Abstract

A composite material precursor composition includes a matrix precursor, a first plurality of capsules including a liquid polymerizer, an activator, and an accelerant. The liquid polymerizer polymerizes when in contact with the activator, and the accelerant is an accelerant for the polymerization of the liquid polymerizer. The composite material precursor may be used to form a composite material that includes a solid polymer matrix, the first plurality of capsules in the solid polymer matrix, the activator in the solid polymer matrix, and the accelerant in the solid polymer matrix.
