Resumo: Saturating kraft paper is commonly used for laminate production through phenolic resin impregnation followed by insitu thermal resin curing. The laminate mechanical resistance and also its service performance depend on extent of resin curing. Nowadays,the conventional methods employed to quality control these products are time consuming, destructive, expensive, and, most of the time,supply only qualitative data. Using diverse temperature and time of treatments the extent of curing can be tuned to any values between 0 and1. Kraft impregnating sheet production is a valuable niche market that has relied on empirical modeling for many years to improve quality andcustomer satisfaction. There are a number of proprietary technologies for their production, but the basic manufacturing motif is to form a woodpulp-based sheet that is then impregnated with polymer-based resin and the whole system is then heat cured. As far as we know, there havebeen very few systematic studies done to examine the process, let alone improve the state of the art in this market. However, there are a lot ofdata and patents that examine its assembly for decorative purposes of at least three plies of paper with at least one impregnated with phenolicresin; yet, the focus of a lot of past work concerns the gloss, pigmentation, and texture of the outmost ply.
