The aim of this work was to manufacture strand and shaving particleboards from Schizolobium parahyba and Erytrina verna and their combinations. The parameters of manufacture were: nominal density 0,65 g/cm³, press temperature 180 ºC, pressing time 14 minutes, resin content 8% (phenol-formaldehyde), particle moisture content 5% (dry weight basis). The best results of static bending tests were found when guapuruvu pure and/or in the face layer was used, although the majority of the treatments presented superior values to when to campared the Canadian Standard (CSA O437-0, 1993). In relation to internal band, 50% of the treatments presented larger values than established by the Canadian Standard. The values of water absorption and thickness swelling were considered high for all the treatments, having to consider that paraffin was not used during board manufacturing.
