This paper studies the effect of panel moisture content (MC) on the physico-mechanical properties of medium density fiberboards (MDF). Several commercial MDF boards produced in Europe were stored at room temperature and relative humidity (RH) for 9 weeks (approx. range 15\u201320 \u00b0C and 50\u201385% RH). Every week, a strip of each MDF board was cut out, divided into 5 \u00d7 5 cm test pieces and its internal bond strength (IB) was measured. A strong influence of MDF moisture content on internal bond strength was observed and therefore IB test pieces were stored in a climatic chamber (either at 20 \u00b0C, 55% RH and at 20 \u00b0C, 70% RH). A decreasing linear relation was established between IB and MC. It was found that this effect is reversible: after drying, internal bond strength rises again (following a slight hysteresis). This work reinforces the importance of conditioned storage before board properties analysis, as described in European Standard EN 319.<\/jats:p>","DOI":"10.3390\/polym13010114","type":"journal-article","created":{"date-parts":[[2020,12,30]],"date-time":"2020-12-30T20:13:41Z","timestamp":1609359221000},"page":"114","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Effect of Panel Moisture Content on Internal Bond Strength and Thickness Swelling of Medium Density Fiberboard"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3881-1450","authenticated-orcid":false,"given":"Roberto","family":"Magalh\u00e3es","sequence":"first","affiliation":[{"name":"EuroResinas\u2014Ind\u00fastrias Qu\u00edmicas, 7520-195 Sines, Portugal"}]},{"given":"Beatriz","family":"Nogueira","sequence":"additional","affiliation":[{"name":"EuroResinas\u2014Ind\u00fastrias Qu\u00edmicas, 7520-195 Sines, Portugal"}]},{"given":"Samaritana","family":"Costa","sequence":"additional","affiliation":[{"name":"EuroResinas\u2014Ind\u00fastrias Qu\u00edmicas, 7520-195 Sines, Portugal"}]},{"given":"N\u00e1dia","family":"Paiva","sequence":"additional","affiliation":[{"name":"EuroResinas\u2014Ind\u00fastrias Qu\u00edmicas, 7520-195 Sines, Portugal"}]},{"given":"Jo\u00e3o M.","family":"Ferra","sequence":"additional","affiliation":[{"name":"EuroResinas\u2014Ind\u00fastrias Qu\u00edmicas, 7520-195 Sines, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4447-4473","authenticated-orcid":false,"given":"Fern\u00e3o D.","family":"Magalh\u00e3es","sequence":"additional","affiliation":[{"name":"LEPABE\u2014Laboratory for Process Engineering, Environment, Biotechnology and Energy, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"given":"Jorge","family":"Martins","sequence":"additional","affiliation":[{"name":"LEPABE\u2014Laboratory for Process Engineering, Environment, Biotechnology and Energy, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"DEMad\u2014Departamento da Engenharia de Madeiras IPV, 3504-510 Viseu, Portugal"}]},{"given":"Luisa H.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"LEPABE\u2014Laboratory for Process Engineering, Environment, Biotechnology and Energy, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"DEMad\u2014Departamento da Engenharia de Madeiras IPV, 3504-510 Viseu, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,30]]},"reference":[{"key":"ref_1","unstructured":"EN 622\u20135 (2009).
