Recent progress in modeling bonding performance of wood composites: resin distribution and inter-element bonding

Dai Chunping, . and Yu Changming, . and He Guangbo, . (2006) Recent progress in modeling bonding performance of wood composites: resin distribution and inter-element bonding. [Proceedings Paper]

Bonding of wood composites has been long investigated predominantly using trial and error approaches in the literature. This presentation reports our progress in developing theories and models for resin distribution mat consolidation and product bonding strength. Based on the theories of random coverage processes resin distribution is analytical defined in terms of average and variance of resin coverage. Also a numerical model is developed on a computer to complement the analytical model. Resin distribution on OSB strands is experimentally investigated using an image analysis technique. The analytical and numerical models are validated by close arrangements with each other and with experimental results. Mathematical models and computer models are also developed to predict the contact between wood constituents during the course of mat consolidation. Finally a mathematical model is developed to predict bonding strength between two overlapped wood strands. These models offer a useful approach to further modeling the internal bond strength of strand-based composites.

Abstract

Bonding of wood composites has been long investigated predominantly using trial and error approaches in the literature. This presentation reports our progress in developing theories and models for resin distribution mat consolidation and product bonding strength. Based on the theories of random coverage processes resin distribution is analytical defined in terms of average and variance of resin coverage. Also a numerical model is developed on a computer to complement the analytical model. Resin distribution on OSB strands is experimentally investigated using an image analysis technique. The analytical and numerical models are validated by close arrangements with each other and with experimental results. Mathematical models and computer models are also developed to predict the contact between wood constituents during the course of mat consolidation. Finally a mathematical model is developed to predict bonding strength between two overlapped wood strands. These models offer a useful approach to further modeling the internal bond strength of strand-based composites.
