✦ Synopsis

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 ofbabassu coconut heat treated from 400°C up to 2200°C; it explains satisfactorily the behaviour of the modulus with HTT, including the maximum that generally occurs around 1100°C HTT.

A microscopic cross-linking model has been applied to calculate the Young's modulus as a function of heat-treatment temperature (HTT) of petroleum coke (a graphitizable carbon) and Akabira coal (a non-graphitizable carbon). This model is an extension of a previous model for non-graphitizable carbons
