Wood is a porous and fibrous structural tissue found in the stems and roots of trees. It is soft in nature and a break easily. But a imagine a wood that is as strong as titanium alloy. It is 10 times hard than its actual nature. Is it possible? Let’s acknowledge ourselves with this new technology.
This technology is given by the University of Maryland, Engeeniers who is working on this project found a way that makes wood 10 times stronger and tougher than its natural properties. It is as hard as many titanium alloys. James Clark School of Engineering and the leader of the team working on this project and tell us about properties of this wood.
Key features of This wood
- As strong as steel and titanium.
- This wood is durable.
- We also compare it with carbon fibre
- Cheaper than all these alloys
- 6 times lighter than steel.
- It takes 10 times more energy to fracture than natural wood.
Researchers said ‘Softwoods like pine or balsa, which grow fast and are more environmentally friendly, could replace slower-growing but denser woods like teak in furniture or buildings’. They use these wood in making this tough wood.
How this kind of wood created?
The most outstanding thing researchers see in the wood is the existence of a limiting concentration of lignin which is a glue between wood cells. Lignin is a complex organic polymer deposited in the cell walls of many plants, making them rigid and woody. To maximize the mechanical performance of the densified wood. Too little or too much removal of lignin, lower the strength compared to a maximum value achieved at intermediate. This reveals the subtle balance between hydrogen bonding and the adhesion imparted by such polyphenolic compound. (Phenolic compounds are Hydrocarbons in which one or more hydrogen atoms are replaced by hydroxy group (-OH) are named as alcohols and phenols). This is the fact that wood densification leads to both, increased strength and toughness. This properties of wood lead us to make this kind of wood.
This kind of wood could be used in cars, aeroplanes, buildings – any application where steel is used,
