For this purpose 3-layer particleboards were produced with varying shares of Kraft scrap paper pulp in the core. Experimental boards were manufactured applying 0, 10, 15, 25, 50 and 75% substitution of wood chips with Kraft paper pulp. Analyses were conducted to determine physico-mechanical properties of boards, i.e. bending strength, modulus of elasticity, internal bond before and after the boiling test and swelling in thickness after 24 soaking in water. Based on recorded testing results it was stated that moisture resistant composite boards manufactured with a 25% substitution of wood chips with Kraft paper pulp meet the requirements of the EN 312 standard for boards used in humid conditions in terms of their strength and moisture resistance specified in the internal bond after the boiling test. 2018 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48557615001 https://www.redalyc.org/journal/485/48557615001/ https://www.redalyc.org/journal/485/48557615001/html/ https://www.redalyc.org/journal/485/48557615001/48557615001.epub https://www.redalyc.org/journal/485/48557615001/movil en http://www.redalyc.org/revista.oa?id=485 Maderas.
