ROOM TEMPERATURE STRENGTH OF PYROLYTIC GRAPHITE AS AFFECTED BY MICROSTRUCTURE AND BORON CONTENT

Abstract

The strengths of pyrolytic graphites possessing four varieties of microstructure ranging from coarse-coned singularly nucleated to fine-coned continuously nucleated were examined. The fine-coned structure gave substantially higher strengths. Boron-doped pyrolytic graphite with percentages of boron varying from 0.25 to 3.3% were evaluated in terms of their modulus and flexural strength. The higher boron content material (1 to 3.3% B) achieved strengths as much as fifty percent greater than the undoped material.
