Title: YOUNG MODULUS OF HEAT-TREATED CARBONS - A THEORY FOR NONGRAPHITIZING CARBONS
Author: EMMERICH, FG
LUENGO, CA
Abstract: An expression to calculate the Young's modulus of nongraphitizing carbons as a function of heat treatment temperature (HTT) is developed. A microscopic model involving parameters of the carbon granular structure is used, where the cross-linkings between microcrystallites play a fundamental role. The theoretical expression is applied to the endocarp of babassu coconut heat treated from 400-degrees-C up to 2200-degrees-C; it explains satisfactorily the behaviour of the modulus with HTT, including the maximum that generally occurs around 1100-degrees-C HTT.
