Abstract
A method of detecting conversion quality includes the steps of providing an article having a green material and a semiconductor material, processing the green material and the semiconductor material to produce a matrix composite, and detecting a matrix composite conversion quality with the semiconductor material.
Claims21
A method of detecting conversion quality, comprising the steps of:
- providing an article having a green material and a semiconductor material;
- integrating the semiconductor material into the green material to produce a matrix composite;
- detecting a matrix composite conversion quality with the semiconductor material, the detecting step includes applying a voltage to the semiconductor material to obtain a response from the semiconductor material indicative of a matrix composite conversion quality;
- and
- producing a matrix composite component if a sufficient matrix composite conversion quality is detected.
