Wood physics, research needs


The international community of forest products scientists perceives research needs in wood physics in a broad range of subjects. The research needs compiled here are organized into several areas of wood physics and technology, for the purpose of helping individual scientists formulate research projects and programs that are consistent with widely recognized needs.
