Abstract: By treating eucalyptus veneer with different amounts of silane coupling agent, we investigated the effect of the treatments on the physical and mechanical performance of as-obtained eucalyptus veneer/polyvinyl chloride (PVC) film composites by hot-cold pressing crafts. Interfacial compatibility of the composites was analyzed using a scanning electronic microscope (SEM). The best treating effect was observed in the composites coupled with 1% silane agent, which resulted in an increase in bonding strength and water resistance. The treatment with 3% silane coupling agent caused the increase in MOE and MOR. After the treatment with silane coupling agent, the interfacial compatibility of the veneer composites was improved.
