Abstract
The invention relates to a method for curing of a composite material. The method involves applying heat to only a first region of said composite material, such that said first region is heated to a temperature above the cure onset temperature of said curable resin, thus initiating curing of said curable resin in said first region; and maintaining the composite material in an insulated state, such that the curing of said curable resin spreads to regions of the composite material outside of said first region.
Claims14
A method for curing of a composite material, said method comprising:
- a. providing a composite material comprising at least one layer of fibrous material and curable resin;
- b. applying heat to at least one first region of said composite material, such that said first region is heated to a temperature above the cure onset temperature of said curable resin, thus curing said curable resin in said first region;
- c. maintaining the composite material in an insulated state, such that the heat from the exothermic curing reaction in said first region acts to heat at least one uncured second region of the composite material to a temperature above the cure onset temperature of said curable resin in said at least one second region, such that the curing of said curable resin spreads from cured to uncured regions of the composite material at a temperature above the cure onset temperature.
