Abstract
A composite material includes a polymer matrix, a polymerizer, and a plurality of capsules containing a corresponding activator for the polymerizer. The composite material can also include an adhesion promoter, and the polymerizer can be phase separated from the polymer matrix. The composite material can be made by dispersing the polymerizer and capsules into the polymer matrix. These composite materials can exhibit improved environmental stability, and can be used with a wider variety of activators.
