A method of producing a dehydrated hydrogel comprises dispersing fibres into an aqueous solution of a hydrogel precursor material incorporating a plasticiser, the fibres incorporating cations which are capable of cross-linking said precursor material to form a hydrogel, and freeze drying the mixture thus produced to provide a dehydrated hydrogel which incorporates said fibres, the dehydrated hydrogel being cross-linked by said cations.
