Bionic hollow fibre with self repairing effect

The German Institute for (ITCF) Textile Chemistry and Chemical Fibres, Denkendorf, has performed research work on bionic hollow fibres with a mono nucleus for self repairing composites such as carbon fibre matrix-composite

The human corps is capable of healing itself and such bionic materials should be able to repair its original characteristics. New research has been proving that micro-ruptures in polymer matrices of composites can be immediately closed by the incorporated monomer systems. For that purpose micro capsules are filled in a complex process with monomer and homogenously mixed with the entire polymer matrices. When micro-ruptures occur, these capsules will be locally destroyed and the monomer liquid is networking with the help of a special catalyst with the matrices thus closing the rupture at least up the end of the life cycle of the product.
