%X <span style=\"font-family:&quot;\">We produced Wood-Polymer Composites
(WPCs) with phenolic resin (PR) filled with saw dust (SD) and rice husks (RH) in
a PR:fillerratio of 60:40 wt.%. RH and SD</span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">were grinded and sieved into
particles &lt;160</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">¦Ìm.</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">The aim of this research work
was to evaluate sawdust and rice husks as fillers for sustainable phenolic resin
based WPCs. Therefore, we investigated the thermal stability of PR/RH and PR/SD
WPCs</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">then</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">we studied and</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">compared the tensile, flexural
properties of PR/SD and PR/RH WPCs samples, as well as their</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">dimensional stability after water
absorption test. Furthermore, through ultraviolet light exposure, we evaluated the
effects of photo-oxidation on the water stability and mechanical properties of PR/RH
and PR/SD WPCs samples compared to unexposed ones.</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">PR filled with SD presented better
mechanical properties compared to PR/RH WPCs samples. However, PR/RH WPCs showed
good mechanical properties, and better thermal resistance and better water repulsion
capabilities compared to PR/SD WPCs samples.</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">Although, long time UV exposure
ended up lowering considerably the mechanical properties and water resistance of
PR/SD and PR/RH WPCs, both RH and SD offer great added value as fillers for PR based
WPCs; SD having better interactions with PR matrix compared to RH.</span></span></span>
