“…This result demonstrated that the coupling agent provides strong interfacial adhesion (Poletto et al 2014, Turku et al 2017. In addition, the good wetting between the wood flour and rPS matrix for treated composites shown in Figure 3(b) corroborates the higher mechanical properties observed in Table 1, since the applied stress can be better transfer from the matrix to the reinforced fibers improving the composite performance (Poletto et al 2014, El-Sabbagh 2014, Naghmouchi et al 2015. …”

In this work, the potential for usage recycled polystyrene and wood flour wastes as materials for development wood plastic composites was evaluated. The effects of wood flour loading and coupling agent addition on the mechanical, dynamic mechanical and morphological properties of polystyrene wood flour composites were examined. The results showed that the mechanical properties decreased with the wood flour loading. However, an improvement in composite compatibility was observed when the coupling agent was used resulting in the increase of mechanical and dynamic mechanical properties. A morphological study demonstrates the positive effect in the interfacial adhesion between filler and matrix caused by the coupling agent addition. Based on the findings of this work, both waste materials can be used for development composites with higher performance.

“…They present several interesting advantages, particularly their low density, high specific stiffness and strength, biodegradability, their renewable character, their low processing energy in the case of chopped natural fibers, and their availability everywhere at modest cost and in a variety of morphologies and dimensions. All these properties make them convenient materials for matrix reinforcement, such as polymer composites, as witnesses the significant number of recent reviews and publications [3][4][5][6][7][8][9] .

The objective of the present study was to evaluate lignocellulosic particles from sub-products of the coffee industry (coffee parchment -CP and husk -CH) into polyhydroxybutyrate (PHB) as a promising reinforcing filler in the biocomposites. The effects of type (CP or CH) and content (neat, 10% and 20%) of coffee wastes on the thermal, mechanical, microstructural and physical properties of the ensuing composites were evaluated. Thermal stability of the composites was improved by the coffee residues at different contents, while degree of crystallinity was decreased with the inclusion of CP. The addition of 10% of CP has not influenced significantly the tensile strength (TS) and Izod strength (IS), in relation to the neat PHB. Tensile strength (TS), MOE and Izod strength (IS) of the composites have increased significantly with the inclusion of 20% of CP. The increase in the content of coffee waste particles increased the water absorption of the composites.

“…For wood plastic composites, the tensile strength increases slightly when a filler is added (up to 16 % with a 30% w/w and MAPP), or slightly decreases when no MAPP is used (Naghmouchi et al 2015). Only one study has reported on compression-molded composite materials reinforced with sugarcane bagasse sawdust , but this study does not provide the tensile strength of the PP matrix, making it difficult to predict the behavior of the composite.…”

Sugarcane bagasse was treated to obtain sawdust, in addition to mechanical, thermomechanical, and chemical-thermomechanical pulps. The obtained fibers were used to obtain reinforced polypropylene composites prepared by injection molding. Coupling agent contents ranging from 2 to 10% w/w were added to the composite to obtain the highest tensile strength. All the composites included 30% w/w of reinforcing fibers. The tensile strength of the different sugarcane bagasse fiber composites were tested and discussed. The results were compared with that of other natural fiber-or glass fiber-reinforced polypropylene composites. Pulp-based composites showed higher tensile strength than sawdust-based composites. A micromechanical analysis showed the relationship of some micromechanical properties to the orientation angle, critical length, the intrinsic tensile strength, and the interfacial shear strength. The pulps showed similar intrinsic tensile strengths and were higher than that of sawdust. The properties of the sugarcane bagasse composites compared well with other natural fiber-reinforced composites.
