“…Above 30% of wood fiber content, tensile strength decreased probably due to the poor interfacial adhesion between matrix and wood fibers. Besides, the difficulty of wetting and weak dispersion of wood fibers in the matrix may increase the melt viscosity of wood fiber composites 29 . The low pressure during the molding process can result in less penetration of the molten polymer into the fiber cavities, which implies limited mechanical interlocking between the fiber and the matrix.…”

Environmental concerns of disposals of automotive, building, or packaging applications enforce researchers to find alternative green materials. Hybrid biocomposites, which consists of both natural/man‐made fibers and biopolymers, can be an alternative to glass fiber‐supported composites. On the other hand, heat and sound insulation are key properties for automotive and building industries and there is limited knowledge about insulation properties of biocomposites. In this study, we produced basalt/beech wood fiber reinforced polylactic acid (PLA) biocomposites by twin‐screw extruder, followed by compression molding. We investigated sound and heat insulation properties as well as mechanical and physical properties. Thermogravimetric analysis, Fourier transform infrared and scanning electron microscopy analyses were carried out for thermal, chemical, and morphological characterization of biocomposites, respectively. Analysis revealed that basalt/wood fiber support improved heat and sound insulation of biocomposites; however, water absorption properties reduced by natural fiber loading. Besides, both tensile and flexural strength of the biocomposites reduced by increasing natural fiber loading.

In our study, the effects of wood waste content (0, 2.5, 5, 7.5, and 10 wt.%) on thermal and dry sliding wear properties of poly(lactic acid) (PLA) biocomposites were investigated. The wear of developed composites was examined under dry contact conditions at different operating parameters, such as sliding velocity (1 m/s, 2 m/s, and 3 m/s) and normal load (10 N, 20 N, and 30 N) at a fixed sliding distance of 2000 m. Thermogravimetric analysis demonstrated that the inclusion of wood waste decreased the thermal stability of PLA biocomposites. The experimental results indicate that wear of biocomposites increased with a rise in load and sliding velocity. There was a 26–38% reduction in wear compared with pure PLA when 2.5 wt.% wood waste was added to composites. The Taguchi method with L25 orthogonal array was used to analyze the sliding wear behavior of the developed biocomposites. The results indicate that the wood waste content with 46.82% contribution emerged as the most crucial parameter affecting the wear of PLA biocomposites. The worn surfaces of the biocomposites were examined by scanning electron microscopy to study possible wear mechanisms and correlate them with the obtained wear results.

“…This trend in increasing density with wood waste/rice husk was anticipated due to the use of high-density rice husk content to replace the low-density PLA. Meanwhile, the decrease in the density of wood-waste-filled PLA biocomposites was attributed to the lower density of wood waste compared to PLA [65]. The highest density of 1.277 g/cm 3 was recorded for the p-5 alternative, with 10 wt.% wood waste/rice husk, while density remained the lowest (1.183 g/cm 3 ) for the p-9 alternative, with 10 wt.% wood waste content.…”

Based on the criteria importance through inter-criteria correlation (CRITIC) and the multi-attributive border approximation area comparison (MABAC), a decision-making algorithm was developed to select the optimal biocomposite material according to several conflicting attributes. Poly(lactic acid) (PLA)-based binary biocomposites containing wood waste and ternary biocomposites containing wood waste/rice husk with an overall additive content of 0, 2.5, 5, 7.5 and 10 wt.% were manufactured and evaluated for physicomechanical and wear properties. For the algorithm, the following performance attributes were considered through testing: the evaluated physical (density, water absorption), mechanical (tensile, flexural, compressive and impact) and sliding wear properties. The water absorption and strength properties were found to be the highest for unfilled PLA, while modulus performance remained the highest for 10 wt.% rice husk/wood-waste-added PLA biocomposites. The density of PLA biocomposites increased as rice husk increased, while it decreased as wood waste increased. The lowest and highest density values were recorded for 10 wt.% wood waste and rice husk/wood-waste-containing PLA biocomposites, respectively. The lowest wear was exhibited by the 5 wt.% rice husk/wood-waste-loaded PLA biocomposite. The experimental results were composition dependent and devoid of any discernible trend. Consequently, prioritizing the performance of PLA biocomposites to choose the best one among a collection of alternatives became challenging. Therefore, a decision-making algorithm, called CRITIC–MABAC, was used to select the optimal composition. The importance of attributes was determined by assigning weight using the CRITIC method, while the MABAC method was employed to assess the complete ranking of the biocomposites. The results achieved from the hybrid CRITIC–MABAC approach demonstrated that the 7.5 wt.% wood-waste-added PLA biocomposite exhibited the optimal physicomechanical and wear properties.
