Aucoumea klaineana (angouma, gaboon, or okoumé) is a tree in the family Burseraceae, native to equatorial west Africa in Gabon, the Republic of the Congo, and Rio Muni. It is a medium-sized hardwood tree growing to 30–40 m tall, rarely larger, with a trunk 1-2.5 m diameter above the often large basal buttresses. The tree generally grows in small stands, the roots of the trees intertwined with neighboring trees. In Gabon it is the primary timber species.
It is a weak wood with low decay resistance and moderate dimensional stability. The major use of Gabon is in the manufacture of plywood. It is about 8- 12% lighter than the other main marine plywood Meranti that is commonly used in boatbuilding, but is not as stiff. This is useful when a boat design calls for tight radius bends such as near the bow in a single chine design because of its flexibility. However it does not resist impact damage as well as Meranti and is often sheathed in epoxy resin to increase strength and give more impact and abrasion resistance and to increase water resistance over conventional marine enamel paints. It is often used in sandwich construction using the West (and other similar) epoxy system. Its attractive appearance means that it is often used decoratively as the top surface veneer in panelling and furniture or, in solid form in luxury items such as boxes for cigars or other high value items (e.g. audio equipment).
Gaboon plywood is also used in the French aircraft industry to make light airplanes, such as those built by Avions Robin. It was used extensively to manufacture the Jodel range of aircraft, which are popular throughout Europe but no longer factory-built. However, the wood's open grain, flexibility and light weight make it a popular choice for amateur builders of Jodel aircraft to this day.
