In the past few centuries, natural wood has been used extensively in the construction of buildings, but it has its limitations. Even after pretreatment, temperature changes such as extreme heat conditions may cause the wood to expand and weaken it.
A team of scientists at the University of Maryland proposed two steps to help natural wood overcome these obstacles because it is the cheapest and most preferred building material in the world.
Their solution involves the partial removal of lignin and hemicellulose from natural wood, followed by hot pressing to fully densify the natural wood and increase its strength by a factor of 10.
Scientists wrote in academic papers published in the journal Natural Science: “Our processing wood has a higher specific strength than most structural metals and alloys, making it a low-cost, high-performance, lightweight material. alternatives. '
