“…59 The alkaline treatment may lead to an increase in surface hardness, and thus increases the wear resistance of the composite. 60 Perhaps, low alkaline concentration on the composite sample improves surface roughness, strengthens the interfacial bond, thereby resisting abrasive wear as also observed in Figure 9 below. Figure 9 is a micro-morphology of an abrasive wear of SWC and SKC in order of increases in alkaline concentration, SWC (Figure 9(a) untreated, (b) 3% alkaline-treated and (c) 7% alkaline-treated) and SKC (Figure 9(d) untreated, (e) 3% alkaline-treated and (f) 7% alkaline-treated).…”

Wood-plastic composites are being widely used more and more, and the bonding strength between fillers and matrix is an important factor affecting the properties of wood-plastic composites. In this study, rapeseed straw and rapeseed stalk were pretreated with sodium hydroxide and then filled with polyvinyl chloride matrix to prepare composites. The chemical composition, thermal stability, microstructure, physical properties, mechanical properties, and abrasive wear resistance of the composites were characterized, and the effects of different concentrations of alkaline treatment on rapeseed straw composite and rapeseed stalk composite were revealed. The results show that alkaline treatment has no significant effect on the chemical composition of the composites but has an obvious effect on other properties. Among them, after 1% alkaline treatment, rapeseed straw composite has the highest hardness, thermal stability, and impact strength, rapeseed stalk composite has the highest impact strength and bending strength. After 3% alkaline treatment, rapeseed straw composite has more wear resistance, rapeseed stalk composite has the highest density, the highest tensile strength, and more wear resistance. The rapeseed straw composite with 5% alkaline treatment has the highest density, and the rapeseed stalk composite with 7% alkaline treatment has the highest thermal stability. The hardness of rapeseed stalk composite and the tensile strength and bending strength of rapeseed straw composite decreased with the increase of alkaline treatment concentration.

“…Many studies have focused on the aging of composites under different conditions, such as xenon lamp aging [9,10], ultraviolet aging [11,12], bacterial aging [13,14], and seawater and acid rain aging [15,16]. Soil aging is a common aging type, and improving aging resistance is significant for the application of composites [17,18].…”

To study the effect of accelerated simulated soil aging on the physical, mechanical, and thermal behavior of rice husk fiber-reinforced polyvinyl chloride composites. The worst soil aging condition was determined using the orthogonal design method, and the physical, mechanical, and thermal properties of the composites were analyzed over 21 d. The results indicate that the worst soil-accelerated aging condition was as follows: soil temperature of 65°C, soil pH of 2.5, soil moisture content of 45%, and soil porosity (ratio of thick to thin) of 3 : 7. An extended aging time tends to cause poor interfacial bonding quality, and the presence of many microcracks reduced thermal stability and flexural and impact strength. Many fibers were exposed, which resulted in increasing 24 h water absorption and thermal expansion coefficient. The hardness, tensile strength, flexural strength, impact strength, and pyrolysis temperature of the composites (after 21 d of aging) decreased from 50 HRR, 17.42 MPa, 35.2 MPa, 3.19 kJ/m2, and 258.5°C to 26 HRR, 11.5 MPa, 16.8 MPa, 1.16 kJ/m2, and 251.3°C, respectively. The mass loss rate, 24 h water absorption, discoloration, and line thermal expansion coefficient of the composites increased from 0%, 4.19%, 0, and 28.43 to 2.9%, 7.92%, 29.03, and 29.98, respectively.

Wood‐plastic composites are attracting great interest from society due to their recycling nature and excellent processability. Also, nano silica can be used as reinforcing filler for wood‐plastic composites. However, it is difficult to achieve a fine nano silica dispersion within the wood‐plastic composites. In this article, the alkali treatment and sol‐gel method were combined to modify the wood flour(WF) in situ to prepare WF/silica hybrid, and the hybrid was used as reinforcing filler for polypropylene‐based wood‐plastic composites. The physicochemical properties of WF/silica hybrid were characterized by infrared spectroscopy, scanning electron microscopy and thermogravimetric analysis. Subsequently, the mechanical properties, Vicat softening temperature, oxidation induction time and thermal decomposition behavior of polypropylene‐based wood‐plastic composites were characterized. The test results were compared with polypropylene‐based wood‐plastic composites blended with nano silica. Compared with the wood‐plastic composites blended with commercial silica, the composites filled with hybrid filler have better mechanical performances and thermal stability. The addition of hybrid is also beneficial to improving the thermal oxygen resistance of the composites. We envision that the present work offers novel insights to prepare high‐performance wood‐plastic composites.
