Impact of (Wood Particles (Reed) / Polypropylene) Composites on the Physical and Structural Properties

Abstract

The creation of polypropylene resin/wood particle (reed) composites and the investigation of the impact of incorporating natural material residues on the composite's structural and physical characteristics are the main objectives of the current study. The composite of polypropylene resin and wood particles (reed) was created by extrusion with a weight fraction of 30% and treated with a sodium chloride solution (0.5). Bulk density and absorbance rate are among the physical and structural characteristics that are examined for (pure p.p.), (p.p. + w), (p.p. + w + silan coupling agent), (p.p. + w + Mgo), and (p.p. + w + Zn(C18H35O2)2. The results show that adding wood particles, silane coupling agent, magnesium oxide, and zinc stearate increased the bulk density for all samples. The composite with the highest bulk density rate was the (pp + w + MgO) composite. The results of the absorbance test, which involved immersing each composite in distilled water and the chemical solution, are shown. When comparing the samples before and after immersion, the weight gain of the latter is increasing. All samples were examined using Atomic Force Microscopy (AFM). The topographical image makes it clear that the polypropylene composite reinforced with wood particles had a high roughness value. These findings highlight the qualities of plastic wood composites, which are thought to be stronger and more durable than natural wood.
