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 F. Heating rates up to 1000 Fsecond and strain rates up to 10second 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. Author
