Researchers from KTH Royal Institute of Technology and Chalmers University of Technology conducting a research at the Wallenberg Wood Science Centre are changing the way we look at the forests. The forest industry has been very important for Sweden’s economy. This is why there are a lot of efforts to develop new techniques and methods in which the wood from these forests can be utilized. At the same time, research is conducted to create new products from wood.
The researchers have been trying to find new avenues in which wood can be used and they are prospecting inside wood to find something that was not used before. One of the projects involves finding ways in which tiny fibers called nanocellulose that are extracted out of wood can be used to build materials that can be stronger than Kevlar.
One of the most important reasons for using wood fiber is the fact that it is renewable and it is beneficial for the carbon dioxide balance. The nano cellulose material is used in different ways to form materials. The researchers have used the material and combined it with other substances to form a fiber which was used by them to create a helmet. The helmet is strong and proves the application of nano cellulose.
In another part of the project, the nano cellulose is passed through salt water in a way that the tiny fibers connect with each other to form a strong thread. Researchers are contemplating the use of this thread in bullet proof vests, building insulation, environment friendly packaging and in cars.
While the applications of nano-cellulose are yet to be fully explored, it has been established that it can be used for creating a material that can be as strong as Kevlar.
