The composite processing was carried out in a twin screw extruder. Due to the largeamount of solid charge, adaptation of the equipment was necessary. Wood polymer com-posites (WPCs) with 60, 65 and 70% wood residue were obtained. In order to use compositesin applications such as profiles for application on floors, an analysis of the fatigue strengthof the composites was performed, as well as the water absorption capacity. The effect ofultra violet (UV) radiation on the surface of the composites was also evaluated using sim-ulation in a degradation chamber. There was a significant increase in the stiffness of thecomposites and a reduction in flexural strength. Due to the large amount of load, formationof agglomerates was observed, which reduced the impact resistance. In spite of the use ofcompatibilizers, it was observed a weak adhesion between the phases, which impaired inthe number of cycles under fatigue. When subjected to UV-degradation, the materials exhib-ited a small reduction in tensile strength. In general, the results indicate that the developedWPCs, considering applications in floors, presented some suitable properties such as rigid-ity and flexural strength, however, the processing conditions must be adequate for greaterinteraction between the phases.engAttribution-NonCommercial-NoDerivs 4.0 Internationalhttps://creativecommons.org/licenses/by-nc-nd/4.0/WPC compositesWood residuemechanical propertieswaste remediationinfo:eu-repo/semantics/article10.1016/j.jmrt.2020.06.073info:eu-repo/semantics/openAccess
