Abstract
The invention provides a knitted spacer fabric having a tightly knitted bottom layer, a more loosely knitted upper layer and pile yarns extending across the space between the lower and upper faces. Settable material, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations.
