Effect of moisture content on mechanical properties, thermal and ...10 Jun 2004 ... Abstract. Mechanical properties and thermal and structural changes of poly(vinyl chloride) (PVC)/wood sawdust composites were assessed with respect to the effect of moisture content, varying from 0.33 to 3.00 % by weight in the composite, for three different wood sawdust contents. The swell ratio and texture characteristics of the composite extrudates were also evaluated. Unique explanations were given to describe changes in the composite properties in terms of ...

Influence of type and concentration of maleic anhydride grafted ...26 Apr 2005 ... Abstract. Surface treatments of natural fibers in polymer-wood composites (PWC) are still one of the most interesting subjects for research among technologists, especially with inclusion of other property modifiers in the composites. This work investigated the effects of incorporating different types and contents of maleic anhydride grafted polypropylene (MAPP) and impact modifiers, as property promoters, on the mechanical properties of PP/wood sawdust composites.

High performance wood composites from highly filled ...18 Nov 2005 ... Highly filled systems prepared by compression molding of Hevea brasiliensis woodflour filled polybenzoxazine composites with high mechanical properties and reduced water uptake has been developed. The effects of percent filler content and particle size of woodflour on the obtained composite's properties were examined. The low melt viscosity of BA-a type polybenzoxazine allows substantial amount of woodflour to be easily incorporated into the composites.

Development of woodsubstituted composites from highly filled ...17 Jan 2007 ... Abstract. Highly filled wood-substituted composites from matrices based on polymer alloys of benzoxazine resin (BA-a) and phenolic novolac resin using Hevea brasiliensis woodflour as a filler were developed. The results reveal that phenolic novolac resin can significantly reduce the curing temperature of the neat benzoxazine resin, thereby minimizing the degradation of woodflour filler during processing. The limiting oxygen indices (LOIs) of all the BP alloys were ...

Flame retardancy, antifungal efficacies, and physicalmechanical ...13 Nov 2016 ... This work aimed to examine flame retardancy, antifungal performance and physicalmechanical properties for silane-treated woodpolymer composites (WPCs) containing zinc borate (ZnB). ZnB with content from 0.0 to 7.0 wt% was added to WPCs, and silane-treated wood contents were varied. The polymers used were poly(vinyl chloride) (PVC) and high-density polyethylene (HDPE). The decay test was performed according to the European standard EN 113.

Three different UV stabilizers, 2-(2H-benzotriazol-2-yl)-4,6-ditertpentylphenol (Tinuvin XT833), 2-(2H-benzotriazol-2-yl)-p-cresol (Tinuvin P), or rutiletitanium dioxide (TiO2) were incorporated into poly(vinyl chloride) (PVC) and wood/PVC (WPVC) composite, and mechanical and physical properties and photostabilities were monitored. The polyene and carbonyl sequences of PVC increased with UV weathering time and with presence of wood flour.

Effect of wood sawdust content on rheological and structural ...21 Oct 2003 ... The composites having sawdust higher than 16.7 wt% showed a benefit of cost savings. 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 decomposition temperature and an increase in polyene sequences, which ...
