“…All the treated sawdust composites showed higher flexural strength than the raw sawdust composites. Furthermore, from Figure 5, the flexural modulus is increased with filler loading increased which is in agreement with the other researcher [15,21,22]. It is found that the flexural strength decreased approximately 1.6% respectively over the raw sawdust-PP composites at 10 wt% filler loading, while for the 15 wt% -25 wt% filler loading, the flexural strength gradually increase approximately from 6.6% -10.8% respectively.…”

“…Figure 3 shows that the addition of WSF contents increased the impact strengths of composites. Similar results were also obtained for different polymer composites containing 3 wt% to 5 wt% natural filler content; higher contents caused the impact strength to drop (Lou et al 2007;Rahman et al 2010;Tawakkal et al 2012;Obasi 2015). The decrease in impact strength indicated that the amount of matrix was probably not sufficient to transfer the stress effectively during a sudden impact in combination with the lower absorption characteristic of the filler (Tawakkal et al 2012).…”

The goal of this work was to evaluate the technical feasibility of walnut shell flour (WSF) as substitute for wood in walnut shell flour/thermoplastic starch (WSF/TPS) composites. The effects of walnut shell flour (WSF), thermoplastic starch (TPS), and nanoclay on the physical and mechanical properties of WSF/TPS composites were investigated. The composite samples were formed in a Colin extruder with four-chamber heat with temperatures. Then, test samples were made using injection molding. The addition of up to 40% WSF greatly improved the tensile strength, flexural strength, and elasticity modulus of the composite. Also, the composites made with higher WSF contents had increased thickness swelling and water absorption. The incorporation of nanoclay (0% to 5%), greatly improved the tensile properties. Soil burial degradation experiments showed that biodegradation was accelerated by the increase of starch in the composite mixtures. The study showed that WSF can be successfully utilized for the manufacture of composites with useful physical and mechanical properties.

“…The improvement in the dimensional stability can be explained by the fact that the charcoal contains many pores and gaps in its structure. The wood-derived charcoal has small holes lengthwise and crosswise and its inner surface is about 50 m 2 /g [20] . The results of TS and WA tests suggested that the pores and gaps in the structure of charcoal were filled by melted polypropylene.…”

Effect of Wood-derived Charcoal Content on Properties of Wood Plastic Composites

The effect of wood-derived charcoal flour on the water resistance and mechanical properties of wood plastic composite (WPC) panels was investigated. The hot press molded WPC panels were produced from polypropylene (37 wt%) with maleic anhydride-grafted polypropylene (MAPP, 3 wt%) and different mixtures of wood flour and charcoal flour. The amount of charcoal flour was gradually increased up to 60 wt%. The thickness swelling and water absorption of WPC panels considerably decreased with increasing charcoal flour content. The internal bond strength and bending properties of the WPC panels significantly improved with increasing charcoal flour content. This was mainly attributed to the high amount of pores and gaps in the charcoal flour. Melted polypropylene could get into the pores and gaps during the hot press molding, which lead to a better interfacial adhesion between polymer matrix and wood filler. The results showed that the charcoal flour could be partially substituted for the wood flour in the production of WPC panels having higher dimensional stability and internal bond strength.
