“…Polypropylene has a solubility parameter of 9.4 (cal/cm 3 [14]. It can be observed that the solvent whose solubility parameter is closest to that of polypropylene (9.3) is benzene (9.1), followed by toluene (8.9) and finally xylene (8.8).…”

“…Other than that, the main drawback of the use of natural fibre as fillers is the low processing temperature permissible due to the possibility of fibre degradation and/or the possibility of volatile emissions that could affect the composite properties. Agro-residue or field crop such as cereal straw, flax straw, rice husk, bagasse, cornstalk, wheat straw and corncob which categorized as natural fibres are recently being considered as an alternative for the wood-plastic composites which are at present dominating the natural fibrecomposite market [2,3].…”

Abstract. This study investigates the morphological and physical/end-use properties of corn cob powder-filled recycled polypropylene composites. The composites were prepared by incorporating corn cob powder of particle sizes 150 µm, 300 µm and 425 µm respectively at filler loadings of 5 to 25 wt%. The properties were determined according to standard test procedures. Results showed that the incorporation of corn cob powder as filler resulted to enhancement of water absorption and solvent sorption, which were found to increase with both increase in filler loading and increase in filler particle size, probably due to the hydrophilic nature of corn cob powder. It was also discovered that solvent sorption was most pronounced with benzene, followed by toluene and lastly xylene, in accordance with the relative proximity of their solubility parameters to that of polypropylene. Flame propagation rate was also found to improve by the incorporation of corn cob powder due to its high content of cellulose, a combustible organic matter. However, specific gravities of the composites were found to be lower than for the unfilled polypropylene, an implication that the composites produced are lighter in weight than the unfilled. Specific gravity increased with increase in filler loading but decreased with increase in particle size. The Morphological studies showed increase in the number of spherulites with increase in filler loading and increase in the size of the spherulites with increase in particle size. Further observation showed that the particle sizes and pores sizes detected increased with increase in filler particle size probably due to poor interaction and distribution of coarse particles. It is hoped that this present study will to help place the usefulness of corn cob as filler in the development of thermoplastic composites in future and develop its niche in the scientific record.

“…High-density polyethylene-wood-flour composites were manufactured following the methods described in a previous paper [10]. HDPE, oven-dried wood flour, and coupling agents were dry-blended in a 20L high intensity mixer (Papenmeier, Type TGAHK20) for 5 min.…”

The performance of fiber reinforced thermoplastic composites strongly depends on solid fiber-matrix adhesion to allow stress transfer between the phases. Fiber surface modification with coupling agents is generally needed to induce bond formation between the fiber and the polymer. This study investigated the effects of coupling agent's functional monomer (acrylic acid vs. maleic anhydride) and base resin (polyethylene (PE) vs. polypropylene (PP)) types on the tensile and flexural properties of high-density polyethylene (HDPE)-wood-flour composites. The interfacial adhesion between wood flour and HDPE matrix was examined using environmental scanning electron microscope. The experimental results indicate that the types of functional monomer and base resin are important factors determining the effectiveness of functionalized coupling agents for HDPEwood-flour composites. Maleic anhydride-functionalized polyolefins perform better than acrylic acid counterparts whereas PE-based maleated coupling agents are more effective than PP-based counterparts in improving the strength properties of HDPE-wood-flour composites.

“…About 2.5 billion kg of fillers are currently used in plastic industry (Caulfield et al, 2005, La Mantia et al, 2005and Clemons, 2002. This provides rigidity and resistance to temperature (Abu-Sharkh et al, 2004 andMengeloglu et al, 2000) but costly and abrasive to the processing equipment (Mengeloglu and Matuana, 2003). The interest in using plastic as binder in composite board is attributed to its properties displayed and recently, organic fillers produced from wood or agricultural plants have gained tremendous attention from plastic industry.…”

Abstract.As noted wood flour species plays an important role in the properties of the resulting composites. The effect of wood species as filler and reinforcement agent on physical and mechanical properties of the WPC was investigated. The used wood species in this study were Ceiba pentandra; Triplochiton scleroxylon and Entandrophragma cylindricum at plastic/wood ratio of 1:2.3, 1:1.5 and 1:1 (w/w). The physical and mechanical properties such as water absorption, thickness swelling, linear expansion, density, weight gained, flexural modulus and strength were tested. Entandrophragma cylindricum ranked highly in mechanical properties at plastic/wood ratio of 1:2.3, and more dimensionally stable at plastic/wood ratio of 1:1. As the wood content increases in the formulations of the composite, the increased in the flexural and decreased in dimensional stability of the composites produced. This observation follows the same trend in all the wood species employed for the production of composites tested. Based on the results, the guidelines information from this study could be used as a basis for WPC manufacture in tropical country like Nigeria.
