Woodwork


Woodwork
German scientists say that they have created a new material which contains all of the best qualities of wood, but that is mouldable like plastic. Wood is composed of long cellulose fibres and shorter molecules of "lignin". The cellulose gives the wood strength and the lignin provides stiffness. The new material is made by combining cellulose fibres with lignin and then processing the mixture through a moulding apparatus. This process enables the new material to be moulded to any shape required.
