particle reinforced composites: A close-up image of a particle reinforced composite sample. The Matrix (metal or polymer) must be visible, containing fine particles of contrasting color (as silicon carbide particles in a silver aluminum matrix). the image may show a cross section, highlighting how the particles are evenly dispersed in the matrix, with a caption stating "particle reinforced composite".
