New strengthening technique could boost wood’s use in building: Research

Russian researchers have invented a new coating technique that strengthens wood tissue, a breakthrough that can expand wood’s use in electrical transmission towers, columns, building construction components such as trusses and frames, bridges, and lamp posts.

By impregnating the wood with an epoxy-based coating and then covering it with a grid of carbon fiber-reinforced plastic and finally spreading a protective coating called “EpoxyPAN”, wood is converted into a hybrid wood- polymer nanocomposite with advanced properties.

The combination of the base coating, carbon plastic, and protective material makes the wood more durable and water- and fire-resistant. It is also 40% lighter than metal alternatives and 10% cheaper. 

“The new materials by far exceeds raw wood in durability and longevity with the best properties of wood remaining untouched,” Prof Andrey Ponomarev and PhD student Alexander Rassochin from the Institute of Engineering and Building at Peter the Great Saint Petersburg Polytechnic University (SPbPU), said.
