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 110° 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.
摘要:
A curable epoxy resin composite composition including a reinforcing material and an epoxy resin composition, and a process for preparing a composite from such composition; wherein a combination of at least one alkanolamine and at least one styrenated phenol are present in the epoxy resin composition in a sufficient amount to increase the rate of reaction of the at least one epoxy resin and the at least one alkanolamine curing agent while maintaining the thermal and mechanical properties of the composite upon curing of the epoxy resin composition.
