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

Claim 1
Independent Claim
53 words
A composite material in substantially two-dimensional or planar or sheet form, useful in the preparation of a prosthesis, which material comprises: (a) at least one layer of a fibre-like or fabric material; and (b) at least one layer of a composition which comprises a polymer, a curable resin and an addition-polymerisable initiator composition.
Claim 2
Dependent Claim
53 words
A composite material in substantially two-dimensional or planar or sheet form, useful in the preparation of a prosthesis, which material comprises: (a) at least one layer of a fibre-like or fabric material; and (b) at least one layer of a composition which comprises a polymer, a curable resin and an addition-polymerisable initiator composition.
Claim 3
Dependent Claim
17 words
A composite material as claimed in Claim 1 wherein the addition-polymerisable initiator composition is a photo-initiator composition.
Claim 4
Dependent Claim

Claim 10
Dependent Claim
20 words
A composite material as claimed in Claim 7 wherein the curable resin further comprises a low viscosity addition-polymerisable reactive diluent.
Claim 11
Dependent Claim
21 words
A composite material as claimed in Claim 2 wherein the fibre-like material and the composition have substantially the same refractive indices.
Claim 12
Dependent Claim
18 words
A composite material as claimed in Claim 3 wherein the photo-initiator composition comprises an alpha-diketone and an amine.
Claim 13
Dependent Claim
33 words
A prosthetic device comprising a plurality of superimposed layer each of which comprises a photo-cured composition as defined in Claim 2 interwoven by one or more layers of a fibre-like or fabric material.
Claim 14
Dependent Claim
17 words
