They already contain an amount of the matrix material used to bond them together and to other components during manufacture.

Thermoset polymers are the most widely used matrix material in composite materials.

Composites are often described in terms of their matrix material and reinforcement material.

The matrix material can be selected from almost any metal, polymer or ceramic.

It is also used to free useful materials from matrix materials in which they are embedded, and to concentrate minerals.

This naturally sets a lower limit to the amount of matrix material used.

The matrix material is quasi-organic, neither living nor truly dead.

The larger grains can be sand-to-gravel-sized, and matrix materials make up more than 15% of the rock by volume.

Experiments were held with different fuel elements and matrix materials.
