Abstract
The invention relates to a process for preparing a fibre-reinforced composite or a fibre-reinforced coating, which comprises impregnating reinforcing fibres with a radiation-curable composition comprising a polymerisable monomer and a polymer which is dissolved or dispersed in the monomer, and exposing the impregnated fibres to radiation to effect curing of the composition.
Claims18
A process for preparing a fiber-reinforced composite rod, for use as a strength member, which comprises:
- (a) pulling continuous reinforcing fibers through a bath containing a radiation-curable composition so as to impregnate the fibers with the composition, wherein the composition comprises a monomer which is polymerizable under the effect of ultraviolet (UV) radiation, a polymer which is dissolved or dispersed in the monomer and a photoinitiator;
- (b) pulling the impregnated fibers through a die downstream of the bath;
- and
- (c) exposing the impregnated fibers to UV radiation to effect polymerization of the monomer thereby producing a fiber reinforced composite.
