Abstract
Shaped articles made of balsa veneers, balsa chips, balsa strands or balsa strips, which are oriented in the same direction according to their grain direction, and the grain direction of the individual chips deviates by 0° to 30° from the direction of the axis of the grain. The spaces of the adjacent balsa veneers, chips, strands or strips are filled with a, for example foamed, adhesive, the density of which may be the same as or close to the density of the surrounding balsa wood.
