Resin-treated, laminated, compressed wood

This technical publication, authored by Alfred J. Stamm and issued by the U.S. Department of Agriculture’s Forest Products Laboratory in 1941, was a product of urgent wartime research. As the United States moved toward full industrial mobilization for World War II, the Forest Products Laboratory focused on developing 'compreg'—a high-density, resin-treated, compressed wood—to serve as a lightweight, durable alternative to scarce aluminum and steel in aircraft components and propellers.

Alfred J. Stamm, a prominent chemist at the laboratory, documented the complex chemical stabilization processes required to imbue wood with properties like high dimensional stability and superior strength. The design of this document reflects its nature as a pragmatic engineering manual, intended to disseminate critical material science data to industrial manufacturers and military engineers who were tasked with rapidly scaling production of military equipment under emergency conditions.
