Abstract
Abstract A composite material in substantially two-dimensional or planar or sheet form, which material comprises: (a) at least one layer of a fiber-like or fabric material; and (b) at least one layer of a composition which comprises a polymer, a curable resin and an addition-polymerizable initiator composition. The composite material may be cured to form a prosthetic device, e.g. a rib cage.
