Some Correlated Influencing Factors of Bending Strength within Chipboard Technology

摘要

The article presents some aspects referring to static bending strength and its influencing factors. It is an exhaustive study of all influencing factors but it only details the more important and known of these. Only three wooden species are used, namely beech (Fagus silvatica L), spruce-fir (Picea abies Karst) and poplar (Populus tremula L), for obtaining chipboard. Main factors which are considered that they influence the bending strength are: wooden specie, chip thickness, specific surface of chips, percentage of resin, specifical consumption of adhesive and board density. Finally, based on many rigorous experiments, diagrams for the grouped influence of some correlated factors, were realized.
