COMPOSITES

摘要

Embodiments include methods of forming a composite. The methods can include providing a foam core, wherein the foam core includes a foam having a softening point of 90 °C to 1 10 °C, covering a portion of the foam core with a prepreg, contacting the prepreg that covers the portion of the foam core with a curable composition, and curing the prepreg and the curable composition to form the composite, wherein the prepreg insulates the foam core during the curing so that the foam maintains a temperature that is below the softening point. Embodiments include a composite obtained by curing the prepreg and the curable composition. Embodiments include B-stageable formulation having a resin component and a hardener component.
