Changing from damage prevention to damage management, thereby allowing some cracks in a structure as long as the cracks self-repair over time, is the basic concept behind self-healing materials. Following natures possibilities in transport using wood fibres, this paper describes how natural wood fibres can be used for self-healing. Starting from a concept view point, it is shown how fibres can control crack growth, is self-healing demonstrated when water sources from outside are available and are preliminary steps given to use wood fibres as initial water source suppliers.
