抄録

The biological resistance of wood plastic composites using methyl-methacrylate and phenolic-resin was evaluated with an emphasis on the structural characteristics of the cell wall after exposure to fungal attack. Differences in the polymer deposition in the wood cellular structure due to combination with plastic exhibited the specific patterns of cell wall erosion caused by decay fungi. Scanning electron microscopic observations confirmed that the smallmolecular weight phenol-formaldehyde (PF) resin easily penetrated the wood and led to the deposit of polymers within the cell walls, resulting in a high resistance to decay. In contrast, the limited levels of penetration of the large-molecular weight PF-resin and the methacrylate resin led to formation of polymer bodies in the cell lumens or the partial surface coatings which contributed little to the decay resistance.
