European co-operation in wood research From native wood to engineered materials : Part 2: densification modification in product development

• Wood  is  a  renewable,  biological  material  used  in  numerous  applications  and  it  is  growing  in  importance  due  to  sustainable  development  efforts.  Wood  also  suffers  from  a  number  of  disadvantages,  were low hardness and abrasive resistance are characteristic for low-density species.  This paper presents state of the art on different wood densification processes as one emerging process technology for increased use  of  low-density  species.  The  presentation  is  based  on  work  by  different  European  research  groups  in  wood  science,  collaborating  in  the  field  mainly  through  different  COST  Actions.  The  main  principles  for  processes are discussed, such as bulk and surface densification, as well as methods for reducing the shape memory  effect  of  densified  wood.  The  main  challenges  for  the  future  are  in  the  field  of  finding  fast  and  environmental  friendly  method  for  elimination  of  the  set-recovery  and  scaling  up  to  profitable  industrial  applications.  To  provide  a  better  understanding  with  this  regard,  some  relevant  applications  of  densified  wood are presented.
