Abstract
Uncured composite structures, cured composite structures, and methods of curing uncured composite structures are disclosed herein. The uncured composite structures include a structural layer that includes an uncured structural resin and a surface layer that includes an uncured surface resin. The cured composite structures include a cured structural layer that includes a cured structural resin, a cured surface layer that includes a cured surface resin, and an interface region between the cured surface layer and the cured structural layer. The methods include initially heating the uncured composite structure to an initial temperature to generate a partially cured composite structure. The initially heating is sufficient to gel the uncured surface resin but insufficient to gel the uncured structural resin. The methods also include subsequently heating the partially cured composite structure to a final cure temperature, which is greater than the initial temperature, to generate the cured composite structure.
