Abstract
A reinforced composite material includes a solid polymer matrix, a reinforcing material in the solid polymer matrix, and a first plurality of capsules. The reinforcing material includes a surface. The capsules are on the surface of the reinforcing material, and include a liquid healing agent. The amount of the healing agent of the capsules is at least 0.01 milligrams per square centimeter of the surface area of the reinforcing material.
