Abstract
With an arrangement of two different densities in a fiberboard according to the newly developed Dascanova Technology a significant amount of raw material could be saved. In this part of the study a production possibility of fiberboard with dual density was investigated. The aim of this research is to produce the highest possible difference between densities formed in one press process. Various methods described by different resin systems, additives, moisture contents and modified raw materials were used for this purpose. The highest difference of 80% between two densities was reached by a combination of more input parameters. These influences and a description of the hardening process during one press cycle are presented in detail in this study.
