Abstract
A method of making a fiber reinforced composite includes: infiltrating a preform having a perimeter with an electrophoretic gel; adding nanoparticles to wells located in the electrophoretic gel outside the preform perimeter; introducing the nanoparticles to the preform using gel electrophoresis; removing the electrophoretic gel to result in a preform having embedded nanoparticles; and infiltrating the preform having embedded nanoparticles with a matrix material or a matrix material precursor.
