strong as steel and lightweight? must be superdense wood

8 feb 2018 in a bid to put the spark back in this old flame a team of us researchers has developed superdense wood — a highly-compacted wood that's about as strong as steel but much more lightweight. the enviable physical properties of this material can be traced back to its production. it is constructed by boiling regular blocks of wood in a water-based solution of sodium hydroxide (lye) and sodium sulfite. these chemicals remove part of the lignin and hemicellulose in the&nbsp;【Get Price】

mechanical properties of wood - civil and environmental engineering

he fibrous nature of wood strongly influences how it is used. wood is primarily composed of hollow elongate spindle-shaped cells that are arranged parallel to each other along the trunk of a tree. when lumber and other products are cut from the tree the characteristics of these fibrous cells and their arrangement affect such properties as strength and shrinkage as well as the grain pattern of the wood. this chapter briefly describes some elements of wood structure. bark wood&nbsp;【Get Price】
