Abstract [en]

The decay resistance of fully bio-derived wood plastic composites, WPCs, was tested in bothlaboratory and field tests. The laboratory tests were performed according to modified versionsof AWPA E10 (soil-block test) and ENV 807 (tests in three un-sterile soils) and the field testsaccording to EN 252 (stakes in ground) and EN 275 (resistance to marine borers). The WPCmaterials for laboratory tests were injection molded test specimens with 50% modified woodparticles and 50% cellulose ester (CAP) or poly-lactic acid (PLA) content. The field testspecimens were taken from larger extruded decking board profiles with 60% wood contentand 40% CAP. 60/40-mix (wt/wt) for CAP corresponds to the same volumetric compositionas 70/30-mix (wt/wt) with polypropylene as matrix that was presented in Part 1 and 2.In all laboratory tests the control WPCs performed much better than the pine sapwood controlblocks. The WPCs from modified wood performed better than the control WPC and WPCsfrom acetylated wood performed best with no detectable decay whatsoever.In the field stake test, the WPC from unmodified wood were slightly decayed whereas theWPCs from modified wood were sound. In the marine field test the WPC from unmodifiedwood were severely attacked by shipworm (Teredo navalis), whereas the WPCs frommodified wood were sound.
