In this video, you learn about large-particle and dispersion-strengthened composites which are the two sub-classifications of particle-reinforced composites. The distinction between these is based on the reinforcement or strengthening mechanism. 
For dispersion-strengthened composites, particles are normally much smaller, with diameters between 0.01 and 0.1 μm (10 and 100 nm). 
WC: tungsten carbide – ceramic
Biding between phases: dispersion (atoms), Large (interaction between phases on the macro-level)
In a Particle-reinforced Composite, the volume fraction of the two phases influences the behavior; mechanical properties are enhanced with increasing particulate content. Two mathematical expressions have been formulated for the dependence of the elastic modulus on the volume fraction of the constituent phases for a two-phase composite. 
The modulus of elasticity versus volume percent tungsten for a composite of tungsten particles dispersed within a copper matrix is explained in this video. Upper and lower bounds are according to Equations 16.1and 16.2 from the textbook, respectively; experimental data points are also included and explained in the video.
In the expressions presented, E and V denote the elastic modulus and volume fraction, respectively, and the subscripts c, m, and p represent composite, matrix, and particulate phases, respectively.
