Jun 23, 2016 . More than that, its reduction indicates that the addition of wood sawdust into NR composites had a negative effect upon the ductility because of the appearance of a restriction in the molecular chains movement . In addition, the striking forces between the filler and the polymer molecules, had led

Oct 21, 2003 . The decreases in the mechanical properties of PVC with sawdust are explained in association with the presence of moisture, interfacial defects between fibre and polymer, and fibre dispersions in the PVC matrix. Thermal degradations of PVC in PVC/sawdust composites were evidenced by a decrease in..
Nov 23, 2013 . The wood plastic composites (WPCs) were made with a thickness of 6 mm after mixing the saw dust and PET in a rotary type blender followed by flat press process. Physical i.e., density, moisture content . It is a long-chain polymer (C10H8O4)n belongs to the polyesters family. It shows both amorphous..
The mechanical properties of compression-moulded polystyrenes filled with sawdust wood residue of softwood and hardwood species have been investigated. The tensile modulus at 0.1% strain and the tensile strength, elongation and energy at the yield point are reported. The suitability of sawdust wood residue as a filler..
In this study, composites were made with wood sawdust residues and a polyolefin. Experiments were carried out in order to analyze different parameters for processing the composites. The parameters analyzed were the sawdust/polymer ratio and the type of coupling agent. The sawdust and the polymer were mixed
Abstract. The paper presents the results of the research dedicated to synthesis and characterization of some new, ecological composite materials based on an acrylic copolymer, lignin derivative iron and chromium lignosulfonate and Salix wood sawdust. The FT-IR analysis put into evidence the complex interactions, by..

of wood/polymer composites, however, very limited work has been done on the effect of wood dust types on friction and wear characteristics of polymer composites. Against this background, . and filler loading on mechani cal properties of the acacia saw dust unsaturated polyester resin (UPR) composite based on re
In this research, wood polymer composite (WPC) were produced by using the combination of waste sawdust (Cengal and mixed sawdust), unsaturated polyester resin and a catalyst as the curing agent. The WPCs were produced at four levels of sawdust loading (5 wt% - 20 wt %) with resin and 3% of catalyst added to study..
