Influence of Water on Tribological Properties of Wood-Polymer Composites

Abstract

A B S T R A C TUtilization of ecological materials for appliances and products is one of the ways to achieve the goal of sustainability. Wood-polymer composites as a cheap, lightweight, durable and esthetic material has gained attention of scientists, engineers and consumers alike. Different kinds of polymeric matrices, plants used as the fillers, chemical of physical modifiers and processing technologies have already been widely studied. Nonetheless, surprisingly few information on WoodPolymer Composites' tribology can be found. This paper is an attempt to fill this gap. Polypropylene-and poly(lactic acid)-based composites with varying wood flour content have been analyzed. The Brinell's hardness and coefficient of friction of the samples have been determined. In order to evaluate the influence of the moisture content on the tribological and mechanical properties of the composites, the samples have also been aged in water. The investigation revealed that polymeric composites filled with wood flour can present favorable coefficient of friction, compared to the neat resins. The results of our study can establish a good starting point for further investigation. K E Y W O R D SWood-Polymer Composites tribology, hardness water uptake

Wear and Water Absorption Behaviour of Banana and Sisal Hybrid Fiber Polymer Composites

“…The effect of water asorption on hybrid composite fibers in accordance with ASTM D570 with specimen size 12X12X40 mm 3 . Water absorption tests were conducted by measuring the composite specimen in distilled water in beaker at room temperatiure for different tme durations as shown in Fig.…”

“…The mould box is prepared of mild steel with dimension of volume 300 X 300 X 25 mm 3 as shown in Fig. 1.…”

“…The natural fibers are renewable resources now-a-days used by researchers and many industries. Natural fibers like banana, jute, hemp, sisal etc, have good mechanical, physical and thermal properties [2][3]. By use of hybrid mixture, that is mixing of two or more fibers in one makes the composite advantages altogether, with proper composition of reinforcement and matrix [4].…”

Polypropylene-based composites reinforced with waste tropic wood flours: Determination of accelerated weathering resistance, tribological, and thermal properties

“…Furthermore, in another study, three different liquid solutions were impregnated into wood, and their wear properties were examined (Hamdan et al 2010). Even fewer publications have been dedicated to the study of tribological properties of thermoplastic polymers and their composites incorporating natural fillers, including materials such as polyoxymethylene (Li et al 2008;Xiang et al 2012), polyethylene (Brostow et al 2016;Yang et al 2019;Al-Maqdasi et al 2022), polyvinyl chloride (Jiang et al 2017;, polypropylene (Aurrekoetxea et al 2008;Bajpai et al 2012;Mysiukiewicz and Sterzyński 2017;Ibrahim et al 2019;Mazzanti et al 2021), and polylactic acid (Mysiukiewicz and Sterzyński 2017). Despite the limited number of studies on the subject, a previous investigation indicated that the addition of wood flour reduced the CoF compared to the neat polymer (Aurrekoetxea et al 2008).…”

Insights into Compatibilization of Poly(ε-caprolactone)-based Biocomposites with Diisocyanates as Modifiers of Cellulose Fillers

“…Research works associated with the wood polymer composites (WPCs) can be divided into two main trends -decreasing materials' costs and enhancement of their properties (Mysiukiewicz and Sterzyński, 2017). The first trend is realized by searching for new lignocellulosic fillers from different kinds of agriculture wastes or by applying recycled polymers as matrices (Lewandowski et al, 2016).…”
