;Luo et al 2014;Yeh et al 2015). Thermal stability Heat endurance serves as an important reflection of interfacial compatibility Lei et al 2015;Yeh et al 2015).…”

“…However, to the authors' best knowledge, the application of silane to this combination has been barely reported on, with the loading level of natural fiber among previous works generally lower (<50%), thereby failing to make full use of potential resources (Fang et al 2014;Lu et al 2014;Luo et al 2014;Yeh et al 2015). Since data findings and study conclusions (especially the mechanism regarding interfacial bonding) may change greatly under different materials and processes, targeted research on this silane modified bamboo plastic composite is undoubtedly very necessary (Zakikhani et al 2014).…”

To blaze new trails for utilizing forestry processing residue, higher plant content biocomposites were proposed based on a combination of moso bamboo flour/silane KH550/high density polyethylene (HDPE), and the materials were characterized by diffractometry, spectroscopy, microscopy, and calorimetry. During surface modification, reactions between bamboo and silane occurred on the lignin aldehyde group. After 6 wt% KH550 treatment, crystallinity of bamboo was increased by 1.11 %, and melting temperature and enthalpy of the composite rose by 2.37 °C and 5.27 J/g, agreeing with improved interface morphology. Increasing in thickness from 3 to 9 mm, the physical and mechanical properties of composite were improved overall. Bamboo content caused the biggest influence, while thickness swelling exhibited the greatest susceptibility. Increasing the bamboo ratio boosted flexural and tensile properties, but it compromised toughness and water resistance, while silane and moulding parameters featured complicated relationships regarding performances. Combining an artificial neural network (ANN), KH550 3 wt%, moulding temperature of 180 °C, and a time of 8 min endowed 9 mm composites of 70 wt% bamboo with performance comparable to load bearing MDF in GB/T 11718.

A novel monofunctional compatibilizer (OID) was prepared and used as compatibilizer for fabrication of wood‐plastic composites. OID was successfully synthesized by esterification reaction of isophorone diisocyanate and octadecanol as confirmed by Fourier transform‐infrared spectra. After OID modification, the hydrophobicity of wood flour surface was enhanced as indicated by the increase of surface water contact angle. By using OID as compatibilizer, an obvious enhancement of the interfacial adhesion between wood flour and polyolefin was observed by scanning electron microscopy. As a result, the tensile properties of the obtained polypropylene/wood flour composites and polyethylene/wood flour composites were significantly enhanced. Besides, the processability of polyolefin/wood flour composites was also improved by adding OID. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44429.
