University of Maryland Develops Superwood with Strength Comparable to Steel and Aluminum
Researchers at the University of Maryland have created a new material called superwood, which boasts strength comparable to steel and aluminum by modifying the internal structure of natural wood. This innovative material, produced through a two-step process, demonstrates significant compressive and bending strength while remaining dimensionally stable and environmentally friendly, reducing carbon emissions by up to 90%. InventWood, a startup, is now commercializing superwood for applications in construction, transportation, and defense.

Researchers at the University of Maryland have developed a new material called superwood, which surpasses conventional wood in strength and competes with steel and aluminum. Superwood is created by altering the internal structure of natural wood to enhance its strength, reduce weight, and improve durability.
The production method involves a two-step process: chemical softening followed by compression, resulting in a dense and aligned cellular structure. Tests show compressive strength exceeding 160 MPa and bending strength over 330 MPa, with some species demonstrating up to five times increased tensile strength.
The material remains dimensionally stable under high humidity and has achieved a Class A fire resistance rating. InventWood, a startup commercializing the technology, has initiated small-scale production and is collaborating with construction, transportation, and defense sectors. The process reduces carbon emissions by up to 90% compared to steel production and utilizes renewable biomass.
