Porosity is the volume fraction of void space in a solid.

The model also predicts a longer burnout time for a larger particle volume fraction.

For smaller volume fractions, the colloid remains in its liquid state.

A higher fiber volume fraction typically results in better mechanical properties of the composite.

It is difficult to control the fibre volume fraction as well as the thickness.

For a given volume fraction the damage accumulation rate increased with matrix strength and particle size.

The is defined as the volume fraction of grains with a certain orientation .

The temperature, concentration of solute, and solid phase volume fraction are found.

Computations based on volume fractions do not allow to eliminate this ambiguity.

In practice, it's hard to achieve a volume fraction greater than 0.7 and this must be regarded as the realistic limit for commercial materials.

This equation is applicable for suspensions having a low volume fraction of particles.

Both steel and synthetic fibers at variable volume fractions were investigated.

Ferrite volume fraction and hardness were apparently of secondary importance.

This method is preferred as a non-destructive approach to determining fiber volume fraction.

That way, the soft matrix material occupies the largest volume fraction while being close to the hard particles.

Normally the process is capable of producing composites with a fiber volume fraction between 40-50%.

Additionally, the volume fraction of the γ' precipitates increased to about 50-70%.

Mechanical and functional properties of high volume fraction metal matrix composites.

Given the fiber volume fraction, the theoretical elastic properties of a composite can be determined.

Relative surface and volume fractions are chemical constants, which must be known for all chemicals.

For disks and plates, these are effective volumes and volume fractions.

The effects of manufacturing deviations from the nominal fibre volume fraction can be uniquely included.

The volume fraction of these microscopic pores had to be less than 1% for high-quality optical transmission.

We can now introduce a free volume fraction f and substitute in equation (12.13)

Efficiency is affected by aspect ratio, geometry, and volume fraction of the nanoparticles.
