Material Response Studies (MARS II). Volume 2: High Heating Rate Response of Two Materials from 72 deg F to 6000 deg F

Abstract

This report describes the results of a study to characterize two graphitic materials, graphite (ATJ-S) and carbon phenolic (RAD 6300), in uniaxial stress after undergoing heating to temperature near 6500 deg F. Heating rates up to 1000 deg F/second and strain rates up to 10/second were investigated. Test results as well as a complete description of the experimental technique developed in this program are discussed. Techniques include measuring strain using a laser extensometer, coating thin films on graphite using r.f. sputtering, and determining true test temperature.
