The relationship between thickness swelling and mat structures in robot-formed flakeboard mats under humid conditions with consideration of the density/overlaps in the flakeboard and the absorbed moisture has been studied. Results show a highly correlated linear relationship between thickness swelling and relative moisture content. The relationship between moisture absorption coefficient and the density/ overlaps is also linear.
