“…It has been suggested, that water can be transferred into a composite by means of diffusion through microvoids in the polymeric phase or through spaces on the interface between the filler and the matrix, which could act as capillaries [6,27,28]. An increase in water absorption can be observed even if the fibers are not highly hydrophilic [28]. In case of a lignocellulosic filler, the composite absorbs even more moisture, as it was found in our research.…”

“…In most of the cases μ values of the "wet" samples are higher than the ones of the "dry" samples. Papers indicate [15,23,28] that water acts as a lubricant and can drastically lower the coefficient of friction. Surprisingly, these findings does not disagree with the results of the test.…”

“…Nevertheless, the relationship between filler content (either a synthetic or an organic one) and friction of a composite is not fully understood. An addition of fibers can decrease as well as increase the coefficient of friction [20,28,38] and the resulting effect is believed to be determined with the interactions between the phases [38]. It is considered that poor interaction between filler and matrix leads to an increase of the coefficient of friction [28,38].…”

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

Linseed cake (LC), a byproduct of linseed oil extraction, is used as a functional filler for production of biodegradable composites. To determine the influence of residual linseed crude oil contained in lignocellulosic filler on the properties of the poly(lactic acid) (PLA)-based composites with 5-30% filler content, two types of LC were analyzed: a defatted and an unmodified one. Complex analysis of the composites' properties change was conducted in relation to their structure modification caused by the addition of a waste filler. It was found that the addition of LC resulted in simultaneous plasticization and improved crystallization of PLA. Lignocellulosic particles and crude linseed oil contained in the LC powder provided a modifying effect, influencing the level of crystallinity and mechanical and thermomechanical properties. Using LC may thus overcome one of the main drawbacks of PLA, which is brittleness and low crystallinity.

Influences of (3‐aminopropyl)triethoxysilane on the tribological behaviors of basalt fiber/acrylonitrile‐butadiene rubber composites under dry friction and water‐lubricated conditions

The weak interaction between the basalt fiber (BF) and acrylonitrile‐butadiene rubber (NBR) weakens the BFs' effects on improving the tribological performances of the NBR composites. To solve this problem, (3‐aminopropyl)triethoxysilane (APTES) was introduced via mixing into the matrix or grafting on the BF surface, respectively. The characteristics, mechanical, and tribological properties of the composites were evaluated, and the effects of the APTES and its introduction methods on the tribological properties were the main focus. The APTES mixed in the rubber matrix decreased the friction coefficient (COF) of the NBR‐based composites under both dry friction and water‐lubricated conditions. Especially, the APTES hydrolysis under water‐lubricated condition was conducive to the formation of the water film and thus dramatically decreased the COF. The COF of the BF0‐A3 and the BF12‐A3 were 51% and 30% lower than that of the BF0‐A0 and the BF12‐A0 under water lubrication, respectively. The APTES grafted on the BF surface increased the wear resistance of the BF/NBR composites attributed to the improvement of the interaction between the BFs and the NBR matrix. © 2019 Wiley Periodicals, Inc.
