Abstract
A method for making a pre-impregnated composite material (prepreg) is provided. The prepreg can be cured to form composite parts that have high levels of damage tolerance. The matrix resin includes a thermoplastic particle component that is a blend of particles that have a melting point above the curing temperature and particles that have a melting point at or below the curing temperature.
